METHOD AND APPARATUS FOR OBTAINING A TISSUE DOPPLER IMAGE WHICH IS PHOTOGRAPHED BY AN ULTRASONIC WAVE

摘要

PURPOSE: A method and apparatus for obtaining a tissue Doppler image are provided to efficiently track and observe a cardiac function in congenital and acquired heart diseases by quantitatively evaluating a heart rate.;CONSTITUTION: An ultrasonic signal is transmitted to an object (S100). An ultrasonic response signal is received from the object (S200). The received ultrasonic response signal is filtered by using a tunable filter (S300). The frequency of the received ultrasonic response signal is estimated based on the filtered data (S400). A tissue Doppler image is generated based on the estimated frequency (S500).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S100) Ultrasonic signal is transmitted to an object; (S200) Ultrasonic response signal is received from the object; (S300) Received ultrasonic response signal is filtered by using a tunable filter; (S400) Frequency of the received ultrasonic response signal is estimated based on the filtered data; (S500) Tissue Doppler image is generated based on the estimated frequency
