Scanning method based on prior information and medical scanning system

Abstract

The invention relates to a scanning method based on prior information and a medical scanning system. The scanning method based on prior information comprises the steps of obtaining the information data of a scanning object, obtaining the prior information corresponding to the scanning object from a prior information database according to the information data of the scanning object, and determining actual scanning parameters and actual reconstruction parameters of the scanned object according to the prior information, scanning the scanned object according to the actual scanning parameters to obtain actual scanning data, and performing image reconstruction on the actual scanning data of the scanned object according to the actual reconstruction parameters. By means of the method, the problem that in the prior art, scanning parameters obtained by manufacturers through index or phantom experiments cannot be completely suitable for scanning objects of different body types and different clinical scenes, and consequently the scanning dosage cannot be reduced in a targeted mode is solved, and the scanning parameters of the scanning objects are determined through prior information related to the scanning objects; and therefore, the scanning dose of each scanning object is reduced in a targeted manner.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a scanning method and a medical scanning system based on prior information. Background technique [0002] Computed Tomography (abbreviated as CT) is a relatively advanced clinical examination imaging technology in the field of medical imaging. Through the CT scanning system, doctors can clearly observe the body tissue conditions that are difficult to show on ordinary X-ray films, such as cerebral hemorrhage or various small tumors, etc., which significantly improves the level of clinical diagnosis. CT scanning equipment uses precisely collimated X-ray beams to scan sections one by one around a certain part of the human body together with highly sensitive detectors. According to the difference in the absorption and transmittance of X-ray beams by different tissues of the human body, the X-ray beams passing through the human body are measured by the detector, and the ac...
