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.
