  • Pneumoencephalography chair
    Patent number: 4071231
    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.
