A<unk>  is an imaging device, used to capture emission from radiopharmaceuticals in nuclear medicine. The image is created by physically moving a radiation detector over the surface of a radioactive patient. It has become obsolete in medical imaging, largely replaced by the gamma camera since the late 1960s.
