JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Researchers from Aston University have developed a method to improve the accuracy of blood flow measurements in the feet of patients with Type 2 diabetes. The laser-based technique improves accuracy in detecting minute changes in microcirculation, and it improves on the method of laser Doppler flowmetry (LDF), which is commonly used to check circulation in the feet. LDF gives measurements in the form of blood flow averages — which doesn’t always give the doctor enough information. Changes at the microcirculatory level — involving the smallest blood vessels within...Read full articleRelated content from Photonics MediaArticlesTRUMPF, RSP Systems Partner on Wrist-Worn Glucose SensorA collaboration between TRUMPF Photonic Components and Danish company RSP Systems aims to enable wrist-worn glucose monitoring.
