Abstract
A scintillation camera using the dual scintillation detector head is disclosed. The scintillation camera can include two dual scintillation detector heads, which are fixed in opposition to each other. The camera can include a dual scintillation detector head and a single scintillation detector head, which are also fixed in opposed relation to each other. The dual scintillation detector head has two scintillation detectors, which are fixed relative to each other, preferably fixed substantially at 90 degrees to each other. Each scintillation detector has a plurality of photomultiplier tubes, a collimator, and a scintillation medium. The two scintillation detectors are housed in a L-shape rigid casing,
Claims20
A scintillation camera comprising:
- a first scintillation detector head, the first scintillation detector head being a dual scintillation detector head which comprises two scintillation detectors fixed relative to each other in the form of V-shape, the two scintillation detectors providing first and second fields of view;
- a second scintillation detector head including a scintillation detector which provides a third field of view;
- and
- a mechanism for supporting the first and second scintillation detector heads in selected positions relative to each other and to the portion of a patient's body when in use, the mechanism including a first rotatable mechanism and a second rotatable mechanism,
- the first rotatable mechanism rotating the first and second scintillation detector heads about a first axis so as to maintain a spatial relationship among the first, second and third field of views,
- the second rotatable mechanism rotating the first and second scintillation detector heads about a second axis, which is different from the first axis.
