Method and apparatus for optimization of collimator angles in intensity modulated radiation therapy treatment |
摘要 |
A method and apparatus to determine an optimum collimator angle of a multi-leaf collimator having an opening and multiple leaf pairs for closing portions of the opening to form a radiation beam arrangement having multiple radiation beam segments. The method and apparatus include application of a cost function to determine a collimator angle which provides for delivery efficiency and target conformity. The user can preferentially either selectively enhance delivery efficiency of the radiation beam arrangement, reducing a number of radiation beam segments and reducing a number of radiation beam monitor units required for delivery of the desired prescription, or selectively enhance conformity of the radiation beam arrangement to a target shape. The optimum collimator angle is then used for delivery of an optimized radiation beam arrangement to a patient by a radiation delivery device.
