超音波による生体眼薄膜厚の計測—第3報 拍動部分の検出

Ultrasonic measurement of the thickness of living ocular walls. III. Recognition of pulsation site

　頭部固定台を寝台と分離することにより，比較的安定に眼球後極部からの超音波信号を採取することができた．これにより，強膜前面に拍動部分の存在することが示唆された．

We succeeded in detecting physiological pulsation of the posterior wall of the eyeglobe by means of trans-pupillary water-immersed echography. This was achieved by introducing a head-rest system separated from the bed which allowed to block conduction of body movements and vibrations to the probe of the echo-gram. The recorded pulsation was located at the level of anteior scleral surface in the posterior fundus.
