Superconducting nanowire single-photon detectors: Next big thing in blood flow measurement
In a new study, researchers from Massachusetts General Hospital developed a superconducting nanowire single-photon detector (SNSPD)-based diffuse correlation spectroscopy (DCS) device with 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 biomedical setting. In order to function properly, the brain requires a …
