富士通：伽马刀进行放射治疗：数字退火炉的放射剂量计算
富士通实验室：
多伦多大学：
我们共同高速解决了“应用量子计算技术的组合优化问题”。
量子计算：
通过使用“数字退火炉”技术，我们开发了一种可在短时间内为伽玛刀（注3）生成放射治疗计划的技术。
伽玛刀治疗：
伽玛刀治疗可治疗脑部疾病，例如脑部肿瘤和动静脉畸形。
少量的伽玛射线从头部的各个方向施加到脑肿瘤的患处。
用“数字退火炉”计算：
这次开发的技术使用“数字退火炉”来计算“照射位置和照射剂量的巨大组合模式”。
传统上，医生必须根据自己的经验手动花费几个小时。
此治疗计划的生成将在几分钟内以相同的精度完成。
这样可以减少医生在治疗计划上花费的时间。

Fujitsu and University of Toronto Researchers Develop Quantum-Inspired Technology to Optimize Radiation Treatment Plans for Brain Tumors and Other Diseases
Fujitsu Laboratories, Ltd.
in collaboration with researchers at the University of Toronto (U of T )today announced the development of a technology for dramatically streamlining the creation of radiation treat the Digital Annealer, which rapidly solves combinatorial optimization problems.
Gamma Knife radiation therapies
are used to treat illnesses including brain tumors and arteriovenous malformations.
The process of creating treatment plans using conventional methods
is often laborious 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.
With the newly developed technology, however, medical professionals
can create treatment plans in roughly one minute, maintaining the same level of accuracy as conventional methods,
while simultaneously calculating a huge number of possible combination patterns of where and how much dose to deliver with the Digital Annealer.
