Auckland is at Alert Level 3 until at least 6 October 2021.
During this time, ARO continues to provide services to those requiring radiation therapy.
You will be contacted directly with any changes to your appointments.
New patient referrals will be accepted but please note there may be some delays to starting treatments due to the current COVID-19 conditions. Please be aware of border requirements (here) if you need to travel across alert level boundaries for appointments.

3DCRT, Electron and IMRT

Three Dimensional Conformal Radiation Therapy (3DCRT)

3DCRT is the most traditional form of treatment. Depending on the diagnosis it can be the preferred treatment and is highly effective. ARO has a variety of equipment to help patients feel comfortable whilst ensuring their position is maintained and reproduced for each treatment.

Electron Treatment

Linear accelerators produce two types of radiation, photons and electrons. Electrons cannot travel as far into the body as photons so are not as commonly used but are very good for treating superficial or shallow targets. A simulation (pre-treatment planning) appointment is required to determine the best treatment position but a CT planning scan is not usually required for electron treatments . 

Intensity Modulated Radiation Therapy (IMRT)

Similar to other techniques IMRT shapes the radiation beams closely around the target.  The key difference with IMRT is the intensity of the radiation beam can be adjusted in multiple small volumes. This means higher radiation doses can be focused to regions within the target.  Due to the complexity of the software/system, IMRT requires additional planning time and safety checks.  It also requires longer daily treatment times.

IMRT has largely been replaced by VMAT at ARO due to the speed of delivery but remains a technique ARO are technically able to deliver should it be the best option for a patient.
