DEVICE FOR X-RAY BRACHYTHERAPY, AND METHOD FOR POSITIONING A PROBE INTRODUCED INTO A BODY FOR X-RAY BRACHYTHERAPY

摘要

In a method and a device for x-ray brachytherapy, a probe is inserted into the interior of the body of a subject, the probe carrying at its distal end an x-ray source that radiates x-rays into an exposure area in the body of the subject outside of the probe. The probe also contains an x-ray array that generates an ultrasound image representing at least a portion of the exposure area. A display device displays the ultrasound image to allow identification of the exposure area in the ultrasound image.
