In radiation oncology treatment planning techniques and outcomes can differ from one institution to the next. With knowledge-based planning (KBP) the experience of larger institutions could help smaller institutions who may not have the opportunity to encounter certain types of cancer cases. However, this scenario is only true if the KBP software is consistent with its algorithmic output. Varian's KBP software called Rapid Plan (RP) will be analyzed for algorithmic consistency. This study investigates the validity and consistency of RP models from two different radiation oncology institutions, and compare data to determine RP quality, and consistency when planning prostate cancer cases.
