AI Technical Summary

Technical Problem

During PET or SPECT scans, motion artifacts appear in the reconstructed images due to time asynchrony between the PET or SPECT device and the external motion monitoring device. Existing technologies struggle to effectively solve the time synchronization problem.

Method used

By acquiring scan data and external motion information, the distribution centroid signal is determined, and the distribution centroid signal is corrected according to the motion. The time consistency between the scan data and the external motion information is detected, and the MCCOD signal is used for correction to ensure time synchronization.

Benefits of technology

It achieves time synchronization between PET or SPECT scan data and external motion information, reduces motion artifacts, and improves the accuracy and efficiency of image reconstruction.

Abstract

This application relates to a time consistency detection method, apparatus, computer device, and computer-readable storage medium. The method includes: acquiring scan data to be detected and external motion information; determining a centroid signal corresponding to the scan data; determining a motion-corrected centroid signal corresponding to the centroid signal based on the scan data and the external motion information; and determining the time consistency between the scan data and the external motion information based on the motion-corrected centroid signal. This method can utilize MCCOD signals to detect the time consistency between scan data and external motion information, thereby ensuring time synchronization between the scan data and the external motion information.
