Motion-blurred imaging enhancement method and system

摘要

In accordance with at least some embodiments of the present disclosure, a process for enhancing a motion-blurred image is presented. The process may include receiving a plurality of projections, wherein the plurality of projections contain computed tomography (CT) data obtained in multiple motion phases. The process may include generating an enhanced multi-phase image by performing an enhancement operation based on the plurality of projections. The process may further include generating a plurality of phase-correlated images based on the plurality of projections and the enhanced multi-phase image.

1. A method to enhance a motion-blurred image, comprising:
receiving a plurality of projections, wherein the plurality of projections contain computed tomography (CT) data obtained in multiple motion phases; generating a multi-phase image based on the plurality of projections; generating an enhanced multi-phase image by performing a destreaking operation on the multi-phase image to reduce one or more motion-induced artifacts in the multi-phase image; generating a plurality of re-projections by forward-projecting the enhanced multi-phase image; generating a plurality of difference projections by comparing the plurality of projections and the plurality of re-projections; generating a plurality of phase-correlated difference images by performing a reconstruction operation based on the plurality of difference projections; and generating a plurality of phase-correlated images based on the plurality of phase-correlated difference images and the enhanced multi-phase image.
