Advanced Online Adaptive Radiotherapy for Precise Cancer Treatment

Your body changes throughout cancer treatment — and so can the tumour’s position. With Ethos Hypersight Radiotherapy, daily changes are tracked so your doctor can quickly adjust the treatment area, keeping the radiation focused on the tumour while protecting surrounding healthy tissue.
Ethos Hypersight Radiotherapy is a radiation adaptive therapy that uses advanced imaging and smart technology to re-optimise your treatment every single day, helping your doctors deliver the right dose exactly where it’s needed.
Traditional radiotherapy uses the same treatment plan from start to finish, while Ethos Therapy refines your plan daily for better accuracy and personalised care.
Ethos is suitable for many types of cancers, especially in areas that move or change shape during treatment, such as:
It is particularly useful for complex or advanced-stage cancers, where daily anatomical changes can impact treatment accuracy.
Importantly, this list is not limited. Ethos can also be beneficial for other treatment sites, especially when the tumour shrinks or changes shape throughout the treatment journey, allowing the radiation plan to be adapted for better precision and safety.
Your doctor will advise if Ethos is the right choice for your condition.
Although your treatment process may vary, the following should give you a general idea of what to expect:
Imaging is important in order to visualize the tumor, the surrounding organs, and your anatomy. High-quality, detailed images help us determine the exact size, shape, and location of the tumor in your body and accurately target it. The information gleaned from the images helps us determine the appropriate dose of radiation and how to deliver it most effectively.
Each treatment plan is personalized to your specific needs and specifies the amount of radiation the cancer cells should receive and from which angles. A schedule for treatment will also be developed during this phase.
When it’s time for treatment, your radiation therapist (RT) will help position you on the treatment table and make sure you’re comfortable. Just prior to treatment, images will be taken to allow your care team to verify the tumor’s exact size and location. Your treatment will begin once any relevant adjustments are made to your treatment plan.
The radiation is delivered by a machine called a linear accelerator (linac), which rotates around you as it projects the beam. With Ethos™ therapy, the rotating beam gantry is enclosed within the opening (the bore) so you won’t see anything rotating around you.
You will be in constant contact with your therapist through the integrated camera system and two-way intercom. Although the first treatment can take a bit longer due to additional setup, the entire process should take only a few minutes.
After your treatment, you’ll see your doctor for follow-up care. During this time, he or she will monitor your progress. Take this opportunity to ask your doctor any questions about your treatments, the status of your health, and any side effects you may be experiencing.
