Abstract

A ray measuring arrangement for scanning of a selected transverse section is associated with a compensating body of tissue equivalent material having a patient-receiving through-aperture of size such that a patient may be moved into and through such aperture by means of motor driven patient supports at opposite longitudinal sides of the aperture. For cranial examination, a holder ring of tissue equivalent material is supported for longitudinal movement within the aperture of the compensating body, the holder having a position adjacent a patient support so that the motor drive can transport the patient longitudinally until the patient's head rests on an elastic contouring member of the holder. The contouring member is then filled with a suitable liquid so as to closely conform with the contour of the patient's head. Thereupon, further motorized drive of the patient support moves the patient and the holder longitudinally until the patient's head is correctly located for examination. The reverse process is followed so as to remove the patient from the operating position by the motorized drive, the patient thereby smoothly and comfortably being returned to the initial position on the p…
