1 Film QA Pixels Exceeding Gamma = 1% Courtesy of Chester Ramsey

2 Scandidos Delta 4 A cylinder-shaped plastic phantom with 2 imbedded orthogonal crossing detector planes diode detectors Dose is recorded in 2 planes and a 3D dose is reconstructed for comparison with the QA plan.

3 1386 diode detectors arranged in cylindrical geometry Measure entrance and exit dose Result is a composite dose for entire delivery Arc Check – Sun Nuclear

4 IBA MatriXX 2D array of 1020 ion chambers. The cumulative dose is measured using the MatriXX placed in the MULTICube phantom. 2D dose distribution can be measured for coronal and sagittal planes.
