More Applications and Research Interests

We are constantly evolving and focusing on innovation. We believe that in the rapidly changing world of medicine, radiotherapy and in particular particle therapy, innovation must be at the forefront of our thinking. At Advanced Oncotherapy, we continue to look for change and continue to look for what we believe will be the future game changers.

Improved targeting with proton imaging

The high sensitivity of proton beams to tissue changes makes adapation more important than in conventional radiotherapy. This requires imaging information relating to the interaction of the beam with the patient's tissue. The conventional approach of X-ray imaging resuts in uncertainties which can be reduced when using proton beam imaging. The patient is imagined with a higher energy beam than used for treatement and the stopping powers deduced from the image are scaled to the correct treatment energy. This allows for a significant reduction in uncertainties in the dose deposition of the headron beam. As part of the PRaVDA Consortium, we are committed to support the development of new concepts and instrumentation to provide accurate information about the proton beam's dose, energy and profile before and during treatment. Please see our collaboration on the PRaVDA project as an illustration

Use of heavier ions, including Helium

Although proton therapy is already demonstrating its potential advantages over X-ray radiotherapy, the complete advantages are not yet fully exploited by current proton therapy systems. Circa 150,000 patients have been treated with proton therapy, which is the most common type of light ion therapy and has been practiced the longest. The use of heavier particles such as Helium and Carbon ions is slowly gaining traction. This interest is based on the greater confirmity and destructive power of those particles, and their greater radiobiological effectiveness.

Greater potential hypo-fractionation

Possibly the most important future frontier for charged particle therapy is hypofractionation. It has the real potential to improve patient outcomes and life quality. Today, hypofractionation is not able to be fully realised with legacy proton therapy systems. In parallel, proton therapy should continue to improve conformity through scanned microbeams and physical collimation. Scanned beams are preferable. Improvements in patient modelling, dose calculation accuracy and target motion solutions will also serve to build confidence for increased hypofractionation using protons.
