ABSTRACT:
An emission CT apparatus for detecting, in positions around an examinee, radiation from radioactive nuclides introduced into the examinee and having accumulated in a site of concern, in order to acquire density distribution images (sectional images) of the nuclides in sections of the site of concern. The apparatus comprises a gamma camera for detecting the radiation, a rotary device for revolving the gamma camera stepwise round the examinee, an image memory for collecting image data from the gamma camera for respective time frames defined by dividing a period of time for which the gamma camera stands still at each angular position, a computing unit for determining a center of gravity of the image data in each time frame, an adder for adding image data, with the center of gravity brought into agreement, in each time frame, thereby to obtain image data in a direction of each angular position (view), and an image reconstruct unit for reconstructing an image based on the image data of each view corrected.
