... approved challenging cases, were selected for testing the new software. Key parameters, including coverage, selectivity, target volume, and doses to critical structures, were collected and statistically analysed using a t test. These parameters were compared based on the Leksell Gamma Knife (LGK) Society...

... with dose. This study focuses on deterministic effects. Case Presentations: This study compares the dose measured on phantom for the area of the pelvis and the dose measured on 3 patients with dosimeters positioned on the pelvis irradiated on Leksell Gamma Knife Perfexion/Icon. The mean dose for measurement...
