The present invention relates to an X-ray imaging system and a method for recognizing a foreign object.
Conventionally, a gauze counting device that counts the number of used gauze sponges that are used during a surgical operation is known to make sure whether the used gauze sponge is left inside a patient (subject) body or not. Such a gauze counting device is disclosed in JP 2018-48905 A.
The gauze counting device disclosed in JP 2018-48905 A comprises an X-ray generation element that irradiates X-rays to a gauze sponge housing that houses a plurality of gauze sponges in which contrast strings are woven and an X-ray imaging element that images an X-ray fluoroscopic image relative to the gauze sponge housing. The gauze counting device disclosed in JP 2018-48905 A calculates (counts) the number of gauze sponges from the image constructed based on the imaged X-ray fluoroscopic image.
Whereas, when a counting mistake takes place on counting, the results of respective counting numbers before and after the surgical operation may coincide with each other despite leaving a surgical instrument such as used gauze sponge inside the patient (subject) body. Accordingly, not disclosed in JP 2018-48905 A are measures to make sure whether any surgical instrument such as used gauze sponge (foreign object), which is left inside the patient (subject) body, or not, by taking an X-ray image regardless coincidence of counting results before and after the surgical operation would be undertaken.
Nevertheless, an oversight may take place due to the reason of which a surgical instrument (foreign object) overlaps such as the used gauze sponge and a structure of the human body such as a bone even if it was confirmed that no foreign object of the surgical instrument such as the used gauze sponge is not left inside the patient (subject) body thereof by taking the X-ray image. Therefore, a prevention of an occurrence of the oversight of the foreign object, which is left inside the subject body after the surgical operation, is desirable.
The present invention relates to addressing at least one of the aforementioned problems, and an object of the present invention is to provide an X-ray imaging system that can prevent an occurrence of an oversight relative to the foreign object left inside the subject body after the surgical operation and a method for recognizing such a foreign object left inside the body of the subject.
An X-ray imaging system according to a first aspect of the present invention comprises an X-ray imaging apparatus further comprising an X-ray irradiation unit that irradiates an X-ray to a subject, a detection unit that detects the X-ray that is irradiated from the X-ray irradiation unit and transmits through the subject, an X-ray image generation unit that generates an X-ray image based on the detection signal that is detected by the X-ray detection unit, a foreign object image generation unit that generates a foreign object image to recognize a foreign object left inside the subject body after a surgical operation based on the X-ray image, and a first display unit that display at least one image selected from a group consisting of the X-ray image and the foreign object image, and a second display unit that displays the foreign object image, wherein the second display unit is installed separately from the X-ray imaging apparatus and connected to the X-ray imaging apparatus via a network, and a visual recognition level of the second display unit is better than a visual recognition level of the first display unit.
A method for recognizing a foreign object according to a second aspect of the present invention comprises a step of irradiating an X-ray to a subject, a step of detecting the X-ray that transmits through the subject; a step of generating an X-ray image based on detection signals detected thereby, a step of generating a foreign object image to recognize a foreign object left inside the subject body after a surgical operation based on the X-ray image, and a step of displaying the foreign object image on the second display unit, wherein the second display unit is installed separately from the X-ray imaging apparatus and connected to the X-ray imaging apparatus via a network, and a visual recognition level of the second display unit is better than a visual recognition level of the first display unit.
According to one alternative aspect of the present invention, with regard to the X-ray imaging system according to the first aspect and the method for recognizing the foreign object according to the second aspect, the foreign object image to recognize the foreign object left inside the subject body after the surgical operation is generated. And the second display unit that is installed separately from the X-ray imaging apparatus and provides the visual recognition level that is better than the visual recognition level of the first display unit, which the X-ray imaging apparatus is so equipped with, displays the foreign object image. Therefore, a user can visually recognize the foreign object image applied to recognize the foreign object left inside the subject body after the surgical operation on the second display unit that has better visual recognition level than the first display unit which the X-ray imaging apparatus equips with. As a result, comparing with the case when the user recognizes the foreign object on the first display unit, which the X-ray imaging apparatus is so equipped, the user can easily recognize the foreign object in the foreign object image, so that the present invention can provide the X-ray imaging system that can prevent an occurrence of an oversight as to the foreign object left inside the subject body after the surgical operation and the method for recognizing such a foreign object left inside the subject body.

The foreign object generation element 41 (control element 4) generates the foreign object image 52 to recognize (identify) the foreign object 102 while coloring the portion corresponding to the region including the detected foreign object 102.
The foreign object generation element 41 (control element 4) acquires an estimated region in which the foreign object 102 is included in the X-ray image 51 and also acquires a decided value by which the likelihood (reliability), which indicates the certainty level as to the foreign object 102 in the estimated region, is decided based on the X-ray image 51 and the learned model. And the foreign object generation element 41 (control element 4) generates the foreign object image 52 as a colored heat map image (color map image) in which respective colors change corresponding to the decided value. And according to Embodiment 1 and referring to
Further, the foreign object generation element 41 (control element 4) recognizes (identifies) the linear structure of the foreign object 102 and may generates the foreign object image 52 with coloring based on the recognized linear structure. For example, the foreign object generation element 41 (control element 4) may generates the foreign object image 52 as the heat map image (color map image) colored while varying corresponding to the density of the linear structure of the recognized foreign object 102.
In such a case, the foreign object generation element 41 (control element 4) detects the foreign object 102 in the X-ray image 51 and generates the image from which the foreign object 102 detected in the X-ray image 51 is removed based on the X-ray image 51 and the learned model generated by the machine learning. And the foreign object generation element 41 (control element 4) generates the foreign object image 52 based on the X-ray image 51 and the image from which the detected foreign object 102 is removed, For example, the foreign object generation element 41 (control element 4) acquires the difference between the image from which the detected foreign object 102 is removed and the X-ray image 51, recognizes the linear structure of the foreign object 102 based on the acquired difference, and generates the foreign object image 52 while coloring based on the linear structure of the recognized foreign object 102.
