RapidArc® Radiotherapy

RapidArc is a volumetric arc therapy that delivers a precisely sculpted 3D dose distribution with a single 360-degree gantry rotation. By using an advanced algorithm that simultaneously changes the rotation speed of the gantry, shape of the treatment aperture and the delivery dose rate, treatments are delivered in less than 2 minutes in most cases. Volumetric modulated arc therapy differs from existing techniques like helical IMRT or intensity-modulated arc therapy (IMAT) because it delivers dose to the whole volume, rather than slice by slice.
