ABSTRACT:
Apparatus for producing attenuation data for compensating a radionuclide emission imaging system. A single photon emission computed tomography (SPECT) system includes a radiation source disposed across the field of view from a detector portion and offset from a diameter through the center of the field of view intersecting a center of the detector portion. The radiation source and detector thereby define an asymmetrical radiation pattern that enlarges an attenuation field of view to provide a more thorough sampling of an object in the field of view.
