CT SYSTEMS AND METHODS

摘要

A CT system and a method therefor. The system comprises: a delivery mechanism; a first scanning stage (A) for scanning an object under check to generate a first digital signal; a second scanning stage (B) arranged at a pre-determined distance from the first scanning stage (A) in the direction of motion of the object under check; a processing device (130) for re-establishing a CT image of the first image quality of the object under check based on the first digital signal and performing analysis on the CT image; and a control device (140) for adjusting a scanning parameter of the second scanning stage based on an analysis result of the processing device (130) so that the second scanning stage outputs a second digital signal, the processing device (130) at least re-establishing a CT image of the second image quality of the object under check based on the second digital signal, wherein the second image quality is higher than the first image quality. The system makes full use of the advantages brought by replacing the traditional slip ring technology with a distributed light source.
