On-Board Imager® (OBI) and Cone-Beam Computed Tomography (CBCT)
Our radiation oncologists use OBI technology to image your tumour before therapy, as soon as you’re on the treatment table, ensuring that you and the tumour are at the same position as originally planned.
OBI employs three different methods of imaging.
One of these methods, the cone-beam computed tomography (CBCT), takes 3D, 360° CT scans of the body while the patient lays on the treatment couch.
RapidArc ® Radiotherapy Technology
RapidArc® radiotherapy technology, developed by Varian Medical Systems, is an extremely fast and precise form of image-guided, intensity-modulated radiation therapy (IMRT). Image guidance improves tumour targeting and IMRT shapes the radiation dose so that it conforms closely to the 3D shape of the tumour. This means more dose to the tumour and potentially less to surrounding healthy tissue.
