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:
Having configured the network targets appropriately (see below), one can enter various query keys and obtain from the PACS a list of studies for one or more patients, which will be displayed as a tree in the left panel.
One can then select either everything returned by the query (top node in the tree), or a single study or series to retrieve. Initially, one may leave the "Retrieve only dose series" box checked to reduce the volume of material retrieved.
The retrieved instances will be listed in the right panel, and can be explored by expanding the tree.
The following example shows a CT study that contains not only a dose screen save image, but also a radiation dose report.

If any GE or Siemens or Toshiba or Philips CT Dose screen save images are present, one can select the image and press the View button to show its contents. The GE dose screens are usually in Series 999; the Siemens dose screens are usually in Series 501; the Toshiba dose screens may be in Series 1000, or in any series (and hence can be hard to find), and may span multiple pages (multiple images); the Philips dose screens are usually in Series 1 and have a Series Description of "Dose Info", though sometimes the dose screen is absent and the dose information is present inside the localizer.

One can also press the Report button to perform OCR or process the "header" as required, and extract the information in a tabular form in a new popup window. The "Show only dose summary" checkbox can be turned off prior to pressing Report in order to show the per-series information, as in the following screenshot:

Reports about multiple studies can be generated at the same time if one selects higher in the tree in the right panel, as in the following screenshot:
 |
Note that when entire patients or studies are selected, and the studies contain both dose screens and RDSRs (whether generated by the modality, or this tool), then there will be multiple entries in the resulting report.
Detailed information about the acquisition parameters related to dose that is not included in the dose screen save or its header can be obtained if one unchecks the "Retrieve only dose series" box, then retrieves the entire set of CT images for the studies, and then generates the report again after unchecking the "Process only dose series" box ... this will be slower, of course, but results in more complete information, similar to what one might find in a Radiation Dose SR report. This may also help if the query is unable to find any dose screens using the series level information (e.g., if dose screens have been lumped into series with localizers, or the PACS database has coerced the series level description into something unexpected).
A textual rather than tabular form of report may be obtained by unchecking the "Show tabular layout in report" checkbox. The tabular form is implemented using HTML tables, and can be cut-and-pasted into other tools using mouse selection and the conventional key board shortcuts for the platform (e.g., ctrl-A, ctrl-C, ctrl-V for Windows to cut-and-paste everything).
Any SR instances present, including Radiation Dose SR instances, are also retrieved, even when the "Retrieve only dose series" box is checked, and will be listed in the right panel, and can be explored by expanding the tree.
