IPC分类号： A61N5/10
摘要： Verifying radiation dose delivery in a radiation therapy system includes: generating (S3) radiation dose distribution images of measured radiation beams; mapping and storing (S4) the dose distribution images as data points of a first data structure, the first data structure having, as dimensions, positional information and radiation dose information of the measured radiation beams; comparing (S5) the data points of the first data structure with corresponding data points of a second data structure using a three-dimensional (3D) gamma portal dose distribution algorithm, the second data structure having, as dimensions, positional information and radiation dose information of predicted radiation beams; determining differences between the measured and predicted radiation beams based on a result of the comparison; and evaluating (S8) radiation dose delivery based on the determined differences.
