About

The aim of this study is to find out whether hyperspectral imaging enables bronchus stump and bronchus anastomosis oxygenation.

Full description

The bronchus before lung resection and the bronchus stump or bronchus anastomosis, respectively, are investigated. The hyperspectral imaging camera head is placed and aligned over the surgical (camera and object distance: 30 cm for all measurements). The Field of view is illuminated by 8 halogen spots (20 W each) and 100 wavelengths in the wavelength range from 500 to 1000 nm were applied. The software calculates the tissue oxygenation [%] , organ-hemoglobin-index, near-infrared-Index and the tissue-water-index of the investigated tissue. The study was designed to investigate tissue oxygenation in the superficial (app. 1mm) and deeper layers (app. 4-6mm) of the bronchus before and after lung resection.
