Abstract
Several years ago we developed a high resolution ultrasonic B-scanner for general purpose diagnosis, but specifically oriented for use in ophthalmology.1 In the special case of ophthalmology, high resolution is necessary because of the small size of the eye and the amount of detail required for the diagnosis. High axial resolution (.3mm) was achieved through the use of wideband transducers operating at a nominal frequency of 10MHz. Adequate lateral resolution (approximately 1mm) resulted through the use of focused ultrasonic beams.
