Embodiment Construction

[0050] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0051] The non-beam limiter region detection method provided by this application can be applied to such as figure 1 shown in the application environment. The application environment involves the terminal 102 and may also involve the server 104 . The terminal 102 communicates with the server 104 through the network. After the terminal 102 receives the detection instruction from the user, the detection method of the non-beam limiter area can be completed independently through the terminal 102 in response to the detection instruction. The detection instruction can also be ...

Abstract

The invention relates to a non-beam-limiter area detection method and device, computer equipment and a storage medium. The method comprises the following steps: detecting a medical image by using a preset segmentation model to obtain a target region probability distribution diagram; generating a target area mask graph corresponding to the medical image based on the target area probability distribution graph; and obtaining a non-beam-limiter region according to the target region mask pattern. The method can improve the accuracy.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a detection method, device, computer equipment and storage medium of a non-beam limiter region. Background technique [0002] In X-ray equipment, the beam limiter is used to block the area where the subject does not need to receive X-rays, so as to reduce the dose of X-rays received by the subject. Therefore, an image usually imaged with an X-ray device includes a beam-limited region and a non-beam-limited region. Since the area blocked by the beam limiter is a non-diagnostic area, it needs to be excluded in the final imaging image. Incorrect exclusion of beam limiter regions can result in missing diagnostic regions, resulting in waste films. When the beam limiter area is not completely excluded, the remaining beam limiter area will also have a certain impact on the overall contrast of the image and the image processing effect. Therefore, it is necessary to ...
