For this reason, no specific online imaging or tracking device was required.ConclusionThese are first dosimetric results of a randomized phase III trial recently started in our institution. For linacs, better dose distribution was obtained on the target rather than for normal tissues, even though no specific side effects were reported. In addition, data suggested a better comfort for the patient for linac-based therapy, due to the shorter treatment time and the non-invasive immobilization system. Dosimetric data for the patients treated according to this protocol suggest a substantial balance between Gamma Knife and Linac EDGE treatments.Figure1 from left to right: target dimension, PCI, GI and HI in the two study arms56
