Our instrumentation research is focused around using ultrasound to perform industrial and medical measurements.
With backgrounds in high-speed field programmable gate array (FPGA) design, digital signal programming (DSP), digital communications and commercial electronics design we are able to utilise a wide range of techniques to solve problems throughout medical and industrial sectors
The Ultrasound Array Research Platform is a bespoke hardware system developed by our group at the University of Leeds to facilitate research into novel ultrasonic techniques that require the use of multi-element array transducers.
The UARP is a 96 channel system capable of independently transmitting and receiving, in parallel, from multiple elements of the array transducer.
The development of the UARP has focused on designing a flexible platform that aids research. As a consequence, we are able to prototype new techniques that require individual element control and capture of pre-beamformed, raw RF data.
