本文提出了一个集群系统，适用于高分辨率的图像处理在互联网上手术过程中的框架。该系统实现了高性能计算（HPC）辅助手术;这允许外科医生在手术室远程使用HPC资源。该系统的一个可用应用是全髋关节置换（THR）手术中活动度（ROM）调整的术中估计器。为了在手术期间执行这种计算密集型估计，我们在64台PC的集群上并行化ROM估计器;每个PC有两个CPU。加速技术，如动态负载平衡和数据压缩方法被纳入系统。该系统还通过因特网提供具有安全执行环境的远程访问服务。我们将该系统应用于在大坂大学医院进行的实际THR手术，并确认其实现了术中ROM估计，而不会降低图像分辨率并限制估计区域。
This paper presents a framework for a cluster system that is suited for high-resolution image processing over the Internet during surgery. The system realizes high-performance computing (HPC) assisted surgery; which allows surgeons to utilize HPC resources remote from the operating room. One application available in the system is an intraoperative estimator for the range of motion (ROM) adjustment in total hip replacement (THR) surgery. In order to perform this computation-intensive estimation during surgery, we parallelize the ROM estimator on a cluster of 64 PCs; each with two CPUs. Acceleration techniques such as dynamic load balancing and data compression methods are incorporated into the system. The system also provides a remote-access service over the Internet with a secure execution environment. We applied the system to an actual THR surgery performed at Osaka University Hospital and confirmed that it realizes intraoperative ROM estimation without degrading the resolution of images and limiting the area for estimations.
