Abstract: A radiation therapy device includes an irradiation field limiting apparatus. The irradiation field limiting apparatus includes a collimator for adjusting the irradiation field, and a verification apparatus for visually verifying the irradiation field. The verification apparatus is configured such that the irradiation field is optically displayed on a patient that is positioned at a distance from the isocenter of the radiation therapy device.

Abstract: A method is disclosed for imaging within the scope of a radiation therapy. In at least one embodiment, the method includes preparing one or more contrast agent-enhanced x-ray image data records; and using the contrast agent-enhanced x-ray image data record during an irradiation planning and/or during an irradiation session.

Abstract: Use of an adaptive radiation therapy framework includes determination of a radiation beam size, radiation beam shape, and radiation beam position for delivering at least a portion of a prescribed radiation dose to a target volume based on first image data of a patient, and selection of one radiation therapy process from an available first process and second process. The first radiation therapy process comprises acquisition of two dimensional image data of the patient, determination of a position offset based on the two-dimensional image data and on the first image data, and movement of the patient based on the position offset. The second radiation therapy process comprises acquisition of three-dimensional image data of the patient, determination of a second position offset based on the three-dimensional image data and on the first image data, and movement of the patient based on the second position offset.

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.
