Regional Tissue Perfusion Index (RTPI): A New Optical-Based Metric for Quantifying Regional Tissue Perfusion

2025-09-10

Abstract excerpt

<title>Abstract</title> <p>Purpose Accurate, continuous assessment of regional tissue perfusion remains a significant clinical challenge, as most existing modalities are invasive, indirect, or impractical for routine monitoring. Near-infrared spectroscopy (NIRS) has been widely adopted to assess tissue oxygenation; however, conventional NIRS-derived indices are insufficient surrogates for true perfusion and often...
