It is to be appreciated by those skilled in the art that the present disclosure may also be practiced without certain details. In some embodiments, methods, means, elements, and circuits well known to those skilled in the art are not been described in detail, to highlight the subject of the disclosure.

FIG. 1 illustrates a flowchart of a method for displaying a target object according to embodiments of the present disclosure. The method is applied to a device for displaying a target object. For example, in the case where the device is deployed for execution in a terminal device, a server or other processing devices, at least one to-be-analyzed object (such as a nidus in a lesion region) may be displayed and positioned, and a range of area where the to-be-analyzed object is distributed may be determined. The terminal device may be user equipment (UE), a mobile device, a cellular telephone, a cordless telephone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or the like. In some possible implementations, the processing method may be implemented by a processor invoking computer-readable instructions stored in a memory. As illustrated in FIG. 1, the procedure includes the following actions S101 to S103.

At S101, at least one to-be-analyzed object is displayed in response to a first operation for the target object.

In some possible implementations, the target object is a blood vessel as an example. The first operation may be an operation of selecting the blood vessel, and the at least one to-be-analyzed object may be a vascular plaque in a lesion region, or a nidus in another non-vascular region. When the blood vessel is selected, a vascular plaque in at least one lesion region in the blood vessel, and/or a nidus in at least one non-vascular region may be displayed.

At S102, an anchor point for determining one of the at least one to-be-analyzed object is obtained, in response to a second operation for the target object.

In some possible implementations, the at least one to-be-analyzed object may be a vascular plaque in a lesion region, or a nidus in another non-vascular region. With the target object being a blood vessel as an example, the at least one to-be-analyzed object may be multiple vascular plaques, and the second operation may be an operation of positioning any one of the multiple vascular plaques. The at least one to-be-analyzed object may also be multiple nidi in a non-vascular region, and the second operation may be an operation of positioning any of the nidi in the non-vascular region. By parsing the second operation, an anchor point corresponding to the second operation may be obtained, and the anchor point may be used to position any of the at least one to-be-analyzed object.

At S103, according to acquired object distribution images and the anchor point, a range of area where the to-be-analyzed object corresponding to the anchor point is located in the target object is determined.

In some possible implementations, the object distribution images may include: an image of a distribution range of the at least one to-be-analyzed object in the target object, for example, multiple cross-sectional views of the blood vessel corresponding to positions on the blood vessel. Here, different cross-sectional views of the blood vessel are obtained at different regional positions on the blood vessel.

By means of the embodiments of the present disclosure, object distribution images can be obtained. According to the distribution range of at least one to-be-analyzed object in the target object in the object distribution images, an intuitive interface design can assist the user to obtain an accurate judgment result of the object distribution range.

In an example, in some possible implementations, before displaying the at least one to-be-analyzed object in response to the first operation for the target object, the method may further include the following actions: obtaining a feature vector corresponding to the at least one to-be-analyzed object; each of the at least one to-be-analyzed object is recognized according to the feature vector and a recognition network; and each of the at least one to-be-analyzed object is identified to obtain a display identifier. The at least one to-be-analyzed object may include: multiple objects displayed according to display identifiers.

By means of the embodiments of the present disclosure, the at least one to-be-analyzed object can be recognized according to the feature vectors and the recognition network, and each of the at least one to-be-analyzed object can be identified to obtain a display identifier. By displaying the at least one to-be-analyzed object through the display identifier, the user can be assisted to quickly determine the to-be-analyzed object according to the intuitive interface design, and perform needed analysis judgment on the to-be-analyzed object.

In some possible implementations, after determining the range of area where the current to-be-analyzed object corresponding to the anchor point is located in the target object, the method may further include: in response to a third operation (an operation of selecting a vascular plaque) for the current to-be-analyzed object corresponding to the anchor point, a feature object (such as a vulnerable sign under the vascular plaque) that corresponds to the current to-be-analyzed object corresponding to the anchor point is displayed. The feature object has a nature of lesion different from that of the current to-be-analyzed object corresponding to the anchor point.

In the embodiments of the present disclosure, at least one to-be-analyzed object (such as a vascular plaque in a lesion region) is displayed in response to a first operation for the target object; an anchor point for determining one of the at least one to-be-analyzed object is obtained in response to a second operation for the target object; according to acquired object distribution images (such as cross sections of the blood vessel corresponding to the anchor point of the vascular plaque) and the anchor point, the range of area where the current to-be-analyzed object corresponding to the anchor point is located in the target object is determined. By means of the embodiments of the present disclosure, positional relationships of such as the target object and the anchor point can be clearly obtained in the visual interface design, and the display effect of the interface design is intuitive, so that the user can obtain accurate judgment results based on the intuitive interface design.

