Level 3 Audit

Gamma Gurus' Level 3 Dosimetry Audits are designed to be an end-to-end test of a facility’s treatment planning and delivery processes. The facility will create multiple plans for a thorax phantom and then measurements will be made with a compact thimble chamber during treatment delivery, comparing the expected dose to the measured dose.

Plans have been selected to evaluate the following concepts: SSD setup, single beam isocentric setup, field size factors, heterogeneity correction, couch attenuation, IMRT, VMAT, multitarget, and SABR.

Gamma Gurus is a NATA accredited organisation and can provide your department with a range of dosimetry audits in accordance with ISO/IEC:17025
