This document discusses intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) optimization algorithms, including direct machine parameter optimization (DVO), leaf motion calculation (LMC), progressive gradient optimization (PGO), and multi-resolution dose calculation (MRDC). It emphasizes that theoretical physicists developing these algorithms have revolutionized the field of radiation oncology by enabling more conformal radiation treatments.
