Description
Summary:This paper presents a novel high-performance computing (HPC) system for compute-intensive medical applications. Our system provides surgeons a framework for utilizing remote HPC resources with a secure execution environment by a public key cryptography and a high-speed data transmission by a real-time lossless data compression algorithm. Our implementation on a cluster of 64 off-the-shelf PCs with 128 processors has successfully demonstrated HPC benefits by reducing the turn-around time for the nonrigid registration of liver CT images of 512×512×159 voxels from about 17 h on a sequential system to about 12 min.
