Abstract
A computer tomography apparatus has an x-ray source and a radiation detector which permit a patient to be helically scanned to obtain a tomogram of the patient. Since it is frequently desirable to obtain a conventional x-ray image (shadowgraph) of the patient as well, a method is disclosed which permits the computer used to generate the tomogram to calculate such a shadowgraph of the patient from the data acquired for the tomogram, for desired projection directions. This data is acquired, and the shadowgraph obtained, simultaneously with the exposure used to produce the tomogram.
