Abstract
Official abstract text for this publication.
A method of multileaf collimator (MLC) leaf positioning in tracking-based adaptive radiotherapy is provided. The method includes determining a radiotherapy beam pattern by transforming a treatment beam plan into radiotherapy beam coordinates, determining a dose discrepancy between the radiotherapy beam pattern and a deliverable MLC aperture, where the dose discrepancy includes a sum of an overdose cost and an underdose cost to a treatment volume, and minimizing the dose discrepancy, where the dose discrepancy minimization provides a determined deliverable MLC aperture for the radiotherapy beam.
First claim
Opening claim text (preview).
What is claimed: 1. A method of multileaf collimator (MLC) leaf positioning in tracking-based adaptive radiotherapy, comprising: a. determining a radiotherapy beam pattern in real-time during a radiotherapy treatment beam delivery, wherein said radiotherapy beam pattern comprises transforming a treatment beam plan into radiotherapy beam coordinates; b. determining a dose discrepancy between said radiotherapy beam pattern and a deliverable MLC aperture in said real-time during sa…