Embodiments of the present disclosure are described below by way of example. Firstly, the action S101 that at least one to-be-analyzed object is displayed in response to a first operation for the target object is explained. In this embodiment, the target object is a blood vessel and the to-be-analyzed object is a vascular plaque as an example. When a first operation for the blood vessel (such as an operation of selecting the blood vessel) is received, at least one vascular plaque in a lesion region in the blood vessel is displayed. Before action S101, a feature vector corresponding to the at least one vascular plaque in the blood vessel may be obtained, and each of the at least one vascular plaque is recognized according to the feature vector and a recognition network. In a possible implementation, a display identifier may be added to each of the at least one vascular plaque, and after receiving the first operation for the blood vessel, each vascular plaque is displayed according to the display identifier of the vascular plaque.

Following the above explanation of action S101, it is continued to explain action S102 that an anchor point for determining one of the at least one to-be-analyzed object is obtained in response to a second operation for the target object. In this embodiment, after the blood vessel is displayed and the at least one vascular plaque is displayed, an anchor point of a vascular plaque corresponding to a second operation can be obtained after receiving the second operation for the blood vessel (such as an operation of positioning any vascular plaque displayed in the blood vessel).

Following the above explanation of action S102, it is continued to explain action S103 that a range of area where the to-be-analyzed object corresponding to the anchor point is located in the target object is determined according to acquired object distribution images and the anchor point. In this embodiment, object distribution images corresponding to the blood vessel are acquired. The object distribution images may include cross-sectional views of the blood vessel at different positions of the blood vessel. According to the cross-sectional views of the blood vessel at the different positions of the blood vessel and the anchor point, a range of area where the vascular plaque selected in action S102 is located in the blood vessel can be obtained.

Following the above explanation of action S103, some other possible embodiments are described. After determining the range of area where the vascular plaque selected in action S102 is located in the blood vessel, a third operation for the vascular plaque (for example, an operation of selecting the vascular plaque) may be acquired, and a feature object corresponding to the vascular plaque may be displayed. For example, a vulnerable sign corresponding to the vascular plaque may be displayed. In some possible implementations, the vulnerable sign may have a nature of lesion different from that of the current to-be-analyzed object.

By means of the embodiments of the present disclosure, the displayed feature object can be obtained in response to the third operation, and an object having a nature of lesion different from that of the to-be-analyzed object can be obtained through the feature object.

FIG. 2 illustrates a schematic diagram of object identification legends for a target object being a blood vessel according to embodiments of the present disclosure, including: a display identifier 21 of a plaque on the blood vessel, a display identifier of a vulnerable sign 23 corresponding to the plaque, a display identifier 22 of a blood vessel pointer for positioning, and the like. The embodiments of the present disclosure are not limited to the object identification legends illustrated in FIG. 2. Any identification forms that can distinguish different objects from one another, and are capable of ensuring that multiple object legends are highly distinguished from each other shall fall within the scope of the embodiments of the present disclosure.

As illustrated in FIG. 2, at least one to-be-analyzed object can be recognized in the target object according to the artificial intelligence technology by such as the feature vectors and the recognition network described above. Correspondingly, the at least one to-be-analyzed object is identified and displayed to the user by the object identification legends in FIG. 2 respectively. In some possible implementations, the object identification legends may include, but are not limited to, plaques, blood vessel pointers, and vulnerable signs, in the case where the target object is a blood vessel. Different object legends are highly distinguished from each other. Thus, lesions of different natures are displayed with highly distinguishable display identifiers, which is convenient for a user to review; furthermore, positional relationships of such as the target object and the anchor point corresponding to the display identifiers can be clearly obtained through different display identifiers in the visual interface design, so that the user can obtain an accurate judgment results of the lesion according to the visual interface design.

In some possible implementations, with the target object being a blood vessel as an example, the to-be-analyzed object may be a vascular plaque in a lesion region displayed in response to a first operation.

FIG. 3 illustrates a schematic diagram of positional relationships of a target object which is a blood vessel, and an anchor point on according to embodiments of the present disclosure.

