Scatter correction using emission image estimation reconstructed from narrow energy window counts in positron emission tomography

摘要

A non-temporary storage medium that stores instructions readable and executable by an imaging workstation (18) that includes at least one electronic processor (20) for performing the image reconstruction method (100). The method comprises receiving emission imaging data (22) from the image acquisition device (12), the emission imaging data being filtered using the acquired energy passband (18). The step of filtering the emitted imaging data in a second energy passband (90), which is narrower than the acquired energy passband, produces the filtered imaging data. The filtered image data is reconstructed to generate an intermediate image. Estimate one or more scattering correction factors (SCF) from the intermediate image. Reconstruct the emission imaging data corrected by the estimated SCF to generate the reconstructed image.
