Hyperspectral imaging has been explored for clinical applications in various medical disciplines. Based on our experiences, the potential of this versatile imaging method as well as pitfalls and limitations of current approaches are discussed. The use of reference samples and simple image modeling strategies are suggested to avoid misinterpretation and achieve a more conclusive image interpretation.
Hyperspectral imaging (HSI) is a new emerging modality for noncontact assessement of tissue perfusion parameters. This study includes investigations on monitoring perfusion changes of the hand during a modified Allen test and cuff occlusion test, on the influence of the skin tones during HSI-measurements and the feasibility of HSI monitoring of intraoral free flaps
Hyperspectral imaging to monitor perfusion parameters during the Allen test was performed in 20 volunteers. Clear differences in tissue oxygenation and hemoglobin index during rest, occlusion and reperfusion were visually and computationally evident.
