About

Aya Kamaya is a leading researcher at the intersection of medical imaging and radiation oncology, with a primary focus on advancing ultrasound-guided interventions for cancer treatment. Her most notable contribution is the development of a robotic 4D ultrasound system for real-time intrafractional guidance during liver stereotactic ablative body radiotherapy (SABR). This groundbreaking work, detailed in her highly cited 2016 paper, addresses the critical challenge of tracking moving liver tumors during treatment. Kamaya’s system design cleverly incorporates beam avoidance strategies, ensuring that the robotic ultrasound probe does not interfere with the delivery of Volumetric Modulated Arc Therapy (VMAT). By estimating the proportion of liver SABR cases suitable for this approach, she has provided a practical roadmap for clinical deployment. Her research directly enhances treatment precision, potentially reducing toxicity to healthy tissue while improving tumor targeting. With 20 citations for this seminal work, Kamaya’s impact is growing as the field moves toward more adaptive, image-guided radiotherapy. Her innovative integration of robotics and real-time imaging positions her as a key figure in the evolution of non-invasive liver cancer therapy.
