Open-Source Tool Enables Vendor-Neutral CT Does Archiving

Researchers in Boston have developed an automated radiation-exposure monitoring system that extracts detailed CT exposure data from image repositories. Thanks to optical character recognition (OCR) software, the open-source software scheme can gather data from virtually any CT scanner model, even older ones without DICOM-based dose displays.

In a sample of 54,549 CT encounters over the past decade, the modified open-source toolkit achieved nearly 100% accuracy in data capture, according to a presentation at the recent RSNA 2011 meeting...