As illustrated FIG. 3, the object distribution images 11 may be multiple cross-sectional views of the blood vessel corresponding to positions on the blood vessel. An anchor point for determining any of the at least one to-be-analyzed object, i.e., the vascular plaque is obtained, such as an anchor point limited by the first position identifier 121 and the second position identifier 122 in response to a second operation (which may be an operation of positioning any one of multiple vascular plaques in the blood vessel) for the target object (i.e., the blood vessel).

According to the acquired object distribution images, multiple cross-sectional views of the blood vessel corresponding to positions on the blood vessel are acquired. According to the position of the anchor point limited by the first position identifier 121 and the second position identifier 122 in the multiple cross-sectional views of the blood vessel, a range of section in which the to-be-analyzed object corresponding to the anchor point is located in the target object is determined. Thus, the user can learn that the plaque corresponding to the present anchor point is positionally located in a certain range of section in the entire blood vessel (for example, the screen shot 111 illustrated distinguishably from those at other positions among the object distribution images 11).

FIG. 3 also includes positional relationships of to-be-analyzed objects and anchor points, and an operation menu 13 triggered by a right button of a mouse in the case where the target object is a blood vessel.

The to-be-analyzed objects not only include a vascular plaque 14, but may also include vulnerable signs 15 located under the vascular plaque 14 of the blood vessel 16. It may be triggered to display the vulnerable signs after a vascular plaque is selected.

In some possible implementations, a clear and intuitive interface display effect can be obtained by the different display modes and the displayed position relationship of the to-be-analyzed objects, thereby facilitating a user in viewing and determine the positional relationship of to-be-analyzed objects. For example, the blood vessel may be selected according to the first operation of the user, to display all plaques under the blood vessel on the interface. Alternatively, all vascular plaques under the blood vessel may be directly displayed according to actual application requirements, without being limited to being triggered by an operation. Any one of the vascular plaques is selected for view, according to the second operation of the user. The present position is obtained according to the anchor point and the multiple cross-sectional views of blood vessel. That is, the position of the vascular plaque, corresponding to the anchor point pointed to by the mouse pointer, in the area of the entire blood vessel is determined according to the position of the anchor point in the multiple cross-sectional views of the blood vessel. Further, the vascular plaque may also be selected to display the location and range of vulnerable signs under the vascular plaque.

In some possible implementations, corresponding operations may be performed by directly clicking on the operation menu 13. There is no need to perform an additional switch action to enter a next operation, thereby simplifying the user operations and increasing the speed in interaction and feedback.

In some possible implementations, the display of the operation menu 13 may be triggered by right-click. The operation menu includes, but is not limited to, a reset option, a pan option, a zoom option, an inverted option, and a text option. By further selecting a target option in the operation menu 13, the operation corresponding to the target option can be selected. For example, after the user selects the pan option in the operation menu 13, the operation corresponding to the panning option is switched to. Namely, the pan operation is switched to.

In summary, with the disclosed embodiments, with different interactive display corresponding to different user operations, multiple lesions (such as vascular plaques, and vulnerable signs) of different natures can be distinguished and displayed. The position of the presently positioned vascular plaque in the range of the entire blood vessel can be learned based on the anchor point corresponding the present plaque and the above multiple cross-sectional views. Therefore, better positioning can be achieved based on the interface display identifiers and the interactive display.

In some possible implementations, the action that the range of area where the current to-be-analyzed object corresponding to the anchor point is located in the target object is determined according to the acquired object distribution images and the anchor point may include: a reference image corresponding to the anchor point is obtained from the object distribution images; and the range of area where the current to-be-analyzed object corresponding to the anchor point is located in the target object is determined according to a serial number or ranking position of the reference image among the object distribution images. For example, if the serial number is 2, the ranking position is the second in the multiple cross sections, indicating that the range of area is at an upper position compared to the initial anchor point of the target object (e.g., the initial anchor point is in the middle of the target object).

By means of the embodiments of the present disclosure, a reference image corresponding to the anchor point can be obtained from the object distribution images, so that the range of area where the to-be-analyzed object corresponding to the anchor point is located in the target object can be determined according to a serial number or ranking position of the reference image among the object distribution images.

In some possible implementations, after the reference image corresponding to the anchor point is obtained from the object distribution images, the method may further include: the reference image corresponding to the anchor point is displayed in a display mode different from a mode of displaying a non-reference image among the object distribution images to distinguish the reference image from the non-reference image, and an obtained display result is fed back to a user in real time. For example, among nine cross-sectional views corresponding to the positions on the blood vessels, the cross-sectional view corresponding to the present anchor point may be highlighted differently from the other cross-sectional views. Therefore, according to the anchor point and the highlight, the user can learn which range of section the plaque corresponding to the present anchor point is located in the entire blood vessel, thereby achieving better positioning and facilitating real-time viewing by the user.

