Abstract
Systems and methods of generating an attenuation map are disclosed. Computed tomography (CT) scan data for a CT scan including an imaging component is obtained. The CT scan data comprises a plurality of voxels each having a scanned CT value. A material in each voxel of the plurality of voxels is identified by comparing the scanned CT value for the voxel with predetermined CT values for a plurality of materials and a voxel attenuation value for each voxel is determined based on the predetermined CT value for the identified material. An attenuation map including the determined voxel attenuation value for each voxel is generated. The attenuation map is configured for attenuation correction of an imaging modality including the imaging component with a field of view of the imaging modality.
