Abstract

The invention provides a CT scanning auxiliary method and device and a computer readable storage medium, and relates to the technical field of CT scanning. The whole CT scanning is divided into threestages, and a corresponding technical scheme is provided for factors which may cause poor CT image quality in each stage. Before scanning, the problem that the quality of a final CT scanning reconstructed image is poor due to incorrect initial positioning of a patient is avoided by detecting the positioning of the patient, in the scanning process, by detecting the position of the patient, the problem that the quality of a final CT scanning reconstructed image is poor due to position change of the patient is avoided, if movement of the patient is detected, scanning is prompted to be interrupted, so that the patient is prevented from receiving unnecessary doses, and after scanning is finished, quality evaluation is carried out on the final CT scanning reconstructed image, and the CT scanningreconstructed image with poor quality is eliminated, so that a doctor is prevented from being influenced and judged by the low-quality CT scanning reconstructed image in the subsequent diagnosis process.

Description

technical field [0001] The present invention relates to the technical field of CT scanning, in particular to a CT scanning auxiliary method, device and computer-readable storage medium. Background technique [0002] CT (computed tomography imaging system) uses X-rays to scan objects to obtain projection data, and process these projection data through tomographic reconstruction algorithms to obtain the object's tomography and three-dimensional density information to achieve the purpose of non-destructive testing ( figure 1 ). It has important applications in medical diagnosis, industrial non-destructive testing and other fields. In the field of medical diagnosis, CT has become the three key medical imaging systems together with magnetic resonance (MRI), positron emission tomography and CT combination system (PET / CT) since its advent in 1970. Compared with other imaging methods, CT reconstruction can quickly obtain high-resolution images, the contrast accuracy of the reconst...
