Emission ct apparatus

Abstract

Abstract PURPOSE:To obtain the image of a photographing target portion with a high resolution by enlarging and reconfiguring the image of the photographing target portion in an object to be examined by using part of the data of a radiation from the object that are collected by a detector. CONSTITUTION:The data of a radiation from a radioisotope given into an object to be examined are collected by a detector 2 revolving around the object and the image of a photographing target portion is enlarged and reconfigured by an image enlarging and reconfiguring unit 4 by using part of the whole collected data. Processing data specifying means 10 has a memory 12 storing the visual field range of the detector 2 necessary for collecting the data of the photographing target portion for every revolving angle of the detector 2. The means 10 specifies the data within the visual field range of the detector 2 necessary for collecting the data of the photographing target portion and within the visual field range changed for every revolving angle of the detector 2 by the revolving angle information of the detector 2 and the position information of the photographing target portion to the image enlarging and reconfiguring unit 4 as processing data.
