Development of coagulate map formation algorithms to carry out treatment by laser coagulation

The eye's fundus is a complex object with a high density of filling vessels. The procedure of fundus treatment requires a lot of experience and skill from the physician. The basic tool in fundus treatment is laser coagulation, when a series of metered microscopic thermal wounds - laser coagulates - are applied in edema on the eye's retina. Currently available software packages are focused first on the use of the specified template (pattern) for coagulate location. Effects of the pattern application are caused by irregular coagulate location by reason of high variability in edema and vasculature forms. The paper presents algorithms for calculating a coagulate map within the framework of the solution of the sphere close-packing problem in a random region and research results for developed algorithms. For automatic coagulate arrangement, we proposed a software package including the proposed algorithms.
