Fujitsu Develops Digital Annealer to Optimize Radiation Treatment Plans

Fujitsu Laboratories, Ltd. with researchers at the University of Toronto (U of T) announced the development of a technology to optimize radiation treatment plans for Gamma Knife radiosurgery, leveraging Fujitsu’s quantum-inspired computing technology, the Digital Annealer.

Gamma Knife therapy is a noninvasive stereotactic radiation device that delivers gamma rays to the affected area. It is used mainly to treat the head, including brain tumors and cerebrovascular malformations.

Gamma Knife radiation therapies are used to treat different diseases including brain tumors and arteriovenous malformations. The process of creating treatment plans using conventional methods is often complex and time-consuming, and doctors must spend time making painstaking and detailed adjustments to determine how much radiation should be administered to a target while minimizing dose to surrounding tissue. However, with the newly developed technology, medical professionals can create treatment plans within one minute, maintaining the same level of accuracy as conventional methods, while calculating a huge number of possible combination patterns of where and how much dose to deliver with the Digital Annealer. So, this technology frees doctors to devote more time and energy to ensuring patients receive the most effective care possible.

Going forward, Fujitsu Laboratories and U of T researchers will continue to test the effectiveness of this technology based on data from more patients and will continue to develop technologies that offer the potential to contribute to medical science and society at large. Future potential projects include shortening the time required for Gamma Knife treatment processes themselves rather than the treatment plans or applying this technology to other radiotherapy methods.
