System for Testing Ultrasound Equipment

The system, marketed by Onda Corp. (Sunnyvale, CA, USA), a manufacturer of measurement instrumentation for medical ultrasound, provides precise six-axis positioning and data acquisition from an acoustic sensor in a water tank, for accurate measurement of acoustic fields. Introduced in 1992 by NTR (Seattle, WA, USA), the AIMS rapidly spread worldwide and has become the gold standard for measuring ultrasonic fields. This workhorse of an acoustics laboratory is now found at most major manufacturers of medical ultrasound equipment, as well as university laboratories and government-regulatory agencies.

The AIMS scanning system has recently been upgraded with dynamic new version 4.0 software, which makes the job of the U.S Food and Drug Administration (FDA)/International Electrotechnical Commission (IEC) compliance testing even simpler.

Dr. Arne Voie, director of research at Spencer Technologies (Seattle, WA, USA) stated, "We use the AIMS for production testing for our transcranial Doppler devices, which measure blood flow to the brain. Its auto-search for peak intensity allows us to easily measure acoustic parameters for government submissions, and it is a big help in the process of developing new devices.”

In addition to test and measurement products, Onda provides test and measurement services in beam characterization, sensitivity calibration, and power measurements. Onda Corp. also provides contract R&D services for customers seeking to design and build medical devices that use ultrasound.
