Results: The results demonstrate good agreement between dose distributions obtained from the TPS and GAF film measurements, with a gamma passing rate exceeding 90% using the 3%/3 mm criteria (local) (Fig.2). This consistency validates the Monte Carlo-based Monaco TPS as a reliable method for generating data that accurately simulates EPID responses. The DL model, trained on this high-quality dataset, showed promising performance, achieving up to 99% gamma passing rate using the 3%/3 mm criteria (local) for dose distribution predictions derived from EPID grayscale images.
