Problems solved by technology

[0004] However, the following problems exist in the existing correction data acquisition methods: for different collimation width scanning conditions of a specific system, the coefficients of calibration correction are not the same, which makes the calibration correction need to be performed separately under different collimation widths , which affects the efficiency of calibration and increases the number of scans

Abstract

This application discloses a system for image data processing. The system includes a scanner, one or more storage devices, and at least one processor. When the at least one processor executes the set of instructions, the at least one processor is configured to cause the system to: acquire a relationship between a scattered radiation intensity and a collimation width; obtain a target collimation width of the collimator; determine a target correction coefficient based on the target collimation width and the relationship between the correction coefficient and the collimation width.

Description

technical field [0001] The present application relates to a computerized tomography (CT) image data processing system, in particular to a system for modifying scanned image data based on the collimation width of the scanning process. Background technique [0002] A collimator is an input component of a CT system. A collimator is positioned between the X-ray source and the object being scanned (eg, a patient) to control the scanning process (eg, scan area and slice thickness). To improve image quality, image data collected in a CT system can be modified prior to image reconstruction. The modification of the image data is related to the characteristics of the collimator, eg collimation width. Accordingly, there is a need to develop systems and methods for modifying image data based on collimation width. [0003] When the CT system is used, it is necessary to perform calibration correction on the scan data to ensure the accuracy of the CT value in the reconstructed image. I...
