Results:

The proposed GDoTA model achieved a mean Gamma-Pass-Rate (GPR) of 94% and a median GPR of 95%, evaluated using 2%/2 mm dose difference/distance-to-agreement thresholds and a 10% dose-cutoff. GPRs ranged from 67.26% to 99.44%, as shown in Figure 1a, based on a dataset of 948 unique test cases excluded from training. Figure 2 highlights the best- and worst-case scenarios from the test set. Additionally, Figure 1b depicts results obtained using a water phantom under varying beamlet angles.
