  • Publication number: 20050035861
    Abstract: An apparatus for identification of medically related technical accessories and patients comprises a connected transponder reader and a monitoring device. The transponder reader can read out an accessory transponder attached to a medical accessory (possibly an irradiation mask) and a patient transponder. The monitoring device can acquire information read out from an accessory transponder by the transponder reader as an input signal and, dependent on this input signal, can generate an accessory identification signal. It can also acquire information read out by the transponder reader from a patient transponder as an input signal and, dependent on this input signal, can generate a patient identification signal. The apparatus can be part of a radiation therapy system. A system for identification of medically related technical accessories, comprised of a monitoring device, a transponder reader connected with the monitoring device, and an accessory transponder attached to a medical accessory is also provided.

  • Publication number: 20040056020
    Abstract: A patient positioning device for a medical treatment or examination device, in particular for an x-ray device or computed tomography device, has a heating device to warm a patient positioned on the plate. The heating device is integrated in the positioning plate of the patient positioning device, made from a fiber composite. The heating device can be a resistive heat layer formed by current-carrying conductors. The conductor system of the resistive heat layer can be x-ray transparent, for example formed of carbon fiber textile. An imaging medical examination device, in particular an x-ray device or computed tomography device has such a patient positioning device so as to enable medical examinations over a longer period of time, since chilling of the patient is prevented.

  • Patent number: 5900638
    Abstract: In a radiation protection arrangement for an x-ray diagnostics installation, at least one x-ray impenetrable strap is pivotably seated at a carrier, this being movable along a guide rail via the carrier. A brake arrangement for the carrier is provided which at least impedes movement of the carrier along the guide rail when the component of the installation on which the radiation protection arrangement is carried is adjusted in position. At least two x-ray impenetrable straps can be provided, each being pivotably seated at a carrier, whereby a formed part is provided in the region of the carrier which effects a diversion of each strap during pivoting. Each strap can be capable of being folded over and fixed in the folded-over condition, so that an opening to the examination region is produced.
