Abstract
This paper presents the initial steps taken to integrate the University of California at San Francisco Radiology Department's magnetic resonance (MR) scanners with its high-performance computing (HPC) grid. The objective is to improve patient care by enabling near real-time, computationally intensive medical image processing, directly at an MR scanner. A graphical software tool is described that was developed to run on the MR scanners for submitting processing jobs to the Departmental grid. The computationally intensive parallel reconstruction and quantification of large, multi-dimensional MR spectroscopic imaging (MRSI) data sets was used as the prototype application for this system. Initial results indicate that real-time processing of medical imaging data on a shared HPC resource is reliable and possible in a clinically acceptable time of less than 5 min. The Department's HPC resource is comprised of hardware owned by multiple research groups at three separate University facilities throughout San Francisco.
