ABSTRACT:
An apparatus for generating a tomographic display projects X-ray beams in a fan-shaped array through a subject in many directions within a plane, detects how much each X-ray has been absorbed by the subject, and obtains the X-ray absorption coefficient of a given point of the subject existing within the plane. X-ray absorption data are back-projected onto a reference line existing in the plane are accumulated in the pixels defining the subject under examination, are distributed onto said given point of the subject, to obtain the distribution of X-ray absorption coefficients in said plane of the subject.
