IGRT stereotassica intracranica con Brainlab Exactrac e con sistema integrato OBI: feedback dell’equipe dell’U.O.C. Di Radioterapia del P.O. Perrino di Brindisi

Abstract

The stereotactic intracranial Radiotherapy (SRS) Imaging-guided (IGRT) has increased its developments in few yearsbecause of the possibility to target lots of brain tumors also very small thanks to the new hardware tecnologies. SRSrepresents the main surgical alternative for patients with high risk complicances. This treatments requires a technology ensuring a great accuracy during X-ray exposure on the target as planned. In Perrino’s Radiotherapy there aretwo linacs with two different tecnologies ensuring the patient’s set-up accuracy (less than 1 mm). The first one is theOBI system mounted on Linac Trilogy, the second one Brainlab ExacTrac on Linac Unique. The aim of this comunication is to compare the two different system, to know which is the most appropriate ad finally to justify why a newtecnology such as Exactrac is installed on a less performing linac.
