Abstract: A multipurpose apparatus for making normal or tomographic investigations by means of a gamma camera. The apparatus comprises an image detector head mounted on a gantry supported by a column running on guides, which detector head is set in motion in a plane determined by said guides and said column to describe a closed curve trajectory about a supported bed on which the patient is accommodated. The detector head can also rotate about its own support axis, such rotation being such as to allow the head to maintain the detection surface at all times tangential to said trajectory.

Abstract: This invention relates to a gamma camera tomography apparatus. According to the invention, an apparatus for making tomographic or normal surveys by means of a gamma camera comprises a base frame, which rotatably supports a discoidal member of horizontal axis, on which an articulation support for a survey head containing a gamma camera is radially mobile.Said discoidal member comprises a central hole, through which the body of a patient supported on a sliding bed is able to pass. There are provided motor means for rotating the discoidal member for radially moving the head support.
