The “diabetic foot” can become a serious complication.

Diabetic foot syndromes or diabetic foot 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 the tissue in the legs and feet is supplied poorly. Often 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. 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 naked eye, can be identified.

Hyperspektrale Aufnahme eines Diabetischen Fußes, bei dem dargestellten Fuß handelt es sich um ein positives Beispiel für die Wundversorgung, da die Oxygenierung und NIR-Perfusion sehr gut sind. Der Fuß wurde mit Plasma und Kollagen-Wundauflagen behandelt. Die markierten Bereiche zeigen die Möglichkeit der Quantifizierung

Hyperspectral uptake of a diabetic foot, the foot depicted is a positive example of wound care since oxygenation and NIR perfusion are very good. The foot was treated with plasma and collagen wound dressings. The marked areas show the possibility of quantification
