摘要： A system and method for unattended monitoring of blood flow using an array of transmitter elements configured to transmit acoustic signals along a transmission direction; an array of receiver elements configured to receive acoustic signals originating from the array of transmitter elements, wherein the array of transmitter elements is arranged approximately orthogonal to the array of receiver elements and wherein each receiver element is configured to provide an output signal; an electronics system comprising a transmitter control subsystem configured to adjust the transmission direction, a receiver control subsystem configured to selectively activate and deactivate receiver elements, thus defining an acoustic aperture, an analog adder circuit, and signal processing circuitry; a fastener to position the elements on a patient; and a processor in communication with the electronics system and configured to enable self-alignment of transmitted acoustic signals based on received acoustic signals and determine a blood flow parameter.

摘要： A method and system for using ultrasound for evaluating pressure of a vessel of a user, the method including: providing an ultrasound system configured to be placed at a body region proximal the vessel of the user, generating a correlation between a set of push pulse parameters and a set of push pulse-dependent values associated with the vessel, wherein generating the correlation includes providing a push pulse and determining a push pulse-dependent value based on the push pulse, generating a pressure value from the vessel based on the correlation, and generating a pressure waveform from the pressure value and a set of supplemental pressure values.
