Outline of Final Research Achievements

In this research, basic data of structure of sweat gland between paridrosis subject and healthy subject are compared and accumulated by use of the quantitative measurement method of amount of sweating of OCT analysis. In the experiment, the swept source OCT (SS-OCT) is used for imaging of sweat glands, where the longitudinal image resolutions 12 microns at the center wavelength of 1.325 microns. The en face OCT image of human fingertip is constructed and the eccrine sweat gland is selected by the region of interest (ROI) of the OCT image. We propose a method for extraction of the specific eccrine sweat gland by use of the connected component extraction process and the adaptive threshold method. From our experimental results, there is border size of an averaged radius of swept duct about 14 microns. It is noted that the structure and size of the sweat gland of paridrosis subject is larger than healthy subject.
