External Beam Radiation Therapy (EBRT) can be delivered using various techniques. Your treatment is carefully planned for your individual needs. Speak with your Radiation Oncologist for more information on which technique may be of most benefit for your treatment outcomes.

Here are some examples of radiotherapy techniques offered at the NSCC:

A Radiation Therapist using an IGRT technique before radiotherapy is delivered 


Image Guided Radiation Therapy (IGRT) is the routine process of using verification imaging before Radiation Therapy is delivered. These images might be X-ray (2D) or CT (3D) images, using equipment integrated into the Linear Accelerator. These images allow the Radiation Therapists to visualise the treatment area and to precisely adjust for daily variation in position. 



Intensity Modulated Radiation Therapy (IMRT) is an advanced radiotherapy technique that delivers high-precision radiotherapy using complex computer-controlled shielding called Multi-Leaf Collimators (MLCs).



Volumetric Modulated Arc Therapy (VMAT) is similar to IMRT however the radiation is delivered in a continuous rotation or 'arc', with the machine moving around the patient.



Stereotactic Body Radiation Therapy (SBRT) is a specialised technique that delivers a very high amount of radiation in a small number of fractions. It is most often suitable for small, well-defined lesions. The Radiation Oncologist will determine if SBRT is suitable for your treatment area.


Frameless cranial SRS/SRT

Stereotactic Radiosurgery/Radiotherapy (SRS/SRT) is a specialised technique that treats lesions in the brain with a very high radiation dose. This may be delivered in one or a few treatments. Patients will have a custom mask made to ensure positioning accuracy.


DIBH for breast radiotherapy

Deep Inspiration Breath Hold (DIBH) is a technique suitable for left-sided breast radiotherapy that can reduce radiation exposure to the heart and lungs. The planning CT scan will assess which technique (free-breathing or DIBH) is most suitable for the patients individual anatomy.


Prone breast radiotherapy

Breast radiotherapy can be delivered in the 'supine' or 'prone' position. Some patients may benefit from the 'prone' position, which means the patient is positioned laying on their stomach with the treated breast falling away from the body. The Radiation Oncologist will assess which position is most suitable for each patients anatomy at the time of clinical assessment.


Total Body Irradiation (TBI)

Total Body Irradiation (TBI) is a treatment method used for haematological cancers. It precisely delivers radiation to the entire body in preparation for blood stem cell or bone marrow transplants.


Some other techniques may be offered under our Clinical Trials.
