RAQuantify is an innovative attempt to apply state-of-the-art computer vision algorithms to the automatic quantification of rheumatoid arthritis (e.g. automatic joint space measurement). It is aimed at two main fields:

• Clinical research on rheumathoid arthritis and multi center studies

• Rheumatoid arthritis therapy monitoring

RAquantify is embedded in a Web service, and therefore allows shared use by several users in different geographic locations. It is under active development and processes DICOM data with minimal user input, with a current technical success rate of 93%.

If you are interested in more detailed information, please refer to Peloschek P, Langs G et al. (An Automatic Model-based System for Joint Space Measurements on Hand Radiographs: Initial Experience. Radiology. 2007)

In contrast to semi-automated approaches RAquantify performs the analysis fully autonomous. This has several advantages:

• It allows for the batch processing of large amounts of DICOM files

• It decreases the chance of reader variability, which is particularly relevant during multi center studies

RAquantify is developed as a part of the AAMIR project, at the Universities of Technology Graz and Vienna, and the Vienna Medical University.

In March we will participate on this years' ECR 08 imagine exhibit.
