Abstract:
1. A non-transitory computer readable storage medium comprising instructions stored thereon that, when executed by a processor, cause the processor to carry out steps for producing an updated composite image of a subject for use in highly-constrained projection (HYPR) processing an acquired current image frame, the instructions causing the processor to carry out the steps of: a) dividing the current image frame into a plurality of spatial regions based on a location of the spatial region in the current image frame; b) determining subject motion in each of the spatial regions; and c) producing the updated composite image on a region-by-region basis by combining data in each current image frame region with other acquired image frame data in a manner determined by the subject motion detected in that region; wherein step c) includes multiplying the updated composite image by a decay constant and adding the data in the current image frame to the result of the multiplying step.
