Research Abstract

In the present study, I have developed the image diagnosis system that can instantly and objectively specify the name of allergic skin disease that appears in various symptoms. The proposed system can reproduce the blood flow distribution and color of wide skin surface by using laser in combination with white light. The data of the blood flow and skin color of various patients are accumulated to the database and are utilized for skin disease diagnosis.
