Abstract
PURPOSE: To make the resolution uniform by forming the side of a face confronting a body to be detected of a collimater in correspondence to the surface configuration of the body to be detected into a concave surface, and drawing the side part of the body to be detected of the collimater uniformly near to the surface of the body to be detected.
CONSTITUTION: One cut opening of a collimater main body 1 is formed into, for example, a substantially semi-spheroidal concave face in correspondence to the configuration of its head part, which is made into a face 1a confronting the body to be detected. Furthermore, a large number of through holes 2 of a circular, square or hexagonal configuration are formed on the columunar collimater main body 1 in parallel to the axis thereof in suitable intervals. The other surface of the collimater main body 1 is fitted to a detector DT, and further the face 1a confronting the body to be detected is drawn near to the body P to be detected so that the former covers over the latter.
