WebLateral penumbra of multileaf collimator plays an important role in radiotherapy treatment planning. Growing evidence has revealed that, for a single-focused multileaf collimator, lateral penumbra width is leaf position dependent and largely attributed to the leaf end shape. In our study, an analytical method for leaf end induced lateral penumbra modelling … Web6. jún 2024 · INTRODUCTION. Recently, the boron neutron capture therapy (BNCT) technique has gained acceptance as a method of treatment in the field of radiation therapy [1–3].An alpha particle with high linear energy transfer (LET) is generated through a reaction between a neutron and a boron particle and can cause massive damage to a tumor cell.
