ABSTRACT:
A device and method for acquiring Single Photon Emission Computed Tomography (SPECT) data. In particular, a method of acquiring data using a gamma camera detector with a collimator, such as a slotted, inverse fan beam collimator, for example. An example collimator that can be used for the method is one comprising: a slot substantially parallel to the axis of rotation of a SPECT scanner; a plurality of plates, each one of the plates being substantially perpendicular to the slot and also being substantially parallel to a transaxial direction of the SPECT scanner; and a detector associated with the slot and the plurality of plates such that, through any motion of the scanner, the slot, the plates and the detector retain their relative positional relationship.
