MR imaging is well known for its exquisite soft tissue contrast. State of the art linear accelerators have Cone Beam CT (CBCT) image guidance, which suffers from low contrast, and CT images cannot be captured concurrently with the beam delivery. The Aurora RT™ combines high quality MR images with a 6 MV linear accelerator. The machine is designed to provide excellent images prior to treatment for accurate patient alignment, as well as real time MR imaging during beam delivery to allow advance gating or tumour tracking features. These also make the Aurora RT™ perfectly suited for adaptive radiotherapy.
