TECHNICAL FIELD

The present disclosure generally relates to a medical imaging device, and more specifically, relates to systems and methods for controlling a medical imaging device via a mobile device.

BACKGROUND

Medical imaging systems are used for a variety of applications in the field of medicine. For example, medical imaging systems such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET) may be used for diagnosis purposes. Merely by way of example, in a CT system, a user (e.g., a doctor) may control to perform one or more operations (e.g., scanning of an object and/or image reconstruction) via a terminal device. In some embodiments, the terminal device may stay at a fixed location. Besides, the terminal device may communicate with other components of the CT system via a wired network.

In 910, a control instruction may be received from a mobile device (e.g., the mobile device 710) via a network (e.g., the network 120). Merely by way of example, the control instruction may relate to controlling the movement of a gantry (e.g., the gantry of the scanner 721), and/or controlling the movement of a scanning table (e.g., the scanning table 723). In some embodiments, the control instruction may be generated by the processor 714 of the mobile device 710 based on data related to an object, one or more scanning parameters, etc. For example, the processor 714 may generate a control instruction based on the scanning parameter(s), such as tilt angle of a gantry, rotation velocity of the gantry, tilt angle of a scanning table, etc. The control instruction may be generated before or during a scan process.

Specifically, the control module 727 may include a driver. The driver may generate mechanical energy to move the gantry based on the control instruction. In some embodiments, the control module 727 may perform at least one of: adjusting a tilt angle of the gantry relative to a horizontal plane, controlling a deflection angle of the gantry, controlling a rotation velocity of the gantry, and/or controlling a rotation direction of the gantry. The tilt angle of the gantry relative to the horizontal plane may relate to a tilt angle of a rotation axis of the gantry (i.e., the Z-axis direction in FIG. 1) relative to the horizontal plane, and in general, the tilt angle may be set as zero. The deflection angle of the gantry may relate to an initial angle of the gantry. The initial angle of the gantry may relate to a line connecting the radiation source and the detector, which are oppositely mounted on the gantry. If the line connecting the radiation source and the detector is vertical, the initial angle may be designated as zero. The rotation velocity of the gantry may relate to a velocity of the gantry rotating along the rotation axis. In some embodiments, the rotation velocity of the gantry may be determined based on a scan plan, such as the scanning time, the radiation dose, the scan region of the object, etc. The rotation direction of the gantry may include a counterclockwise rotation or a clockwise rotation.

In some embodiments, the control module 727 may control the movement of the gantry of the scanner 721 before the scan process. For example, before the scan process, the control module 727 may adjust the tilt angle of the gantry to be zero (e.g., the rotation axis of the gantry being parallel to the horizontal plane) in response to the control instruction. As another example, before the scan process, the control module 727 may adjust a deflection angle of the gantry (e.g., an initial angle of the gantry) to be zero in response to the control instruction. In some embodiments, the control module 727 may control the movement of the gantry during a scan process. For example, the control module 727 may adjust the rotation velocity or the rotation direction of the gantry during the scan process in response to the control instruction.

In 930, the movement of a scanning table (e.g., the scanning table 723) may be controlled in response to the control instruction. In some embodiments, the control instruction may be related to controlling the movement of the scanning table (e.g., the scanning table 723). The medical imaging device (e.g., the control module 727 of the medical imaging device 720) may control the movement of the scanning table (e.g., the scanning table 723) in response to the control instruction. The driver of the control module 727 may generate mechanical energy to move the scanning table 723 based on the control instruction. In some embodiments, the control module 727 may perform at least one of controlling a moving distance of the scanning table 723 with respect to the gantry of the scanner 721, controlling a moving direction of the scanning table 723 with respect to the gantry, controlling a moving velocity of the scanning table 723, controlling a moving acceleration of the scanning table 723, and/or controlling a tilt angle of the scanning table 723. The moving distance and/or moving direction of the scanning table 723 may relate to an actual positional relationship between the gantry of the scanner 721 and the scanning table 723, and the desired positional relationship thereof. In some embodiments, the positional relationship (e.g., the actual positional relationship, the desired positional relationship) may indicate a distance between the gantry of the scanner 721 and the scanning table 723 (e.g., a distance between a head of the scanning table 723 and a front end of the gantry). In some embodiments, the moving velocity of the scanning table 723 may include a uniform velocity, a non-uniform velocity, etc. The moving acceleration of the scanning table 723 may indicate a change in the moving velocity of the scanning table 723 divided by time. In some embodiments, the moving acceleration of the scanning table 723 may include a uniform acceleration, a non-uniform acceleration, a positive acceleration, a negative acceleration, etc. The tile angle of the scanning table 723 may relate to an angle of the bed board of the scanning table 723 relative to the horizontal plane.

In some embodiments, the control module 727 may control the movement of the scanning table 723 before the scan process. For example, before the scan process, the control module 727 may move the scanning table 723 towards or away from the gantry of the scanner 721 in response to the control instruction. As another example, before the scan process, the control module 727 may adjust the tile angle of the scanning table to be zero. In some embodiments, the control module 727 may control the movement of the scanning table 723 during the scan process. For example, the control module 727 may control the moving distance and/or moving direction of the scanning table 723 in the inspection chamber of the gantry during the scan process. If an object (e.g., a patient) on the scanning table 723 has finished a head scan and is to start a chest scan, the control module 227 may control the moving distance and/or moving direction of the scanning table 312 in the inspection chamber of the gantry 410. As another example, the control module 727 may control the moving velocity and/or moving acceleration of the scanning table 723 during the scan process. In some embodiments, the moving velocity and/or the moving acceleration may be default settings of the medical imaging device or adjusted before or during the scan process by a user (e.g., a doctor).

