Abstract
Recently, ultrasound transducers in several tens MHz band, which can give the spatial resolution higher than several tens micrometers, have been intensively studying for applying to medical diagnostic fields of ophthalmology and dermatology. In this paper, the background of the studies, structures and characteristics of the transducers, and images obtained by the transducers are briefly reviewed.
