OSTI ID:5607430
In a computerized tomography (Ct) apparatus, in which a fanshaped x-ray distribution is rotated around the body of a patient , it is possible to use a ring of non-rotating detectors disposed to receive the radiation after passage through the body along a cross-sectional slice. The ring may be tilted and precessed axially so that detectors on the same side of the body as the source do not interrupt the radiation. A second source is disposed on the opposite side of the body to the first to irradiate the detectors when moved out of the radiation from the first and thereby to examine a second cross-sectional slice at the same time as the first slice.
