Superconducting Nanowire Single-Photon Detectors Excel in DCS Applications . BOSTON, Aug. 24, 2021 — Researchers from Massachusetts General Hospital and MIT Lincoln Laboratory have developed a superconducting nanowire single-photon detector (SNSPD)-based diffuse correlation spectroscopy (DCS) device. The instrument demonstrated a high signal-to-noise ratio and high sensitivity for blood flow. This study marks one of the first-ever applications of SNSPDs in a biomedi...
