Paper Abstract

The authors report on the Signa Tutor, a magnetic resonance imaging (MRI) simulator. Their goal was to cost-effectively teach MRI scanning techniques to technologists and physicians using the simulator, off-line from the General Electric (GE) Signa scanner. They implemented the scanner's user-interface for image acquisition, using HyperCard together with an Oracle database to maintain images and scan-parameters. The software operates on a standard Apple Macintosh-II computer. Two aspects of the project are reported in this paper. First, enhancements to the Signa Tutor, including Signa 4.0 pulse sequences and new images, are presented. Second, a time and motion study that compares image acquisition learning time using Signa Tutor verses traditional technologist training on the GE-Signa console is described. In this study, an expediency test was performed which compares the speed at which an operator performs a single scan sequence on both devices.
