GSRFViewer Overview

GSRFViewer, Columbia Department of Medical Informatics, Jan-Mar, 1999

A Java application for automatically creating graphical presentations of coded radiology data.
How it is used
  • GSRFViewer will be the graphical system for CISIS - Columbia's Integrated Speech Interpretation System.
My role
  • As a visiting researcher at Columbia, designed, implemented, and published a graphical schema for presenting coded radiology data (GSRF)
  • Also designed a meta-syntax (GRAL) for automating the creation domain-specific GSRFs.
  • Implemented both GSRF and GRAL as a Java application.

Applicability to Medical Informatics
Abstract An increasing amount of radiological information is available in coded form. In its raw form, such coded data is not well suited to review by humans. There is a need for methods to convert this coded data into a form that is easily understandable by humans. One solution is to create graphical presentations or "drawings" of the data. To do this, a generalized graphical presentation system, consisting of three main components, was developed. The Graphical Schema for Radiology Findings (GSRF) provides a generic model for the description of graphical presentation features. The Graphical Radiology Abstraction Language (GRAL) is an XML-based markup language that provide a syntax for specifying graphical presentation templates, data attributes, and the mappings between attributes and graphical presentation features. The GSRFViewer is a Java application that implements the GSRF and GRAL.
