Developing the next generation of ultrasound that industry can rely on

We provide services for ultrasound field measurement and test instrument calibration, as well as consultancy, advice and training. Our in-house modelling and measurement expertise enables us to design, build and validate bespoke instruments using ultrasound-based technologies. Purpose-built facilities and unique capabilities allow us to solve the most complex of measurement problems. We provide consultancy to assist with design, prototyping, production and optimisation, as well as quality assurance issues. Our UKAS-accredited hydrophone calibration services provide equipment manufacturers with the traceability required for regulatory approval.

NPL supports the development of new ultrasound imaging techniques to enable earlier diagnosis and treatment. Our in-depth understanding of the underlying physics, combined with traceable measurement capabilities, makes us the ideal partner for the development of new technologies and to support the demonstration of compliance to international regulatory standards for medical devices, such as EU MDR 2017/745.
