Retinal Analysis
Automatic detection of lesions in retinal images
Download the flyerADCIS is developing advanced diagnostic tools in partnership with two prestigious institutes, the Center of Morphology Mathematics from the School of Mines in Paris, and the Lariboisiere Hospital in Paris. The project is funded by the French Government and the Ministry of Research. (Development started late 2001, and the final report was delivered in April 2003).
The goal of the project is to develop a fully automatic software product to process color images of the fundus of the eye provided by an angiograph. This set of algorithms is used by ophthalmologists and hospitals to study macula degeneration, and evolution of the diabetic retinopathy.

Starting from a color image of the retina, the software is able to perform the following tasks without any human interaction:

In addition to the Image Processing / Analysis tools available in the software, other features provided in the standard package include:
- Computation of measurements such as microaneurysm count, blood vessel thickness, number of branching points, densitometry data, etc.
- Simple database management to store images, results and patient information
- Image alignment to align images of the same patient acquired few months apart
- Manual interaction by the technician in charge of the analysis to validate results
All the development work is completed, and the software is currently in use by the medical staff of the Ophthalmology Group of the Lariboisiere Hospital. Several European organizations are seeking to bring this diagnostic capability to market.
In addition to medical diagnosis, this technique has application in retinal biometry.
The following screen capture shows the Graphical User Interface of the current version of the software product, and the results of the detection.
