Radiation Dose Intelligent Analytics for CT Examinations


RADIANCE is an open-source software pipeline designed to automatically extract and archive CT dose-related parameters from the dose sheets produced by CT scanners. It was designed at the Hospital of the University of Pennsylvania in Philadelphia, PA by a team of radiologists interested in dose monitoring and quality assurance. The power of RADIANCE is its ability to extract information from dose sheets produced by legacy CT scanners that cannot generate DICOM Dose SR structured reports. An overview of RADIANCE can be found in the November 2010 issue of the Journal of the American College of Radiology.

What does RADIANCE provide?

  • Small footprint; a set of scripts that can run on a Windows machine
  • Support for four major CT vendors: Siemens, GE, Toshiba and Philips
  • Automated extraction of parameters from CT dose sheets and storage in a relational database
  • Customizable pipeline for scheduled processing of CT dose sheets
  • Dashboard analytics
  • Ability to parse as well as generate RDSRs (radiation dose structured reports)
