What is Radsearch?

Radsearch is a web application for searching large databases of radiology reports. It was designed to help our radiologists access reports in order to:

• Identify cases for decision support and comparison at the point of care


• Find cases on a specific indication or feature for lecture


• Improve education materials


• Perform inclusion criteria-based searches to identify cases for IRB-approved research

How does it work? What technology are you using?

Radsearch is built using the ruby programming language and the rails web programming framework. It uses a MySql database and an indexing system called Sphinx to produce sub-second response to searches. We use UltraSphinx to integrate the rails application and the sphinx indexing system.

Developer Notes

The database schema and associated sphinx indexes are just an example and can be adjusted to fit institution or user needs.
