METHOD FOR MOVEMENT COMPENSATION OF IMAGE DATA

摘要

According to an exemplary embodiment a method for movement compensation of image data of an object of interest comprises receiving projection data, receiving motion vector field data, and dividing the motion vector field data into a number of layers of motion vector field data. Furthermore, the method comprises generating motion compensated projection data by projecting at least one of the number of layered motion vector field data onto the projection data and applying a two dimensional motion compensation on the projection, and generating image data of at least one voxel by back-projecting the movement compensated projection data.
