IMAGE RECONSTRUCTION METHOD FOR COLLIMATOR AND DETECTOR BASED MEDICAL IMAGING SYSTEMS

机译:基于采集器和检测器的医学成像系统的图像重建方法

摘要

According to various embodiments, the present disclosure provides a method of imaging reconstruction. The method of imaging reconstruction includes providing a target object, a detector, and a mask disposed between the target object and the detector; acquiring a measured image of the target object by the detector; providing an estimated image of the target object; partitioning the mask into multiple regions; for each of the regions, deriving a forward projection from the estimated image of the target object and the respective region, thereby acquiring multiple forward projections; comparing the measured image of the target object with the forward projections; and updating the estimated image of the target object based on a result of the comparing.
