CT scanning panorama real-time monitoring method and system

Abstract

The present invention discloses a CT scanning panorama real-time monitoring method and system. The method comprises the steps of: using different cameras to shoot multiple images including the entire hospital bed and patient images from different angles, and taking two images taken by different cameras at different angles of view. image; perform projection transformation on the two images respectively, calculate the overlapping length of the hospital bed in the two images, and stitch the images according to the overlapping length to obtain a panorama; locate the key points of the human body, including the key points of the face; motion detection and facial expression detection. The present invention collects images through multiple cameras, performs projection splicing processing on the images, generates a real-time panorama during the CT scanning process, and monitors the current state of the patient in real time without dead ends according to the panorama, so that the detection process will not be blocked by the frame. During the scanning process, the patient's status can be clearly seen, which is convenient for doctors to take corresponding measures according to the patient's status.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a CT scan panorama real-time monitoring method and system. Background technique [0002] In the current CT scanning process, there is a lack of measures to monitor the patient during the scanning process, so it is impossible to record and detect the state of the patient during the scanning process, for example: it is impossible to determine whether the patient is moving during the scanning process; it is impossible to judge when the patient is injected with a contrast agent The patient's current physical condition, etc. In the Chinese patent "An Intelligent Scanning Stereoscopic Monitoring Method and System" with the publication number CN110338835A, a scheme for assisting CT scanning with a camera is proposed. The whole recognition process is based on the first image collected to automatically recognize and obtain body position information. And objectively and quickly ju...

[0002] In the current CT scanning process, there is a lack of measures to monitor the patient during the scanning process, so it is impossible to record and detect the state of the patient during the scanning process, for example: it is impossible to determine whether the patient is moving during the scanning process; it is impossible to judge when the patient is injected with a contrast agent Patient's current physical condition, etc.

In the Chinese patent "An Intelligent Scanning Stereoscopic Monitoring Method and System" with the publication number CN110338835A, a scheme for assisting CT scanning with a camera is proposed. The whole recognition process is based on the first image collected to automatically recognize and obtain body position information. And objectively and quickly judge the scanning area, reduce the influence of the subjective factors of the scanning operator, and assist the scanning technician to manually locate and judge the scanning area. However, when the patent processes the image collected by the camera, it cannot completely eliminate the field of view when the camera collects the image. There is still a situation where the view is blocked by the rack, and the continuously collected images cannot reflect in real time whether the current installation position of the camera is appropriate
