  • Title: Extract echo signal in HFR imaging system.
    Author: Peng H, Wang J, Han X, Zhang S.
    Journal: Ultrasonics; 2006 Dec 22; 44 Suppl 1():e89-91. PubMed ID: 16857231.
    Abstract:
    Ultrasonic high frame rate (HFR) method was developed by Jianyu Lu in 1997. This method constructs images in frequency domain; the spectrum of space domain objects is calculated based on the spectrum of echo signals, and the image is obtained by using IFFT (inverse fast Fourier transform). Because of this imaging process, the echo signal from each individual scatterer cannot be obtained directly. In this paper, we present a method, which can pick up the echo signal of every scatterer in HFR imaging method. Computer simulation has been performed to verify our method. With the new method we have developed, many other imaging methods, such as Doppler blood flow and elastic imaging, can be easily combined with HFR method to give more information of the imaged objects.
