Problems solved by technology

In addition, the actual image imaging range of CT scanning varies greatly depending on the scanning mode, collimation layer thickness, gantry rotation time, and pitch. If the image cannot be imaged or the image is incomplete outside the effective scanning range, it is necessary to adjust the position of the patient on the scanning table and re-scan the positioning image. For example, when scanning the patient's head, if the patient's head is too close to the starting end of the scanning table , the scan cannot completely cover the entire head. In this way, the position of the patient on the scanning bed may need to be adjusted multiple times during the scan, which reduces the efficiency of CT scanning, wastes medical resources, and the patient is exposed to radiation from multiple scans. And other issues

Abstract

The invention discloses a method, device, equipment and storage medium for identifying an effective scanning range of a CT scanning bed, wherein the method comprises: in different scanning modes, simulating running a scanning bed with different groups of scanning parameters, and each group of scanning A scanning bed image is formed under the parameters; a plurality of scanning bed images formed under multiple sets of simulation parameters are obtained; the imaging data of each scanning bed image is determined according to all scanning bed images, each scanning bed image corresponds to a group of imaging data, and each The image data includes the bed start point, bed end point and scan length; compare multiple sets of imaging data to determine a group of imaging data with the smallest scan length in each group of imaging data. CT scan bed for location marking. According to the method for identifying the effective scanning range of the CT scanning bed of the present invention, the effective scanning range of the scanning can be marked, which is beneficial to improve the scanning efficiency, make full use of medical resources, and at the same time, avoid the problem of multiple scanning radiation for patients.

Description

technical field [0001] The invention relates to the technical field of CT scanning, in particular to a method, device, equipment and storage medium for identifying an effective scanning range of a CT scanning bed. Background technique [0002] CT (Computed Tomography), that is, electronic computed tomography, which uses a precisely collimated X-ray beam and a highly sensitive detector to rotate continuously around a certain part of the human body to collect information and reconstruct multiple cross-sectional images of the part. , has the characteristics of fast scanning time, clear images without overlapping, etc., and can be used for the inspection of various diseases. [0003] During CT scanning, the patient lies on the scanning bed and does not move, and uses the motion of the scanning bed to cooperate with the continuous rotation of the tube detector to scan the patient on the scanning bed. During the scanning process, the scanning bed needs to accelerate from a static ...
