Explore the frontier of radiotherapy with Flattening Filter-Free (FFF) beams, promising swift treatment while minimizing tumor motion. But in this quest for efficiency, does compensator-based IMRT alter dose distributions? Our Monte Carlo study reveals intriguing insights: compensators reduce superficial doses but elevate peripheral doses due to scattering effects. Unravel the delicate balance between speed and precision in modern radiotherapy, shaping the future of patient care.
