A method and apparatus are disclosed in an EBT scanner for generating an
image from a data set collected from a subject beginning at an arbitrary
time within a scanning time interval. A sequence of temporally separated,
unfolded parallel view sinograms are generated corresponding to scans
through the subject during the scanning time interval. Data from each of
the sinograms are folded into each other such that loss of information and
image artifacts, caused by temporal separation between temporally adjacent
sinograms, are greatly reduced. An image is generated from a subset of
data taken from the folded sinograms wherein the subset of data begins at
an arbitrary time within the scanning time interval.
