ABSTRACT:
An apparatus and method for nuclear medical imaging (e.g., SPECT imaging) using cone-beam or multifocal collimators is disclosed. According to the embodiment of the invention, the detector/collimator is tilted in a fore-aft direction, with the tilt angle varying as a function of the orbital position of the detector assembly. The patient pallet may also be moved longitudinally as a function of the tilt angle (i.e., as a function of the orbital position) for optimal image quality.
