Hyperspectral Imaging to Define Amputation Limits in Vascular and Thyroid Diseases

The aim of the project is to develop a hyperspectral camera for use in surgery for amputations due to diabetic foot syndrome/PAOD and for resections of the thyroid gland.

The aim of the joint project "Hyperlimit-CAM: Hyperspectral Imaging for the Definition of Amputation Limits in Diabetic Foot Syndrome/PAOD and in Resection of the Thyroid/Parathyroid Glands" is to develop a hyperspectral camera that will serve as a direct aid in surgery for amputations due to Diabetic Foot Syndrome/PAOD as well as for resections of the thyroid gland.

In the sub-project "Amputation Medicine,"  the determination of amputation limits in diabetic foot syndrome/PAOD is to be objectified and thus facilitated with the help of hyperspectral imaging. Basic investigations into the spectroscopic differentiation of vital and dead tissue are being carried out at the Wismar University of Applied Sciences. Basic investigations into the spectroscopic differentiation of vital and dead tissue are being carried out at the Wismar University of Applied Sciences.

In the "Thyroid" sub-project, the aim is to facilitate tissue segmentation during resections of the thyroid or parathyroid gland. Algorithms for segmenting the thyroid, parathyroid and lymph nodes are being developed at Wismar University. Here, as in the sub-project "Amputation Medicine", hyperspectral remission data are used. In addition, the autofluorescence emission of the parathyroid gland will be detected in the NIR range by exciting it with light in the red to near-infrared wavelength range. The correspondingly adapted hyperspectral camera with a switchable illumination unit is being developed by the project partner, Diaspective Vision.

Finally, clinical studies with the project partners are to prove that the use of this imaging method optimally supports the surgeon intraoperatively and leads to better treatment success (outcome).

The joint project with the consortium leader, Dr. Axel Kulcke, Diaspective Vision GmbH is being carried out together with the scientific partners, the University Medical Centre Greifswald, Clinic and Polyclinic for General Surgery, Prof. Dr. Andreas Hoene, and the Klinikum Südstadt Rostock, Clinic for General, Visceral, Thoracic and Vascular Surgery, Dr. Bernd Kortmann, MD.
