Introduction: Non-invasive methods for imaging varicose veins allow quantification and evaluation of venous diseases. This paper will describe a technique to visualize superficial (subdermal) varicose veins using digital infrared imaging and analysis with special software. Method: After image acquisition, the pictures were analysed with special software that segmented the varicose veins and calculated the surface area (per gridblock) occupied by varicose veins. By comparing the surfaces occupied by varices before and after a specific treatment, one can establish which treatment method performs the best. Aim for the future: Validation of this technique and quantification of the effects of treatment modalities for superficial (subdermal) varicose veins. We also investigate the use of this technique for the other clinical CEAP stages and the potential resemblance with duplex scanning.

It has been established that varicose veins are better visualized with infrared photography. As near-infrared films are nowadays hard to get and to develop in the digital world, we investigated the use of digital photography of varicose veins. Topics that are discussed are illumination setup, photography and digital image enhancement and analysis.
