Dicoogle is a medical image repository allowing indexing and retrieval of images over multiple, distributed PACS servers. It supports query and retrieval by means of free text and metadata-based querying. Free text queries support Boolean operators to refine the query. Additionally, there are several other functionalities available, such as nearby terms and flexible range search. It has a GUI-based administration panel for configuration and service supervision.
The paradigm introduced with the Dicoogle index engine allows execution of queries over a set of distributed DICOM repositories, which are logically indexed as a single federated unit. This runs queries against all Dicoogle nodes as though they were a single index. Users can enter search criteria once and access several search engines simultaneously in real time.
