Abstract:
An imaging system for acquiring imaging data of an object positioned about an axis to form a SPECT image, said system comprising:first and second gamma ray detectors;a first pair of rings, oriented substantially perpendicular to and disposed so as to be rotatable about the axis;a second pair of rings, oriented substantially perpendicular to and disposed so as to be rotatable about said axis;means for coupling said first detector to said first pair of rings, with an imaging surface of the first detector facing the axis and the first detector disposed between said rings;means for coupling said second detector to said second pair of rings, with an imaging surface of the second detector facing the axis and the second detector disposed between said rings; andmeans for independently rotating said first pair of rings to adjust the angular displacement, about the axis, between said first and second detectors to a predetermined magnitude.
