A Critical Evaluation of Human Perception in Conventional Flap Monitoring Versus Spatial Frequency Domain Imaging

INTRODUCTION: Detection of failing tissue fl aps before clinically apparent changes are noticeable has the potential to improve post-operative flap management and salvage. This study demonstrates a model to quantitatively compare clinical appearance, as recorded via digital camera, with spatial frequency domain imaging (SFDI), a non-invasive imaging technique utilizing wide fi eld patterned illumination to generate images of tissue perfusion.
