  • Three-dimensional time-of-flight pet with coarse angular and slice rebinning
    Patent number: 7897926
    Abstract: In a time-of-flight positron emission tomography (TOF-PET) imaging method, three-dimensional time-of-flight line-of-response (TOF-LOR) data are acquired. Each TOF-LOR corresponds to a line-of-response with time-of-flight spatial localization. The TOF-LOR data are slice-binned into a plurality of two-dimensional TOF-LOR data sets based on the time-of-flight spatial localization. At least some of the slice-binned TOF-LOR data correspond to lines of response that are oblique to the two-dimensional data sets. The TOF-LOR data are coarsely angularly rebinned to a plurality of coarse angular bins each having an angular span of at least about 10°. The coarsely angularly binned TOF-LOR data are reconstructed to produce the image slice.
