ABSTRACT:
In a computed tomographic method in which a tomographic image of an object is composed from many X-ray projection distribution images obtained by exposing a section of the object to X-rays in many different directions, the X-ray projection distribution images obtained by respective exposures to X-rays are once stored at positions different from one another on a stimulable phosphor sheet, the stimulable phosphor sheet is then scanned with a stimulating ray, and a tomographic image of the object is composed by use of electric signals obtained by photoelectrically reading out light emitted from the stimulable phosphor sheet upon stimulation thereof. The stimulable phosphor sheet and an X-ray source are integrally rotated around the object, while the stimulable phosphor sheet is moved approximately at right angles to the plane formed by the rotation thereof.
