Radiation Therapy treatments available at SCGH

SCGH Radiation Oncology is equipped with Varian TrueBeam® advanced medical linear accelerators, designed to treat every area of the body with enhanced speed and accuracy.

We are dedicated to staying abreast with the latest technology and research and offer a wide range of specialist treatment techniques. Your Radiation Oncologist will discuss your treatment options with you.


Intensity Modulated Radiation Therapy (IMRT) is a highly conformal radiation therapy technique that allows us to deliver a high dose to the tumour and minimise dose to normal healthy cells.


Volumetric Modulated Arc Therapy (VMAT) is an advanced form of IMRT. Radiation is delivered as the treatment machine rotates, creating a precise sculpted dose to the target volume.


Stereotactic Body Radiation Therapy (SBRT) or Stereotactic Ablative Radiation Therapy (SABR) is a technique that delivers a high biological dose with great precision in a small number of treatments.


Deep Inspiration Breath Hold (DIBH) is a technique used for left-sided breast and other treatment sites. The patient takes a deep breath and holds while radiation is delivered.


Total Body Irradiation (TBI) is a form of radiation therapy used in the treatment of blood related cancers such as some types of leukaemia. TBI is often given in conjunction with chemotherapy as part of the preparation for a blood stem cell or bone marrow transplant.


Cranio-Spinal Irradiation (CSI) is a radiation technique used for patients with central nervous system malignancies, such as medulloblastoma and primitive neuro-ectodermal tumours.


A radiation treatment machine mounted on a robotic arm. The system tracks tumours and patient movement and adjust accordingly to ensure treatment is delivered with a high degree of accuracy.

High Dose Rate (HDR) Brachytherapy

HDR Brachytherapy treatment involves using a sealed radioactive source (or material) that can be placed inside a body cavity or tissue, or directly adjacent to it, to deliver a high dose of radiation to the cancer with a very low dose to surrounding tissues and organs. The radioactive material is attached to a wire and travels in a tube, needle or applicator to deliver the required dose and then retracts back into the treatment unit. Brachytherapy can be used alone or in conjunction with external beam radiation. You will not be radioactive at the end of the procedure.

Intraoperative Radiation Therapy (IORT)

IORT is a form of radiation therapy that is suitable for select women with early breast cancer. The treatment is delivered to the surgical cavity at the time of the surgery or at a later time at the tumour site.
