We aimed to perform non-invasive characterization of carotid plaque and estimation of the fat content of the liver with ultra The application of the sound wave velocity change method has been investigated. Experiments on biological phantoms under pseudo-beating conditions have resulted in the successful delineation of UVC images. When attempting to apply the method to living organrisms, the complex motion caused by the beating and the effect of camera shake during measurement resulted in a reasonable UVC imaging was found to be difficult to delineate. In this study, we tried to draw UVC images of the forearm, which is less affected by beating, so we report.
