RapidArc — Volumetric Arc Therapy.

RapidArc is a form of volumetric-modulated arc therapy: the machine sweeps around you in one or more arcs, modulating the beam continuously to wrap the dose around the target.

What it is

Rather than treating from a set of fixed beam directions, RapidArc delivers IMRT-quality conformal dose as the gantry rotates — shaping intensity, aperture and rotation speed simultaneously. The result is comparable or better conformity, delivered much faster.

Why it helps

• Highly conformal dose distributions
• Markedly shorter treatment times — often a couple of minutes
• Less time on the couch means greater comfort and stability

What to expect

From the patient's side, a RapidArc session is brief and painless. It is used across many sites and, like all conformal techniques, paired with image guidance.
