ABSTRACT:
In a gamma camera at least a part of an outer shell of lead and preferably also of the inner casing of steel surrounding a scintillation crystal is cut away on one side and is replaced with a flat but thinner plate of a material having better radiation absorbing characteristics, such as tungsten. In this way, the distance from the outside edge to the useful central measuring area is reduced on that side such that the camera can be rotated in the smallest possible circle around the head of a patient to perform a more complete and precise measurement on the majority of the head.
