81 Application of the TRS-483 correction factors on output ratios measurements for 8 detectors in stereotactic radiosurgery with cones

Introduction. The purpose of this work is to assess correction factors performances from TRS-483 [ [1] International Atomic Energy Agency. Dosimetrie of small static fields used in external beam radiotherapy. Rapport n483, 211 pages, Vienne; 2017.
