摘要
Applicant presents an improved manner of modeling and calculating the tongue-and-groove effect in multi-leaf collimators in treatment planning systems and processes. The method is based on subtracting an individualized profile area that is determined for each individual model of MLC. The method also includes how to easily obtain the shape of this non-constant profile based on the tests. The method provides better accuracy, particularly for plans using small MLC gaps.
