Paper Abstract

In vitro measurements have been performed to investigate the use of simultaneous multi fiber applications for laser induced interstitial thermotherapy. Because of the complex shape of coagulation zones produced with more than one applicator, a measuring technique was developed to determine the necrotic volume regardless of its form. With this method it was possible to vary the mutual fiber distance for a multi fiber procedure with two scattering applicators. It was found that this method is highly efficient because treatment time is reduced while at the same time necrotic volumes are 2.5-fold larger than those of a comparable single fiber application. It is stated that this kind of procedure shows a critical fiber distance where an overlap of coagulation volumes is not certain and should therefore be avoided. Fiber separation below the critical do not require extremely precise punctures because variations of a few millimeters do not change the necrotic volume significantly.
