NPL’s world-leading expertise in thermal imaging measurement has led to a breakthrough medical imaging device, called DFIRST, which generates temperature maps, thermography, of patients’ feet, to provide early alerts of potential problems. Such early detection would give more than a week’s extra time to take preventative action, reducing or even eliminating the ulceration and associated risk of infection.
The research is the outcome of a £1.2 million project funded by the National Institute for Health Research (NIHR) Invention for Innovation (i4i) programme. Since the project’s inception we’ve gone on to conduct clinical trials. Development is ongoing to ensure that the device has been tested against rigorous standards, ensuring it is as trustworthy as possible.
NPL conceived the idea of designing an artefact to provide a reliable reference, against which MRS thermometry measurements could be validated.
NPL have provided artefacts, and training, such that proof-of-concept studies could be performed. The concept has now been proven, and these artefacts now provide temperature traceability to the International Temperature Scale of 1990. They are world-first and have the power to make diagnostic conclusions from this technique a reliable and repeatable process.
