Claim Text:
1. An imaging method comprising: receiving radiation transmission image data of a subject situated in an examination region acquired with a tomographic imaging modality; defining a field-of-view (FoV) with a voxel grid in a trans-axial direction; determining the subject's maximum trans-axial extents; generating an extended FoV by extending the voxel grid of the FoV to at least one extended region outside the FoV that encompasses at least the determined maximum trans-axial extents and attenuation in the trans-axial direction; reconstructing the acquired radiation transmission data into an attenuation map of the extended FoV; receiving nuclear image data of the subject acquired with a radiation emission imaging modality; wherein the radiation transmission image data from the first imaging modality is acquired concurrently or in close temporal proximity with the nuclear image data of the radiation emission imaging modality; and reconstructing the nuclear image data including using the attenuation map.
