Methods and apparatus for pulsatility-mode sensing

Abstract

According to some aspects, there is provided a device configured to determine a measure of brain tissue motion in a brain, comprising: at least one transducer configured to transmit an acoustic signal to at least one region of the brain and receive a subsequent acoustic signal from the at least one region of the brain; and at least one processor configured to: determine the measure of brain tissue motion in the at least one region of the brain by processing the subsequent acoustic signal, wherein processing the subsequent acoustic signal comprises filtering the subsequent acoustic signal. Filtering the subsequent acoustic signal may comprise one of spatiotemporal filtering, signal decomposition, tissue tracking, and/or spectral clustering.
