Abstract
The illustrated embodiment shows a patient supporting device for tomographic apparatus comprising two patient supports for cooperation in moving a patient through the apparatus by means of synchronously operated conveyors, the supports having a slight space therebetween to avoid interference with the scanning beam, and the confronting edges of the supports which provide the gap accommodating the scanning beam being shiftable as the housing is tilted in opposite longitudinal directions so that the gap is always in alignment with the plane of the scanning beam. Advantageously one patient support may be disengageable from the housing so as to be removable from the housing aperture and then vertically movable to a convenient level for receiving a patient.
Claims5
Tomographic apparatus for producing transverse layer images of a radiographic subject, comprising an x-ray measuring arrangement including a radiation source which produces an x-ray beam penetrating the radiographic subject and having a predetermined extent perpendicular to the layer plane, and a radiation receiver which determines the intensity of radiation behind the subject during a scanning operation, a pivot mounting for the measuring arrangement accommodating rotational movements thereof during the scanning operation, and a housing for the measuring arrangement having an opening extending therethrough for receiving a patient supporting device with a patient, characterized by the patient supporting device comprising two individual patient supports for extending into the opening of the housing from opposite sides thereof, said supports having respective conveyors lying substantially in a common plane for moving the patient longitudinally and having a small gap therebetween with a width which is at least equal to the predetermined extent of the x-ray beam corresponding to the layer thickness to be examined.
