Abstract

The invention provides an image correction method and device and medical equipment. The method comprises a scanning video during scanning of a patient is obtained; a skeleton image is extracted from each frame of the scanning video; the skeleton image is converted into a coordinate system of a video image to obtain a skeleton image in a corresponding video image; a skeleton displacement matrix ofeach moment in the patient scanning process is determined according to the skeleton image in the video image; and the displacement matrix is used to correct the position of the corresponding preprocessed video image to obtain a corrected video image. Thus, the problem that the image quality is decreased due to the fact that artifact caused by movement of a patient himself / herself cannot be detected in the prior art is solved.

Description

technical field [0001] The present application relates to image processing technology, in particular to an image correction method, device and medical equipment. Background technique [0002] When doing a whole-body examination on a patient, it is necessary to scan the whole body of the patient first with computerized tomography (CT, Computed Tomography) and then with a positron emission tomography (PET, Positron emissiontomography) scan; however, during the scanning process, due to Lying flat for long periods of time can cause some body parts to move, which will affect the quality of the generated images. [0003] In order to improve the quality of the generated image, in the prior art, it is judged whether the patient moves by detecting whether the contour position of the patient moves. That is to say, an ordinary camera is installed vertically above the patient, and the camera is used to take pictures of the patient to obtain the contour information of the patient. Then,...
