RapidArc radiotherapy technology is a new approach to image-guided, intensity-modulated radiation therapy (IG-IMRT) that delivers precise treatments in shorter times than conventional IMRT.
Unlike helical IMRT treatments or other forms of radiation therapy, with RapidArc the radiation treatment being delivered to the patient can be modulated continuously throughout treatment. This means that higher doses of radiation are delivered to hit the tumor harder, and less radiation is delivered to surrounding healthy tissue.
RapidArc represents a major medical advance and is more comfortable for patients because they spend less time in their daily treatments. A fast, precise RapidArc treatment takes 80% less time. Patients can be in and out of treatment quickly and return to their daily routine. RapidArc rotates 360 degrees around the patient, enabling the very small beams with varying intensity to be aimed at the tumor from multiple angles.
