A nuclear medical diagnostic apparatus for detecting gamma rays emitted from the radio isotope (RI) administered to a subject, to generate images showing the functions of the subject, such as metabolism. In the nuclear medical diagnostic apparatus, at least one detector is attached to a rotating ring and located inside the ring. The apparatus can therefore be modified as a one-detector type to a four-detector type. It can easily be graded up from a one-detector type to any one of the other types including the four-detector type. Further, the image-generating mode can be freely changed. Moreover, the apparatus can be small and light.

Nuclear medicine diagnostic apparatus

A scintillation camera includes a plurality of detectors mounted on the camera and arranged to provide an opening for allowing the insertion of an object for examination such as a human being and for radiographing a tomographic image, a plurality of collimators each of which is attached to the front of the corresponding detectors for collimating X-rays radiating from the object for examination, and an exchanger for the collimators, the exchanger including a carrier and a holding device for holding the collimators in a swingable manner in any direction within a certain range by use of a mechanism such as a spherical bearing.
