For patients with inoperable brain metastases, whole brain radiotherapy (WBRT) has been the standard treatment for decades. Although the bladder volume was treated with mean doses of 35 Gy in the TomoTherapy group vs. 22 Gy in the LINAC group, we observed less GU toxicity after TomoTherapy.

Background and purposeThe aim of the study was to validate the use of linac-based radiosurgery in arteriovenous malformation (AVM) patients and to predict complications using an integrated logistic formula (ILF) in comparison with clinical outcomes.Patients and methodsThe results of radiosurgery in 92 AVM patients were examined. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) Abstract. Conclusion Intraprostate FMs allow for small safety margins, help decrease imaging frequency after … A megavoltage image detector is mounted opposite to the linac for treatment verification.

Um dies zu umgehen, wurde 1924 von Gustav Ising ein linac may easily observe the energy distribution on a CRT display. Article Google Scholar 4. Dzierma Y 1, Ames E, Nuesken F, Palm J, Licht N, Rübe C. Author information. The optimal beam geometry for SRT, however, has not been defined. A survival comparison based on the RTOG recursive partitioning analysis. The LINAC based virtual simulation cannot be replaced by the CT based simulation with PICTOR 3D ®, as the latter is lacking an option to verify the laser projected isocenter at the CT scanner. This makes gated treatments possible, decreasing the irradiated volumes and thus sparing healthy tissue from unnecessary radiation dose.
