Clinical Specialties


Radiation Oncology Centres, Sydney Adventist HospitalRadiation Oncology Centres (formerly Radiation Oncology Institute) is located in the San Integrated Cancer Centre near the Reception on Level 2. This is is one of two treatment centres owned and operated by a dedicated team of cancer specialists, with the second centre located in Gosford.

ROC features a brand new TomotherapyEdge machine plus two new Varian Silhouette linear accelerators. Our Varian linacs have the latest state of the art capabilities to deliver the most clinically advanced treatments in radiotherapy today.

TomotherapyEdge is the next generation radiation therapy machine providing the most accurate and broadest range of treatment to date. Tomotherapy allows continuous delivery of radiation from all angles. Coupled with precise beam modulation and superior beam definition, this enables us to achieve unparalleled conformity to the tumour and maximize sparing of surrounding and enclosed healthy tissues. In doing so, we can increase effectiveness of treatment and reduce side effects which helps improve quality of life. This means that with head and neck cancers for example, there can be reduced complications like dry mouth from effects to the salivary glands. It also allows us to treat a previously irradiated area.

ROC also has RayStation, the most advanced planning system available in the world and only available at ROC in Australia.

RayStation allows doctors to significantly reduce the time to develop the treatment plan. It includes a unique ability to track changes in the radiation dose in response to patient changes as a result of treatment, e.g. weight loss, and then rapidly modify the treatment plan during a treatment course in order to maintain the best treatment. It combines with any type of imaging like PET scans, MRIs, CT scans and bone scans to allow for more precise targeting of tumours.

The Tomotherapy/Raystation combination is designed for one purpose only - advanced radiation treatments. Traditionally, static beams from a Linac (linear accelerator) are delivered to the tumor from a limited number of angles. Tomotherapy allows continuous delivery of radiation via thousands of beamlets, which target the tumor and minimise organ risk.

ROC provides a comprehensive suite of clinical treatments including:

  • 3D Conformal Radiotherapy
  • Intensity Modulated Radiotherapy (IMRT)
  • Image Guided Radiotherapy (IGRT)
  • VMAT and RapidArc: Volumetric Modulated Arc Therapy (VMAT)
  • Low Dose Rate Brachytherapy (LDR)
  • High Dose Rate Brachytherapy (HDR)
  • Stereotactic Body Radiation Therapy (SBRT)


Radiation Oncology Centres is located on Level 2 of the Clark Tower. The Centre is accessed via the main traffic lights on Fox Valley Road. We recommend you park in the main (multi-deck) car park - P1. Some designated parking is available for radiotherapy patients on Level 2 of P1.
