This whitepaper presents an overview of RadCalc's 3D dose algorithms, specifically the 3D Collapsed Cone and 3D Monte Carlo modules. The 3D Collapsed Cone module was introduced in version 7.0, with its clinical release occurring in November 2019, while the 3D Monte Carlo module followed in version 7.1, released in January 2020. The document details the clinical evaluations conducted to validate these algorithms, emphasizing their commitment to accuracy and reliability across various field sizes. The 3D modules integrate advanced features such as DVH protocols and automated reporting, enhancing clinical workflows. The paper also discusses the technical aspects of the algorithms, including the dose computation processes and the integration of recommendations from the American Association of Physicists in Medicine (AAPM). Furthermore, it highlights the performance metrics achieved during validation testing, demonstrating the algorithms' precision in dose verification. Overall, the whitepaper underscores RadCalc's role in ensuring effective radiation therapy treatment.
