Title:
DISTRIBUTED LIGHT SOURCE CT IMAGE RECONSTRUCTION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/210941
Kind Code:
A1
Abstract:
Disclosed is a distributed light source CT image reconstruction method and system. The distributed light source CT image reconstruction system comprises: N segments of straight-line distributed light source, used for emitting rays; and N segments of straight-line distributed detectors, used for obtaining N segments of scanning projection data; wherein N is greater than or equal to 2. The distributed light source CT image reconstruction system uses the N segments of scanning projection data to obtain reconstructed images. The distributed light source CT image reconstruction method and system have higher spatial resolution and imaging speed, and can obtain precise reconstructed images of objects.
