Apparatus and methods for three dimensional image reconstruction from data
acquired in a positron emission tomograph (PET). This invention uses a parallel/pipelined
architecture for processing the acquired data as it is acquired from the scanner.
The asynchronously acquired data is synchronously stepped through the stages performing
histogramming, normalization, transmission/attenuation, Mu image reconstruction,
attenuation correction, rebinning, image reconstruction, scatter correction, and
image display.
