Each detector on a multi-headed gamma camera can be equipped with parallel-beam (PBC) or cone-beam collimators (CBC). While PBC can provide truncation-free SPECT projection sets, CBC offers increased sensitivity in a limited field-of-view (FOV). Combined PBC and CBC SPECT data acquisition may allow increased sensitivity within CBC FOV with significantly reduced truncation artifacts in the reconstructed images. In this paper the combined CBC&PBC SPECT method is evaluated using synthetic and experimental data. We envision application of CBC&PBC SPECT in scintimammography.
