Tomographic apparatus for producing transverse layer images

Patent ·
OSTI ID:5029907
In an exemplary embodiment, a radiation measuring arrangement contains a radiation source as well as a radiation receiver which determines the radiation intensity behind the radiography subject. For irradiation of the radiography subject from different directions a rotating device for the measuring arrangement is present. A measured value converter calculates a layer image from the signals supplied by the radiation receiver. Between the radiation source and the radiation receiver, two hollow cylinders consisting of radiation-absorbing material having equal diameters and a common axis are arranged between which a gap for the passage of the x-ray beam is left open and into which the radiography subject can be inserted. The two hollow cylinders are adjustably mounted for relative displacement in an axial direction for the purpose of adjustment of the gap width.
