Abstract
In this work, we proposed a novel normalized filed autocorrelation function (g1) –based functional ultrasound (fUS). We introduced a metrics derived from g1 function of ultrasound signals that is inversely proportional to blood flow and validated g1-fUS with in vivo experiments of whisker stimulation. Results show that g1-fUS is able to detect blood flow speed change in response to enhanced neural activity and is not affected by clutters compared to power Doppler based fUS, indicating that g1-fUS is a good candidate for whole brain functional imaging in small animals.
