CT Dose Retriever

Build a database of CT doses from a Fuji Synapse PACS

DoseRetriever is a program that retrieves CT dose screens from the Fuji Synapse PACS, converts the screens to text (using CT Dose OCR), and populates a SQLite dose database for data mining.

This program performs bulk automated retrieval of CT dose screens from a Fuji Synapse PACS, matching user specified parameters such as date range and procedure codes. The system incorporates CT Dose OCR to process the retrieved dose screens, and can accurately parse the resulting text data such as Dose Length Product. Data is written to a local SQLite database for further data mining and analysis.

The system runs entirely portably, with no backend reconfiguration of the PACS system required. This project depends on executables from the DCMTK project for DICOM file processing.
