Comparison of dosimetric characteristics of 120-leaf and 80-leaf multi-leaf collimators in a Varian linear accelerator for a 6-MV photon beam.


In this study, the dosimetric characteristics of multileaf collimators (MLCs) with 120 leaves and 80 leaves were evaluated. The dose rate, percentage depth dose, surface dose, dose in the build-up region, beam profile, flatness, symmetry, and penumbra width were measured by three field-defining methods: (1) "Jaw only", (2) "MLC only", and (3) "MLC + Jaw… (More)
