  • Method and apparatus for extracting cardiac information from acoustic information acquired with an ultrasound device
    Patent number: 6312382
    Abstract: The present invention provides a method and apparatus for processing acoustic information obtained with an ultrasound device to generate cardiac information, such as, for example, a patient's heart rate. In accordance with the present invention, an ultrasound system is utilized to image a patient's heart to obtain acoustic information relating to the patient's heart. The acoustic information is converted into electrical information, which is then processed to extract a particular feature of interest therefrom, such as, for example, the patient's heart rate. In accordance with the preferred embodiment of the present invention, processing of the electrical signals comprises the steps of generating a time-series from a series of image frames and then performing a spectral analysis on the time-series. The features of interest are then easily extracted from the results of the spectral analysis.
