Abstract

Highlights: An efficient low dose whole lung RT technique developed for severe COVID-19 patients. Empirical MU Calculation formula fitted from actual CT images of clinical patients. Acceptable dose distribution verified by 3D dose calculation in real patient anatomy. Abstract: This study aimed to establish an efficient planning technique for low dose whole lung treatment that can be implemented rapidly and safely. The treatment technique developed here relied only on chest radiograph and a simple empirical monitor unit calculation formula. The 3D dose calculation in real patient anatomy, including both nonCOVID and COVID-19 patients, which took into account tissue heterogeneity showed that the dose delivered to lungs had reasonable uniformity even with this simple and quick setup.
