Patent ID: 7705316

Claim:
A dynamic SPECT camera, comprising: an overall structure, which defines proximal and distal ends with respect to a body; a first plurality of assemblies, arranged on the overall structure, forming an array of the assemblies, each assembly comprising: a second plurality of detecting units, each detecting unit including: a detector, for detecting radioactive emissions; and a collimator, attached to the detector, at the proximal end thereof, for defining a solid collection angle δ for the detecting unit; and an assembly motion provider, configured for providing the assembly with individual assembly motion with respect to the overall structure, during the acquisition of radioactive-emission data for a tomographic image; a timing mechanism, in communication with each detector, configured for enabling time-binning of the radioactive emissions impinging upon each detector to time periods not greater than substantially 30 seconds; and a position-tracker, configured for providing information on the position and orientation of each detecting unit, with respect to the overall structure, substantially at all times, during the individual motion, the dynamic SPECT camera being configured for acquiring a tomographic reconstruction image of a region of interest of at least 15×15×15 cubic centimeters, during an acquisition time of 300 seconds or less, at a spatial resolution of at least 10×10×10 cubic millimeter or smaller voxel size.
