Abstract

This report describes the three-dimensional (3D) visualization of skin andan eye using high-frequency ultrasound. A high-frequency ultrasound image has high resolution of the order of 10 mum and demonstrates the detailed internal structure of an organ. Therefore it is suitable for visualizing the structure of organs such as skin and the eye. The method of 3D visualization of skin and an eye we used is as follows. Initially, a high-frequency ultrasound image was obtained by using a transducer made of lead zirconate titanate (PZT) ceramics with a central frequency of 32 MHz. The spatial resolution of the image is 25 mum. Next, we applied a binarization procedure to the image and reconstructed a 3D image using a volume-rendering technique. From the results, we were able to separately image each layer of the skin and recognize the stratum corneum, epidermis and dermis. Moreover, we obtained images of the structure of the eve, that is, cornea and iris.
