David Clunie posted a tool called DoseUtility

DoseUtility is a free open source tool with a user interface to query, retrieve, import, and extract and report radiation dose information. It is written in pure Java, will run on any platform and can be started from the web without local installation. It can:

• Import files from a CD or the local hard drive or a shared network drive or any other media, with or without a DICOMDIR
• Query and selectively retrieve dose information or entire CT series from remote DICOM devices
• Extract the dose information from a GE or Siemens or Toshiba CT screen saved image using Optical Character Recognition (OCR)
• Extract the dose information from a Philips CT screen save or localizer image using the proprietary Standard Extended SOP Class Exposure Dose Sequence information in the "header"
• Generate Radiation Dose Structured Reports (RDSRs) from such extracted dose information
• View the contents of dose screen save images and RDSRs
• Tabulate the contents of dose screen save images and RDSRs for multiple patients and studies
• Validate the content and structure of RDSRs
• Submit de-identified RDSRs to Dose Registries (using the Submit Dose Information transaction of the IHE Radiation Exposure Monitoring (REM) profile
