Theodor-Kutzer-Ufer 1-3 Intraoperative Radiation TherapyDuring Intraoperative Radiation Therapy a radiation unit mounted on a support is used to generate a 50 KV x-ray beam.
With this mobile intraoperative radiation unit (Intrabeam, ZEISS Corporation, Germany ) a highly effective radiation
dose can be applied to the tumor bed during operation while reducing the risk to nearby healthy tissue. The Intrabeam System is equipped with a special,
spherical applicator that allows for a homogenous dose distribution along its surface. This lets the surgeon precisely apply the previously calculated
dosage during the operation at the desired depth.
The advantage of intraoperative radiotherapy lies in the high degree of precision with which the beam can be applied. During the operation,
once the surgeon has removed as much of the tumor as possible, the applicator is positioned exactly in the tumor bed, and a pre-selected radiation dosage is applied
over 20 to 25 minutes.The radiation unit and applicator are then removed and the operation completed as normal.
