ABSTRACT:
A computerized tomography system and method using penetrating radiation having a radiation source for radiating penetrating radiation into the interior of a thin sliced layer portion of a subject, in a manner that it expands substantially in a fanned fashion, a detector for substantially dividing the radiation after passing through said sliced layer portion into a plurality of radiation beams diverging at a defined angle, thereby detecting the intensity of said beams, a moving unit for substantially linearly scanning each of said beams at least once in a direction transverse of said sliced layer portion, a data processing unit for reconstructing an image of said sliced layer portion on the basis of detected data delivered from said detector, and a display unit for displaying said image on the basis of the results of said reconstruction.
