System and method for measuring pressure using ultrasound

A method for measuring pressure using an ultrasound system, the method comprising:

• (a) acquiring ultrasound data from a region-of-interest containing an interface between a first medium and a second medium, wherein the ultrasound data are acquired using an ultrasound system by:
• generating with the ultrasound system one or more transmitted ultrasound waves directed towards the region-of-interest;
• and
• detecting one or more ultrasound waves reflected from the region-of-interest in response to the one or more transmitted ultrasound waves interacting with vibrations caused at the interface between the first medium and the second medium by displacements propagating in the first medium, wherein the one or more ultrasound waves reflected from the region-of-interest encode the vibrations caused at the interface by the displacements propagating in the first medium and wherein the one or more ultrasound waves reflected from the region-of-interest do not capture ambient and environmental noise in the region-of-interest;
• (b) accessing the ultrasound data with a computer system in order to process the ultrasound data, generating output as at least one of displacement or pressure data indicative of displacement or pressure measurements associated with the displacements propagating in the first medium;
• and
• (c) outputting the at least one of the displacement or pressure data to a user using the computer system, wherein the at least one of the displacement or pressure data have reduced noise based on the ambient and environmental noise not being captured in the ultrasound data.
