A gamma camera has a base fixed to a frame along a substantially horizontal axis of rotation called the axis of rotation of the gamma camera, bearing at least one arm that is substantially parallel to the axis of rotation and provided, at its free end, with a detector head. The arm is rotationally movable about an axis called an axis of angulation of the detector head, substantially parallel to the axis of rotation of the gamma camera, and passing through the position at which said arm is fixed to the base. In one embodiment, the axis of angulation of the detector head is offset with respect to an axis of orientation of the head toward the head detection surface and passes substantially through the center of gravity formed by the arm and the head. In another embodiment, the end of the arm holding the head has a two-finger gripping piece with bevelled ends.

In order to change from antero-posterior examination to lateral examination with an osteodensimeter, the yoke carrying the X-ray tube and the radiation detector of this apparatus is moved laterally. Changeover of the entire assembly is enabled when this lateral translation comes into abutment. When changeover is complete, the return transverse translation is performed. Prior to performing lateral examination, the bed on which the patient to be examined is lying is itself raised. It is shown that this dynamic configuration makes it possible to keep the position of the X-ray tube relative to the detector fixed and as adjusted by construction.

Method of changing between antero-posterior examination and lateral

A scintographic installation includes a patient-supporting table (10) and a stand (11) whose support column (19) is moveable along an axis OX. The invention lies in the fact that the table (10) is mounted on a rail (15) which is capable of taking up different angular positions about an axis parallel to the axis OZ. In a first position the rail (15) is parallel to OY and the stand (11) is in a position suitable for performing tomographic examination. In a second position, the rail (15) is parallel to the axis OX and the stand (11) is a position suitable for examining the entire body by displacement of the column (19), i.e. without displacing the bed (12).
