FFF Technology

Flattening Free Filter Mode technology or FFF has dose rates of 2,400 (as compared to 600 or below in filtered beam). Thus, the beam gets reduced by one third to one fourth. This offers patient comfort and minimises the effect of movement during treatment or respiration.


With FFF technology, the treatment time is reduced from minutes to seconds. The high doses are delivered with precision and accuracy and does not affect the normal tissues. This reduces the chances of secondary cancers and optimises medical outcomes. Higher dose rates also have definite clinical benefits in organ motion management. For example, larger dose fractions can be delivered in a single holding of breath. This technology can be used to treat prostate cancer, lung cancer, liver cancer, brain tumour, head and neck tumour and for any other metastatic site.
