Abstract:
New clinical research suggests that change in the retinal blood vessel caliber is an important indicator for earlier diagnosis of cardiovascular diseases. One approach to quantify the severity of the caliber change is the arteriolar-to-venular diameter ratio (AVR). To facilitate a large-scale clinical study, it is essential to have an accurate and efficient system to compute the AVR. In this talk, I will present a new method to obtain AVR. The core of the technique is a new vessel edge tracking method which combines the method of finding pattern of vessel start point and pixel grouping technique. An edge profile checking method is developed for filtering noise and other objects, and tracking the real vessel edges. From the filtered edges a rule based technique is adopted for grouping the edges of individual vessels. From the vessel edges, the caliber is measured for each of the cross-sections in a vessel-segment. Currently, we are in the process of developing software based on the method. The system has interested clinical research groups worldwide and will be tested in clinical studies.
