An open architecture for medical imaging systems

Integration of medical imaging is the goal of many standards. Interfile and Digital Imaging and Communications in Medicine (DICOM) standards have made great strides in this area. The impact of DICOM is greater owing to its wider acceptance. However, the lack of conformance testing makes interoperability difficult, often requiring expensive consulting teams in a mixed-vendor environment. DICOM is difficult to learn and deploy because it does not use modern software paradigms. Many hardware and software advances in computer architectures and communications could greatly enhance diagnostic imaging if they could be quickly incorporated into medical imaging standards. These problems led to consideration of a solution able to take advantage of state-of-the-art technology and to allow diverse implementations while ensuring the accurate interchange of information between health care providers. It is an object-oriented system information model, with the common object request broker architecture (CORBA) as the vehicle to ensure interoperability between different implementations of the model. This report presents the model.
