We produce a computer tomography in our Centre for the treatment plan for each individual patient. For this purpose, we use the computer tomograph BRILLIANCE BIG BORE by Philips, which has been especially developed for radiotherapy. As a 16-line device, it provides crystal-clear images with brief scanning times. Thanks to the large 85 cm opening, patients can be examined while using the positioning aids, which are required for the subsequent actual treatment. High image quality and precise positioning are essential prerequisites for exactly targeted radiotherapy. The computer tomograph is located at the Singen site. Patients from Friedrichshafen need to therefore travel once to our Centre in Singen for the planning images, while the otherwise several-week-long radiation therapy is always carried out in Friedrichshafen.

There are three identical models of the linear accelerator SYNERGY from the Elekta Company that are precisely aligned with one another, available for the treatment. Two of these devices are located in Singen, one in Friedrichshafen. They produce photons in the energy levels 6, 10, and 15 megavolts (MV) and electrons in the energy levels 6, 8, 10, 12, and 15 megaelectron volts (MeV). The field formatting is done with a multileaf collimator (MLC) having 40 pairs of leaves each. With an integrated CT unit, the actual position of the patient can be checked and if required corrected directly prior to treatment (image-guided radiotherapy, IGRT).

In addition, our Centre at the Singen location also offers brachytherapy. Using the so-called afterloading method small radiation sources can be introduced into the body to release their dose there, right on target. This procedure is used, for example, for cancer of the uterus.
