Patent ID: 8885907

Claim:
A method for reconstructing a series of image frames for display at a predetermined frame rate, from a stream of projection data from a detector of a tomographic emission scanner, the method comprising: receiving a continuous stream of projection information generated from tomographic emission detectors; dividing the projection information into a sequence of time-dependent segments, and, for a current frame, associating with it projection information from at least one segment; reconstructing an image for the current frame, the reconstructing of the image comprising: accumulating projection information from the at least one segment associated with the current image frame; comparing the accumulated projection information to estimated projection information that has been forward projected from an estimated image from a prior frame, and generating projection information error, the estimated image for the prior frame having been reconstructed based at least in part on one or more prior segments of projection information that does not include the projection data from the at least one segment associated with the current image; back projecting the projection information error to create an error image; and combining the error image and the estimated image from the prior frame to generate an estimated image for the current frame; and displaying the estimated image for the current time frame.
