Latest Patents

Hiroshi Koga holds 3 patents that showcase his expertise in skin disease diagnostics. His latest patents include a method for analyzing longitudinal pigmented bands on the nail plate or skin color hues for diagnosing skin diseases. This method involves a diagnostic device and a computer program that enables the determination of whether a longitudinal melanonychia is caused by malignant melanoma or a benign nevus. The process corrects color variation in dermoscopic images through standardization of color balance, independent of the imaging device or operator.

Another significant patent focuses on the method of discriminating longitudinal melanonychia and visualizing its malignancy. In this method, RGB parameter values of each pixel in a digital color image are treated as three-dimensional vectors. By obtaining latitudinal and longitudinal variables for each vector, Koga defines a distribution of points to find a discrimination index. This index is classified according to a threshold to determine whether the condition is malignant or benign, allowing for effective visualization of the malignancy.

Career Highlights

Koga has worked with prestigious institutions such as Shinshu University and Waseda University. His work has been pivotal in bridging the gap between technology and medical diagnostics, enhancing the accuracy of skin disease assessments.
