Major challenges in diabetic foot ulcer (DFU) treatment include compliance and routine clinical visits to facilitate healing. Virtual Medicine (VM) can greatly impact DFU wound care management with tools for remote patient monitoring (RPM). Herein, a novel low-cost smartphone-based imaging device was developed to provide physiological (in terms of tissue oxygenation) and visual measurements of DFUs. Quantitative changes in tissue oxygenation between the wound and peri-wound in DFUs are obtained using SPOT device in an IRB approved pilot study. On a long-term, SPOT has potential to offer a low-cost alternative for VM and RPM in DFU wound care management.
