ABSTRACT:
In a computerized tomographic CT apparatus, X-rays penetrated from a slice of an object are computer-processed so as to reconstruct a tomographic image of the imaginary slice of the object. The CT apparatus is comprised of a table couch for supporting the object to be examined, a table couch drive control circuit for controlling a continuous transportation of the table couch along a longitudinal axis of the object, an X-ray source for irradiating fan-shaped X-rays toward the imaginary slice of the object, a detector array for detecting the fan-shaped X-rays which have penetrated throught the slice of the object. It further comprises a gantry for mounting the X-ray source and the detector array in such a manner that the X-ray source is positioned opposite from the detector array with respect to the slice of the object and for performing a relative movement between the X-ray source and the detector array in a plane which is perpendicular to the longitudinal axis of the object. The apparatus enables helical scanning to be effected by the continuous transportation of the table couch and the relative movement between them. A reconstruction control circuit is provided for processing the helically-scanned projection signals derived from the detector array so as to reconstruct a tomographic image of the slice of the object.
