A new A-mode biometry system for determining axial length measurements of the eye has been developed that incorporates a soft-membrane transducer. The soft transducer decreases the risk of indenting the cornea with the probe resulting in inaccurate measurements. A microprocessor evaluates echo patterns and determines whether or not axial alignment has been obtained, eliminating possible user error. The new A-scan requires minimal user skill and can be used successfully by both physician and technician.
一种用于确定眼睛轴长测量值的新型 A 型生物测量系统已被开发出来，该系统采用了软膜换能器。这种软换能器降低了探头压痕角膜从而导致测量不准确的风险。微处理器评估回波模式并确定是否已获得轴向对齐，消除了可能的用户误差。这种新型 A 扫描对用户技能要求极低，医生和技术人员都能成功使用。
