Abstract
Two or more stimulable phosphor sheets are exposed to a radiation passing through an object under conditions different from one another, and radiation images of the object at least partially different from one another are recorded on the stimulable phosphor sheets. The stimulable phosphor sheets are then scanned with stimulating rays to convert the radiation images into light, which is photoelectrically read out and converted into digital image signals. The digital image signals are subjected to a subtraction processing with respect to the corresponding picture elements of the images, thereby to obtain a signal for forming an image of a specific structure of the object.
