Problems solved by technology

When multiple intermittent scans are performed, when the forward direction of the scanning table changes during the scanning process, the scanning process needs to be interrupted by power failure, etc., and the clinical scanning workflow is complicated; while a single continuous scan is performed, during the image reconstruction process It is necessary to perform complex preprocessing on the scanned raw data to determine the moment when the forward direction of the scanning table changes and the timing of imaging, and the image reconstruction method is complex

Abstract

The embodiment of the invention discloses a perfusion scanning image reconstruction method and device, an image scanning apparatus and a storage medium. The method comprises the following steps: obtaining perfusion scanning data and corresponding perfusion scanning parameters; determining a scanning inflection point of at least one time point indicative of a movement direction change of the scanning table according to perfusion scanning parameters; obtaining at least two-stage perfusion scan data sets by dividing perfusion scanning data according to at least one scan inflection point; reconstructing the perfusion scanning data of each stage, and obtaining the reconstructed images. By introducing the scanning inflection point to reconstruct the perfusion scanning data obtained by a single continuous scanning step by step, the technical scheme simplifies the workflow of clinical scanning and the data processing calculation amount in the image reconstruction, thereby improving the imagingefficiency of the image scanning equipment.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical equipment, and in particular to a perfusion scanning image reconstruction method and device, an image scanning device, and a storage medium. Background technique [0002] Dynamic perfusion imaging refers to repeated scanning of the site of interest in patients receiving intravenous contrast medium within a certain period of time, and then obtains a series of images of the same anatomical position changing over time. Medical staff can analyze the obtained time-varying images to evaluate the blood flow and metabolic processes of different tissues in the region of interest. [0003] In the prior art, scanning methods for dynamic perfusion include multiple intermittent scans and single continuous scans. When multiple intermittent scans are performed, when the forward direction of the scanning table changes during the scanning process, the scanning process needs to be interrupted...
