Patent ID: 6842499

Claim:
In an electron beam tomography (EBT) scanner for scanning a subject during a scanning time interval, a method to generate an image from a data set collected from said subject beginning at an arbitrary time within said scanning time interval, said method comprising: generating a sequence of temporally separated, unfolded parallel view sinograms corresponding to scans through said subject during a scanning time interval, wherein said sequence includes a first sinogram and a last sinogram, said first and last sinograms being temporarily adjacent; folding data from a first region of view angles from each of said sinograms into a second region of view angles in a corresponding next temporally adjacent sinogram; folding data from a third region of view angles from each of said sinograms into a fourth region of view angles in a corresponding previous temporally adjacent sinogram, wherein said folding data from said first region and said folding data from said third region include combining a last half of said first sinogram with a first half of said last sinogram; and generating an image from a subset of data taken from said sinograms wherein said subset of data begins at an arbitrary time within said scanning time interval.
