Diabetic foot syndromes or diabetic foot, respectively, develops in relation with diabetes as the underlying condition. Mainly, people with type-2-diabetes are affected. Because of the disease, the blood vessels are compromised and, amongst others, the tissue in the legs and feet is supplied poorly. Oftentimes, this is accompanied by peripheral nerve damage (neuropathy). With that in mind, in many cases, diabetes patients develop poorly healing, chronic wounds, when suffering relatively harmless wounds to their extremities. In severe cases, this leads to amputations, which are an indicator for the possible fatal cause of the illness.

With the HSI-technology, it is possible to detect complications, choose the appropriate therapy and monitor the healing process early on. It is the first non-invasive imaging method, which supports assessments of the status of tissue perfusion within seconds. It uses not only the visible, but also the invisible near infrared part of the spectrum. Accordingly, positive as well as negative courses of wound development, which cannot be seen with the mere eye, can be identified.
