WebSFDI is a novel, noninvasive, wide-field imaging technology capable of quantifying oxygenated and deoxygenated hemoglobin levels, as well as, total hemoglobin and tissue saturation. The authors investigated SFDI (before and after selective vascular occlusion) on pedicled fasciocutaneous flaps on Wistar rats. WebSFDI can rapidly generate wide-ﬁeld optical property maps using a camera and projector in a non-contact conﬁguration. These advantages have led to the exploration of SFDI for a number of clinical and research applications [1,4–6,8,9]. Despite its advantages, there are several practical challenges to translating SFDI to clinical settings.
