ABSTRACT:
Disclosed are x-ray machines using fan-beams of x-rays to examine sectional slices of patients and to form detailed x-ray pictures of such slices, and methods of so examining patient slices. A source of a fan-beam of x-radiation, and a system detecting the radiation after it passes through a slice of the patient, rotate around the patient.
