The Southern Arizona Limb Salvage Alliance (SALSA) at the University of Arizona College of Medicine took the top abstract poster award for Case Series/Study at the Symposium for the Advancement of Wound Care (SAWC) held at the San Diego Convention Center this past week. The cutting-edge work, which involves a new optics technology called Spatial Frequency Domain Imaging (SFDI), allows clinicians to quantitatively image and assess foot circulation in patients at high risk for ulcers. “This technology gives additional insight into tissue vascular health so clinicians can improve the lives of patients”, noted Amaan Mazhar, PhD, VP of Research and Development at Irvine startup Modulated Imaging. “We are honored to work with the multidisciplinary surgeons and scientists at UA’s SALSA. Their work has been at forefront of discovery in lower limb care and together we will take this work to the next level ”
David G. Armstrong, Professor of Surgery and co-Founder and Director of SALSA was equally enthusiastic, “To be able to see what some call the ‘oxygen anatomy’ of a given body part in real time and with high definition is potentially game-changing. It’s like being given an additional sense.” Armstrong and his coworkers believe that technologies like this will soon allow physicians and surgeons to be able to make clinical decisions that could save legs and prolong life for people at risk for amputation.
Celebrating its 30th year, SAWC hosts more than 3000 delegates and others each spring. Mazhur and Armstrong co-authored the study with UA vascular surgery resident Craig Weinkauf, Kairavi Vaishnav of SALSA and David J. Cuccia of Modulated imaging. The study was funded by the National Institutes of Health.
