Annular Array Probe for Ocular Tissues Imaging

The ocular region was examined by echography using a high resolution annular array probe. The following results were obtained: (1) Homogeneous and clear images of the ocular region with excellent axial resolutionand lateral resolution. (2) The occurrence of artifacts, which are specific to ultrasonograms, was relatively low, and images showing the precise shape of the eyeball without distortion were obtained. (3) Since the distance between the transducer and eye surface was relatively long, adequate images of the anterior ocular region were obtained, as with the sector scanning procedure by the immersion method. (4) As a result of long focal zone, each site of the eyeball could be distinctly and homogeneously visualized.
