ABSTRACT:
An x-ray tomography apparatus has a couch for a human subject to lie on, a cylindrical capsule to enclose part of the body, a flexible water filled bag to stabilize a portion of the human body being x-rayed, an x-ray source mounted on a rotatable frame, and an arcuate row of x-ray detector plates enclosed in a metal container filled with xenon gas. The detector plates are positioned on the rotatable frame opposite the x-ray source so that the x-rays pass through the subject and are received by the detector plates. The detector plates and x-ray source are continuously rotatable about the subject, having slip ring power and electrical connections. The couch is servo motor powered and is switched at the completion of one rotation of the rotatable frame to automatically index the subject forward. By continuous rotation of the x-ray source and detector plates and automatic indexing of the subject the continuous operation of the tomograph is possible and multiple observations on the subject can be made in a short time. The x-ray data obtained can be analyzed mathematically, e.g., by a computer program, and displayed in visual or numerical form by conventional techniques.