It should be noted that the above description of the process 900 is provided for the purposes of illustration, and is not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. In some embodiments, the control module 727 may perform steps 920 and 930 in any order. For example, the control module 727 may perform steps 920 and 930 simultaneously. As another example, the control module 727 may perform step 920 before or after step 930.

FIG. 10 is a flowchart illustrating an exemplary process 1000 for scanning an object according to some embodiments of the present disclosure. The process 1000 may be executed by the medical imaging system 100. For example, the process 1000 may be implemented as a set of instructions (e.g., an application) stored in a processor of the medical imaging system 100 (e.g., a processor in the processing device 140 illustrated in FIG. 1). The processor in the processing device 140 may execute the set of instructions and may accordingly be directed to perform the process 1000. The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 1000 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process as illustrated in FIG. 10 and described herein is not intended to be limiting.

In 1010, a scan instruction may be received from a mobile device (e.g., the mobile device 710) via a network (e.g., the network 120). Merely by way of example, the scan instruction may relate to adjusting one or more scanning parameters of a scanner (e.g., the scanner 721), scanning an object and generating scanning data related to the object, etc. In some embodiments, the scan instruction may be generated by the processor 714 of the mobile device 710 based on data related to an object, one or more scanning parameters, etc. For example, the processor 714 may generate a scan instruction based on the scanning parameter(s) (e.g., scanning time, irradiation dose). In some embodiments, the scan instruction may be in the form of a digital signal and/or analog signal. A medical imaging device (e.g., the second communication port 725 of the medical imaging device 720) may receive the scan instruction via the network (e.g., the network 120).

In 1020, one or more scanning parameters of a scanner (e.g., the scanner 721) may be adjusted in response to the scan instruction. In some embodiments, the scan instruction may relate to adjusting the scanning parameter(s) of the scanner (e.g., the scanner 721). In some embodiments, the scanning parameter(s) may include scanning time, irradiation dose, slice thickness of scanning, tube voltage, tube current, or the like, or any combination thereof. The scanner (e.g., a processor of the scanner 721) may adjust the scanning parameter(s) in response to the scan instruction.

In 1030, an object may be scanned in response to the scan instruction. In some embodiments, the scan instruction may relate to scanning an object and generating scanning data related to the object. In some embodiments, the scanner (e.g., the scanner 721) may perform a scan process to scan the object in response to the scan instruction. The scanner (e.g., the scanner 721) may generate scanning data related to the object during the scan process. In some embodiments, the scanning data related to the object may include a plurality of data for reconstruction.

In 1040, the scanning data related to the object may be transmitted via the network (e.g., the network 120) to be displayed on the mobile device (e.g., the mobile device 710). In some embodiments, the medical imaging device (e.g., the second communication port 725 of the medical imaging device 720) may transmit the scanning data to the mobile device (e.g., the mobile device 710) via the network (e.g., the network 120). The scanning data may be displayed on a display (e.g., the display 718). A user (e.g., a doctor) may look through the scanning data to make a further scan plan or a treatment plan. In some embodiments, the scanning data may be stored in a storage of the medical imaging device for further processing, for example, image reconstruction.

It should be noted that the above description of the process 1000 is provided for the purposes of illustration, and is not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, step 1020 may be omitted, and one or more default scanning parameters may be applied during the scan process.

FIG. 11 is a flowchart illustrating an exemplary process 1100 for reconstructing one or more images according to some embodiments of the present disclosure. The process 1100 may be executed by the medical imaging system 100. For example, the process 1100 may be implemented as a set of instructions (e.g., an application) stored in a processor of the medical imaging system 100 (e.g., a processor in the processing device 140). The processor in the processing device 140 may execute the set of instructions and may accordingly be directed to perform the process 1100. The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 1100 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process as illustrated in FIG. 11 and described herein is not intended to be limiting.

In 1110, a data processing instruction may be received from a mobile device (e.g., the mobile device 710) via a network (e.g., the network 120). The data processing instruction may relate to image reconstruction based on scanning data. In some embodiments, the data processing instruction may be generated by the processor 714 of the mobile device 710. For example, the processor 714 may generate the data processing instruction based on one or more reconstruction parameters (e.g., a reconstruction function, iteration times of reconstruction). In some embodiments, the data processing instruction may be in the form of a digital signal and/or analog signal. A medical imaging device (e.g., the second communication port 725 of the medical imaging device 720) may receive the data processing instruction via the network (e.g., the network 120).

In 1120, one or more images of an object may be reconstructed based on scanning data in response to the data processing instruction. In some embodiments, the medical imaging device (e.g., the image reconstruction module 729 of the medical imaging device 720) may reconstruct the image(s) based on the scanning data in response to the data processing instruction. The scanning data may be generated during a scan process (e.g., as described elsewhere in the present disclosure in connection with FIG. 10). In some embodiments, the image(s) may include two-dimensional (2D) image(s), three-dimensional (3D) image(s), four-dimensional (4D) image(s), or the like, or any combination thereof.

In 1130, the one or more images of the object may be transmitted via the network (e.g., the network 120) to be displayed on the mobile device (e.g., the mobile device 710). In some embodiments, the medical imaging device (e.g., the second communication port 725 of the medical imaging device 720) may transmit the image(s) to the mobile device (e.g., the mobile device 710) via the network (e.g., the network 120). The image(s) may be displayed on a display (e.g., the display 718). A user (e.g., a doctor) may look through the image(s) to make a further scan plan or a treatment plan. In some embodiments, the image(s) may be stored in a storage of the medical imaging device.

It should be noted that the above description of the process 1100 is provided for the purposes of illustration, and is not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. In some embodiments, the data processing instruction may relate to other data processing, such as imaging segmentation, image amplification, image reduction, etc. The medical imaging device may further process the reconstructed image(s) based on the data processing instruction.
