METHOD AND DEVICE FOR COMPUTING POSITION OF RADIATION POSITION DETECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve precision in the computation of a position in a radiation position detecting device.

SOLUTION: The radiation position detecting device is provided in which light reception elements are optically coupled to two or more adjacent faces of a scintillator block having an outer shape in a roughly rectangular solid which emits light when it absorbs radiation and has at least one optically-discontinuous area. When computing a position of the radiation position detecting device so as to specify a radiation absorbed position by computing output signals of the respective reception elements of the radiation position detecting device, the output signal of the reception element at a predetermined face is weighted by a value that varies in accordance with an axial direction of the position to be specified.
