Abstract
Emission contamination data are collected in a shifted mock scan simultaneous with the collection of transmission data during a transmission scan of a patient with a collimated gamma point source, the transmission data are corrected with the emission contamination data, and the corrected transmission data are used for attenuation correction of emission data for reconstruction of an emission image of the patient. In a preferred implementation, when the point source is at a particular axial location and illuminates an axial beamwidth of 'Fz' over the gamma detector, emission contamination data are collected from the gamma detector over an axial separated region 'Fz'' having about the same axial extent but axially displaced by about half of the axial field of view (FOV).
