Abstract
PURPOSE:To eliminate the influence of a crosstalk phenomenon and to improve the picture quality by correcting radiation projection data by a detector which has radiation detecting elements arranged according to information regarding scattered radiation among the radiation detecting elements, and outputting a tomographic image. CONSTITUTION:An X-ray beam 11 is projected on a body 17 to be inspected and the projection data is inputted to an X-ray detector 13. At this time, an X-ray source 12 and an X-ray detector 13 are rotated to project the X ray on the cross section of the body 17 to be inspected in respective directions. The X-ray detector 17 is constituting by arranging the X-ray detecting elements composed of scintillators and photoelectric converting elements and arranging collimators among the elements. At the time of its detection, the X-ray beam is transmitted through a collimator and enters an adjacent scintillator to cause a crosstalk phenomenon. A CPU 19, however, corrects an error in each radiation detecting element output due to the crosstalk to reconstitute an image. Thus, the influence of the crosstalk to reconstitute and image. thus, the influence of the crosstalk phenomenon is removed by the correction. so a high-resolution, excellent tomographic image is obtained.
