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. WebSFDI is a non-contact, optical imaging technology that can directly assess circulation in the skin by measuring hemoglobin (Hb) distribution and oxygenation.15 SFDI has been demonstrated in a number of applications to quantify circulation—including flap perfusion and burn assessment.16 17 SFDI was also compared with current methods of non ...
