Optimization of multileaf collimator leaf sequences based on multiple algorithms

摘要

To investigate the efficacy of Gahin, Bortfeld and Siochi leaf sequencing algorithm, a leaf sequencing optimization program that compares the results of typical clinical cases is presented. The output of this program is the number of segment and the total number of monitor unit of each clinical case based on the aforementioned three algorithms. Numerical results of each case are analyzed and tested by the movement of multileaf collimator. It shows that this comparison program is effective in clinical.
