Purpose: Monaco treatment planning system (TPS) version 5. 1 uses a Monte-Carlo (MC)-based dose calculation engine. The aim of this study is to verify and compare the Monaco-based dose calculations with both Pinnacle3 collapsed cone convolution superposition (CCCS) and Eclipse anisotropic analytical algorithm (AAA) calculations. https://www.chiggate.com/shades-eq-09gi-hamptons-supply/
