Abstract
In a scintillation camera with a position calculation circuit which is indispensable to the Anger scintillation camera, the number of incident gamma rays is integrated only in the lengthwise direction of the shielding plates of a rotatable parallel plate collimator. Data on one-dimensional distribution, which are collected every time the collimator has rotated by the specified angle, are subjected to image information processing so that a picture of distribution of gamma rays may be obtained. In the presently proposed improvements in the Anger scintillation camera, a coordinate transformation circuit is added thereto, in which outputs taken from a position calculation circuit in the form of data on two-dimensional distribution are transformed into data on one-dimensional distribution and fed to an arithmetic unit for the reconstruction of an image. A collimator, which is effective for the collection of data on one-dimensional distribution, is also proposed.
