Measuring microvascular sO2 using visible light OCT

Researchers from Northwestern University have used the SuperK EXTREME supercontinuum laser to demonstrate a method to measure microvascular sO2 and simultaneously provide three-dimensional anatomical tissue morphology using visible light optical coherence tomography. The SuperK was used as a broadband source for the Fourier domain OCT setup enabling transverse and axial resolutions of 7 μm and 1.3 μm, respectively.
