Abstract

The invention discloses a rapid CT scanning method and system based on a virtual stereotaxic image. The rapid CT scanning method comprises the steps: inputting patient images which are photographed atdifferent angles and comprise a to-be-scanned region, and carrying out the key point detection of the patient images; inputting a positioning image data template and marking key points; performing matching calculation according to the key points in the patient image and the positioning image data template to obtain a three-dimensional virtual positioning image; and determining a CT scanning areaof the patient according to the three-dimensional virtual positioning image, and outputting a final CT image. The virtual positioning image generated by the optical image is used for replacing a traditional positioning image, and the time required for scanning the positioning image is shortened, and the radiation dose received by a patient is reduced, and the anatomical structure of the patient can be clearly displayed, and a doctor can more accurately position a scanning area, and the workload of the doctor is reduced.

Description

technical field

[0001] The invention relates to the technical field of medical imaging, in particular to a fast CT scanning method and system based on a virtual stereotaxic image. Background technique

[0002] Currently, in the CT scanning process, in order to select a scan area more accurately, it is necessary to scan a scout image first, and then select a scan area in the scout image. Such as Figure 5 As shown, the general CT process includes: patient registration; acquisition of horizontal and / or vertical positioning images according to scanning requirements; CT scanning. Doctors usually judge the scanning area of ​​the patient's positioning image based on experience, and the positioning image obtained by this method is not accurate. The Chinese patent "A Method and System for Intelligent Scanning Stereoscopic Monitoring" with the publication number CN110338835A discloses a method and system in which an auxiliary camera is used to capture an image of a patient to be sca...
