Abstract
An emission computed tomograph provided with different types of collimators for selective use with different kinds of radionuclides. The different collimators are alternatively brought into operative position in front of the radiation detector in accordance with the kind of radionuclide being used.
Claims6
An emission computed tomograph comprising:
- means for supporting an object to be examined at a predetermined position, said object having taken therein a radionuclide that emits radiation;
- a plurality of radiation detectors so arranged as to surround said predetermined position;
- a plurality of collimator means each for use with a different kind of radionuclides and each so arranged as to surround said position;
- means for supporting said plurality of collimator means in axial alignment;
- means for causing said supporting means to be axially displaced relative to said detectors so that each of said collimator means can alternatively be brought into radial alignment with and operative relation to said detectors.
