Abstract: The invention relates to a patient-securing strap and to a patient-supporting device with a patient-securing strap. In one illustrative embodiment, the patient-securing strap is made mainly of plastic and has an electrical conductor made of substantially radioparent plastic, an electrical sensor which is connected to the conductor and which is made of a substantially radioparent material, and transmitter which is connected to the conductor and which is designed such that sensor signals output from the sensor to the conductor are sent to a data transmission line. In another illustrative embodiment, a patient-supporting device comprises one such patient-securing strap. The fact that the patient-securing strap is for the most part made of radioparent material means that it does not cause interfering image artefacts during an X-ray examination.

Abstract: A gating device for a radiation apparatus has at least one diaphragm plate adjustable in the beam path of a radiation transmitter, the plate having at least one guide aligned obliquely relative to the longitudinal axis of the diaphragm plate and an adjustment mechanism is attached to the diaphragm plate for moving the diaphragm plate in a manner defined by its guide to adjust the position of the plate in the beam path.
