The treatment machine rotates continuously around the patient, shaping the dose as it goes — fast, conformal treatment, often delivered in a couple of minutes.
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.
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.
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.
A form of volumetric arc therapy in which the machine rotates continuously around you, shaping the dose as it turns.
It achieves comparable conformality but delivers treatment faster, often in a couple of minutes, which also means less chance of movement during the session.
No. The prescribed dose is the same; it is simply delivered more efficiently.
Most sites treated with IMRT can be treated with arc therapy, and it is particularly helpful for patients who find lying still difficult.
