Abstract:
1. A nuclear medical imaging apparatus, comprising: a patient support pallet; a nuclear medical imaging head supported for orbital movement relative to the patient support pallet about an orbital axis, the imaging head including a detector and a non-parallel hole collimator arranged parallel to each other, the imaging head being configured such that the detector and the collimator can be tilted in a longitudinal, fore/aft direction by a tilt angle φ; and a control system that is configured to control the orbital movement of the imaging head about said patient support pallet over a predetermined range of orbital angular positions θ and to control the tilt angle φ so as to vary as a function of the orbital angular position θ of the imaging head, in such manner that for each orbital position being imaged, nuclear emission rays are detected that are perpendicular to said orbital axis.
