Embodiment Construction

[0022] Hereinafter, embodiments embodying the present invention will be described based on the drawings.

[0023] (Overall structure of X-ray imaging device)

[0024] refer to Figure 1 to Figure 9 The X-ray imaging apparatus 100 according to one embodiment of the present invention will be described.

[0025] Such as figure 1 As shown, the X-ray imaging device 100 performs X-ray imaging to identify a foreign object 200 remaining in the body of the subject 101 after surgery. The X-ray imaging apparatus 100 performs X-ray imaging for checking whether a foreign object 200 remains in the body of a subject 101 who has undergone a laparotomy in an operating room. The X-ray imaging apparatus 100 is, for example, an X-ray imaging apparatus for rounds in which the entire apparatus is movable. The foreign matter 200 includes, for example, surgical gauze, a suture needle, and forceps (hemostat, etc.).

[0026] Usually, when surgical operations such as laparotomy are performed, opera...

Abstract

The invention provides an X-ray imaging apparatus, an image processing method, and a method for generating a learned model. An X-ray imaging device is provided with an X-ray irradiation unit, an X-ray detection unit, an X-ray image generation unit, and a control unit. Furthermore, the control unit includes: an emphasized image generation unit that generates an emphasized image in which foreign matter included in the X-ray image is emphasized; a recognition image generation unit that generates a recognition image for recognizing the foreign matter by coloring a portion corresponding to the emphasized foreign matter on the basis of the emphasized image; and an image output unit that outputs the recognition image.

Description

technical field [0001] The present invention relates to an X-ray imaging device, an image processing method, and a method for generating a learned model, and in particular, to an X-ray imaging device for identifying foreign objects remaining in a subject's body after surgery, and an image processing method. The processing method and the generation method of the learned model. Background technique [0002] Conventionally, there is known a radiographic system (X-ray imaging device) that performs a radiographic examination (X-ray imaging) for confirming the presence or absence of hemostatic gauze (foreign matter) after a laparotomy. For example, one such radiographic system is disclosed in Japanese Patent Application Laid-Open No. 2019-180605. [0003] The radiographic system described in Japanese Patent Application Laid-Open No. 2019-180605 above processes radiographic images in accordance with a preset processing procedure according to inspection purposes. For example, when...
