摘要
A method embodiment includes generating, via a sensor of a computing device, a signal representing vibrations originating from a blood vessel of a subject and decomposing the signal into one or more first intrinsic oscillatory modes and one or more second intrinsic oscillatory modes. The one or more first intrinsic oscillatory modes have respective oscillation frequencies that are less than respective oscillation frequencies of the one or more second intrinsic oscillatory modes. The method includes obtaining an intensity spectrum of the one or more first intrinsic oscillatory modes over a range of frequencies and using the obtained intensity spectrum to determine a blood volume status of the subject. Another method embodiment includes using the one or more second intrinsic oscillatory modes to determine one or more mechanical properties of the blood vessel or tissue adjacent to the blood vessel.
