The pulse-echo test is used to evaluate the performance of ultrasonic probes before manufacturing ultrasonic systems. However, commercial alignment instruments are very large and use complex programs with long operation times.
To develop a low-cost alignment instrument used in the pulse-echo test for evaluating the performance of various 2D and 3D ultrasonic probes.
The developed alignment instrument can be aligned with the X, Y, Z, azimuth, elevation, and tilt axes with manual structure to support mounting fixtures that hold 2D and 3D ultrasonic probes. Each axis has a manual lever and is designed to have no movement when fixed. In particular, tilt and azimuth directions are designed to move more than 5∘ left and right.
The probe mounted in the X, Y, and Z axes can move at above 50 mm. The probe mounted in the azimuth, elevation, and tilt axes can move more than 5∘ in the left and right directions. The pulse-echo test using commercial ultrasonic probes showed maximum error rate of less than 5%.
Our developed alignment instrument can reduce costs by eliminating the need for shortening inspection times for probe manufacturers.
脉冲回波测试用于评估超声系统制造前的超声探头性能。然而，商用对准仪器非常庞大，使用复杂的程序且操作时间长。
开发一种低成本的脉冲回波测试用对准仪器，用于评估各种 2D 和 3D 超声探头的性能。
所开发的对准仪器可以手动对准 X、Y、Z、方位、仰角和倾斜轴，以支持安装固定 2D 和 3D 超声探头的夹具。每个轴都有一个手动杆，设计为固定时无移动。特别是倾斜和方位方向的设计可以左右移动超过 5°。
安装在 X、Y 和 Z 轴上的探头可以移动超过 50 毫米。安装在方位、仰角和倾斜轴上的探头可以在左右方向移动超过 5°。使用商用超声探头进行的脉冲回波测试的最大误差率小于 5%。
我们开发的对准仪器可以通过消除缩短探头制造商检查时间的需要来降低成本。
