APPARATUS FOR MEASURING PRESSURE IN A VESSEL USING ACOUSTIC IMPEDANCE MATCHING LAYERS |
摘要 |
The apparatus for measuring pressure inside a vessel using acoustic impedance matching layers may include an ultrasound exciting unit attached to the outer surface of the vessel wall that generates ultrasonic waves inside of the vessel. A first acoustic impedance matching layer attached to the inner surface of the vessel wall increases the transmitting efficiency of the ultrasonic waves. An ultrasound receiving unit attached to the outer surface of the vessel wall receives an ultrasonic signal traveling inside the vessel. A second acoustic impedance matching layer attached to the inner surface of the vessel wall increases the transmitting efficiency of the ultrasonic waves. A control unit connected to the ultrasound exciting unit controls the excitation signal transmitted into the ultrasound exciting unit. A pressure measuring unit connected to the control unit measures an internal pressure of the vessel based on the excitation signal and the received ultrasonic waves.
