Developing an application to support Non-Destructive Testing (NDT)? Need to create a DICONDE or DICOS solution? Looking for rock-solid software design, API and SDK support for a veterinary, dental, mammography or clinical research application? The DCF has you covered, with support for a wide variety of specialized domains including NDT, DICONDE, DICOS, veterinary, dental, digital mammography and clinical research customizations that require DICOM. Contact us to learn more and discuss your needs in detail.
The DICOM Connectivity Framework, or DCF, is a software product that enables a medical imaging system, including printer, scanner, modality, archive device, or workstation, to communicate with other devices over a network, using the DICOM version 3 protocol.
Supported languages & latest releases
- C# – Version 3.4.24c, released Mar. 19, 2019

Count on language, platform and domain flexibility
The DCF is the only DICOM solution that provides software developers a consistent API to C++, Java and C# .Net, as well as support for 32 and 64 bit Windows and Linux platforms. With DCF, you also get support for a number of specialized domains including DICONDE, DICOS, and veterinary customizations that require DICOM.
The DCF is a modular system, made up of various software components. These software components are combined with the OEM’s software on a particular computer platform to form a system. DCF components are tested by Laurel Bridge on a wide variety of systems covering just about any potential OEM system configuration.
Example: Dicom Server App
This is an example framework diagram for a DCF-based DICOM server application. Typically, a DICOM software application such as this requires significant implementation time and effort. With the DCF, a working application like this can quickly be crafted using a variety of base-classes and component libraries.
This diagram illustrates the layered approach to DCF design. The top application layer contains the
dcf_store_scp application component, which is the application entry point that managed initialization of the Common Services Adapters and other objects in the DCS and DSS libraries that perform the real work of implementing the Storage SCP.
The libraries in the application support layer perform the real DICOM work. The DCS library provides the basic classes for DICOM attributes or elements, data sets, PDUs, DIMSE messages, as well as higher level classes such as
DicomAssociation, for easily managing multiple concurrent associations,
DicomDataDictionary, numerous classes for network and file I/O and Data set/Image filtering. The DSS library provides the
StoreSCP class which registers as the handler for all Storage presentation contexts. C-Store-Request messages are dispatched to StoreSCP.
The common services interface layer provides abstract interfaces for services such as logging, application configuration, process control, and data storage/retrieval. StoreSCP invokes the
storeObject method on the DDS (DICOM Data Service) interface to locally store the dataset contained in the C-Store-Request message.
The common services adapter layer provides concrete implementations of common services. The LOG adapter (
LOG_a) library writes log messages to either the file system or the LOG Server, via the DLOG (Distributed LOG) CORBA interface. The Configuration Data Service adapter (
CDS_a) accesses configuration data from either the file system or the DCDS_Server, using the DCDS (Distributed CDS) CORBA interface.
The DICOM Data Service adapter might store image or SOP instance data to the file system, and may store header data in an SQL database system. An OEM that wishes to customize the behavior of the
store_scp for example to use a locally defined schema needs only implement one method:
storeObject. The developer can opt to hide all handling of concurrent network associations, DIMSE messages, and other complex DICOM details.
