摘要

Device for the x-ray - brachytherapy with a into the interior of a body (4), which can be inserted probe (6), which at its distal end has an x-ray source (8), the x-rays (14) into an irradiation field (18) outside of the probe (6), and with a plurality of markers (36) which, in an image generated with an imaging means can be seen, and which, in or on the probe (6) in a known spatial relationship to the irradiation field (18) are arranged, whereby from this known spatial relationship with the aid of the imaging device, a reconstruction of the position of the irradiation zone (18) in the image.