By means of the embodiments of the present disclosure, the reference image corresponding to the anchor point and a non-reference image among the object distribution images may be distinguished from each other by displaying them in different display modes respectively. For example, the reference image may be highlighted to distinguish from a non-reference image, so as to assist the user to quickly obtain the reference image according to the intuitive interface design, so as to perform the needed analysis and judgment on the to-be-analyzed object.

In some possible implementations, the method may further include: in response to a position change of the anchor point, a range of area where a position-changed to-be-analyzed object is located in the target object is updated to obtain an updated result, that is, a new range of area different from that displayed in a previous area, by switching the current to-be-analyzed object to the position-changed to-be-analyzed object and synchronizing the position change of the anchor point to the object distribution images. For example, the vascular plaque may be switched along with an anchor point and synchronized to a corresponding cross-section view among the multiple cross-sectional views, so as to feed a new range of area of the vascular plaque corresponding to the position updated and changed anchor point in the entire blood vessel back to the user in real time, for easy view by the user.

By means of the embodiments of the present disclosure, in response to the position change of the anchor point, the range of area where the to-be-analyzed object corresponding to the position-changed anchor point is located in the target object can be synchronously updated in real time, to assist the user to switch to, in real time, the updated result obtained after the synchronous update, so as to make the required analysis and judgment on the to-be-analyzed object.

Hereinafter, an exemplary application of the embodiments of the disclosure in an actual application scenario will be described.

In medical images of hearts or some multi-level presentation, there may be such as blood vessels, plaques and vulnerable signs. Images of stenosis and plaque positions, and positional relationships related with the degree of stenosis need to be viewed when viewing blood vessels. Image of cross sections corresponding to the blood vessel also need to be viewed. Artificial intelligence is generally not used in existing technologies, and it is unable to automatically recognize lesion regions and lesion locations on all blood vessels, no specific nature or identifier is indicated, and no cross-sectional view corresponding to a position on the blood vessel is reflected, thus being unable to clearly reflect positional relationships of the lesions with the range of the blood vessels.

By means of embodiments of the present disclosure, a range of a plaque on a blood vessel and a range of a vulnerable sign on the blood vessel can be intuitively presented, and a distinguishable and intuitive mode of interaction for example plaque switching can be supported. It is also possible to indicate, on the blood vessel, the range of the cross-sectional views of a region corresponding to a pointer, so as to facilitate judgment based on the image.

As illustrated in FIG. 3, a curved planar reconstruction (CPR) image needs to be referred to when viewing a blood vessel. The number of plaques, the range and position of a plaque in the blood vessel, as well as the position and range of a vulnerable sign can be seen in the image, so that the physician can make judgment and positioning based on the entire artificial intelligence (AI) result clearly and visually.

When moving the blood vessel pointer to view the image of a corresponding cross section, i.e., in the zone 11 in FIG. 3, the range relationship of the plaque in the nine cross sections on the blood vessel can be seen in real time, facilitating positioning for the physician.

When diagnosing a cardiovascular disease, the physician needs to confirm and analyze conclusions given in the image and corresponding lesion regions. At this time, the physician needs to review and confirm blood vessels one by one. Reference should be made to the CPR image when viewing the blood vessels. The number of plaques, and the range and location of a plaque in the blood vessel, as well as the location and range of a vulnerable sign in the blood vessel can be seen in the CPR image, and the plaques and vulnerable signs can be switched directly on the image and synchronized in the list. This is convenient for the physician to make judgment and positioning based on the entire AI result clearly and intuitively.

When the blood vessel pointer is moved to view corresponding cross-sectional images, nine corresponding cross-sectional views may be presented in real time in FIG. 3. Moreover, while moving the blood vessel pointer, the range of area of a plaque in the cross sections of the blood vessel is displayed synchronously, so that the range relationship is clearly reflected and the positioning is better realized for the physician.

Embodiments of the present disclosure may be applied to an image reading system in an imaging department; scanning stations such as computed tomography (CT), magnetic resonance (MR), and positron emission tomography (PET); and all logical operations having a correspondence relationship, such as AI-assisted diagnosis, an AI labeling system, telemedicine diagnosis, and cloud platform-assisted intelligent diagnosis.
