Precision Radiation Oncology
Precision radiation oncology is a cutting-edge approach to cancer treatment that tailors radiation therapy to the unique characteristics of each patient’s tumour. By integrating advanced imaging, molecular biology, data analytics and artificial intelligence (AI), this approach ensures that radiation is delivered with remarkable precision, targeting tumour cells while minimizing damage to healthy tissues.
AiMS researchers are using the Ethos technology platform, which combines anatomical imaging, radiation delivery and AI to achieve unprecedented accuracy in treating complex tumour sites. Researchers and clinicians are employing 3D radiation dosimeters to better understand how radiation doses are delivered to multiple small, non-coplanar lesions—areas that are difficult to target with conventional delivery methods. Additionally, the impact of organ deformation due to breathing or anatomical changes is being investigated and incorporated into the treatment planning process.
Ultimately, our work in precision oncology will enable the next generation of radiation therapy, marked by superior accuracy and individualized treatment. This approach moves away from population-based, one-size-fits-all prescription and towards a more personalized, patient-centered model of care.
Mapping radiation dose. Utilizing polymer gel dosimeters (left image) allows researchers to spatially measure radiation doses delivered by linear accelerators used in cancer treatment. Researchers are then able to compare delivered and planned radiation doses in specific regions (middle image) and in full space (right image).
