Radiotherapy is a treatment that uses high-energy photons, which are small parts of atoms, to kill cancer cells. This technique involves delivering radiation to a specific area of the body to destroy the tumour. For this purpose, the linear accelerator (LINAC) is used to produce radiation that targets the tumour in daily sessions of just a few minutes.
Intelligent dose calculation systems deliver high-precision beams. Radiotherapists work closely with dosimetrists and physicists to develop radiotherapy treatment plans and work out the radiation doses that will be delivered to patients. Each stage of treatment is subject to rigorous quality assurance.
On-board imaging (OBI) techniques and cone beam computed tomography (CBCT) enable technicians to ensure the reproducibility of radiation doses from one session to the next. In addition to offering external radiotherapy techniques, the centre also provides patients with access to other forms of radiotherapy developed within Swiss Medical Network. For example, intraoperative radiotherapy (IORT) is performed at Clinique de Genolier for early-stage breast cancer. Moreover, contact radiotherapy for rectal cancer is available at Clinique de Genolier and Centre d'Oncologie des Eaux-Vives. This technique delivers high-precision radiotherapy to the rectal cancer via the Papillon system by Ariane Medical Systems. It can also be combined with percutaneous radiotherapy and chemotherapy, if necessary.
