UMS4 scanning tank

UMS4 is an advanced scanning system designed to provide users a comprehensive ultrasound measurements and characterisation platform for the purposes of research, development, and quality assurance.

If you have any specific questions about this product, please contact us.

UMS4 scanning tanks


Our redesigned system integrates a robust, highly accurate 3D positioning system with a Precision Acoustics developed control software package. This control software package manages the synchronisation requirements for scanning, data storage, and post-scan acoustic processing and computation.

Typical applications of UMS4

  • Beam profiling
  • Location of focal area
  • Pressure mapping
  • Measurement of acoustic parameters to satisfy the latest regulatory requirements needed for IEC62127-1, IEC61157, NEMA UD2 or FDA 510(k) submissions

System Supplied to University of Oxford

Ultrasound measurements rely on the ability to measure accurately the acoustic field. The UMS4 system has three motorised axes (x,y,z) each capable of a 6-micron repeatability.  The system supplied complete with an electronic control module and a PC with preloaded UMS software.  The software is optimised for interaction with Keysight Technologies DSO-X 3000 series oscilloscopes but the works with many other modern oscilloscopes.

Options include an additional “rotational axes positioning device” to facilitate accurate alignment of the transducer’s acoustic axis with the hydrophone; water conditioning system; hydrophone and transducer mounts.

To simplify purchasing for our clients we can also supply all power amplifiers and function generators.

More information about the UMS system and software is available on the UMS specification page.

3D scanning tanks FAQ's

The majority of acoustic measurements are made in water. However, whilst being cheap and readily available, tap water is not ideal for conducting acoustic measurements and should be conditioned before use in a test tank. For more information see our document on water treatment.

For measurements on diagnostic scanners we recommend an oscilloscope with sufficient bandwidth and high sampling rate.  The oscilloscope is an essential part of our system and we have designed our software around the Keysight Technologies (formerly Agilent) range of oscilloscopes. We usually supply an oscilloscope from the DSO-X 3000 series but we have configured the software for most oscilloscopes in this range.  There are also other scopes in the LeCroy and Tektronix ranges that are supported. Please contact us if you have an non-Keysight Technologies oscilloscope to confirm whether it is supported.  Even if it is not we may be able to write additional software to extend support to your device

Our software was originally designed to measure the acoustic parameters which relate to ultrasound safety. All measurements rely on the measurements being made with a calibrated hydrophone. If your application is not medical we can customise the software to display those parameters which are relevant to your work.
