Twin-detector type scintillation camera apparatus capable of setting detecting directions of detectors in desired direction

A twin-detector type scintillation camera apparatus, comprising:

• a pair of detectors disposed in opposition to each other with a table for supporting an object under examination being interposed therebetween to detect radioactive rays emitted from said object;
• a rotatable frame disposed in a plane extending in a direction orthogonal to a longitudinal axis of said table for supporting said paired detectors at one side thereof;
• a translation mechanism mounted on said rotatable frame for moving said detectors in parallel with each other in a plane extending orthogonally to said longitudinal axis of said object supporting table while maintaining parallelism between said detectors;
• an approaching mechanism for moving said pair of detectors in directions orthogonal to the directions in which said detectors are moved in parallel with each other by said translation mechanism;
• and
• rotating means for driving rotationally each of said detectors, respectively, by a predetermined angular distance from given positions of said detectors, respectively.
