Abstract: A rotating anode x-ray tube employing a generally cylindrical anode which is axially moveable relative to the cathode so that the focal spot traverses a spiral path as the anode rotates and moves axially. The axial displacement of the anode can be controlled by the temperature of the focal spot, i.e. by measuring the light emitted from the focal spot area.

Abstract: Chair apparatus specially adapted for detachable mounting on a tiltable tomography table to restrain and support a patient and his head for tomographic exposures during pneumoencephalography. The chair apparatus positions the patient's head close to the tomography table and permits multiaxial rotation of the patient about his head so that a defined isocenter in the patient's brain does not move with respect to the table. Two axes of rotation intersect the geometric center of tomographic study.
