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 an identification method, device and equipment for an effective scanning range of a CT scanning bed and a storage medium. The identification method comprises the steps that thesimulated operation of the scanning bed is carried out through a plurality of different groups of scanning parameters in different scanning modes, and a scanning bed image is formed under each groupof scanning parameters; a plurality of scanning bed images formed under a plurality of groups of simulation parameters are obtained; imaging data of each scanning bed image is correspondingly determined according to all the scanning bed images, each scanning bed image corresponds to a group of imaging data, and each group of imaging data comprises a bed starting point, a bed end point and a scanning length; and the multiple groups of imaging data are compared, a group of imaging data with the smallest scanning length in each group of imaging data is determined, and the position of the CT scanning bed is marked according to the bed starting point and the bed end point in the group of imaging data. According to the identification method for the effective scanning range CT of the CT scanningbed, the scanned effective scanning range can be marked, the scanning efficiency can be improved, and medical resources are fully utilized; and meanwhile, the problem of repeated scanning radiation ofa patient is solved.

Description

technical field [0001] The present invention relates to the technical field of CT scanning, in particular to a method, device, equipment and storage medium for marking the effective scanning range of a CT scanning bed. Background technique [0002] CT (Computed Tomography), that is, computerized tomography, uses a precisely collimated X-ray beam and a highly sensitive detector to continuously rotate around a certain part of the human body and collect information to 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 examination of various diseases. [0003] During CT scanning, the patient lies on the scanning bed without moving, and the patient on the scanning bed is scanned by using the movement of the scanning bed and the continuous rotation of the tube detector. During the scanning process, the scanning bed needs to be accelerated from a static state to a ...
