Phantom cases of interest. (a) Irradiation using Eclipse AAA with high dosimetric leaf gap (91st percentile) that overestimated the dose delivered (purple) compared to film measurement (green) by ~ 7%. The institution overestimated the dose on a second attempt three months later using the same beam model. (b) Irradiation using Eclipse AAA with very low DLG (1st percentile) and MLC transmission (2.5th percentile), that underestimated the dose delivered (red) compared to film measurement (green) by 5% on average. A second attempt was made after adjusting the DLG (from 0.06 cm to 0.125 cm), which improved the accuracy substantially and resulted in a passing audit.
