ABSTRACT:
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.
