1. A method for evaluating radiation dose delivery to a target, comprising:
generating a radiation dose distribution image based on radiation delivered according to a treatment plan; comparing the generated radiation dose distribution image with a corresponding predicted radiation dose distribution image, the comparing including comparing points in the generated radiation dose distribution image with corresponding points in the predicted radiation dose distribution image; evaluating the compared points using different evaluation criteria; and determining whether dose delivery is acceptable based on a result of the evaluation.
