Abstract :
A method to greatly simplify the high-frame-rate (HFR) imaging system using a rotation of coordinates in image reconstruction was developed. A theory of Fourier image reconstruction was also developed and both in vitro (on an ATS539 tissue-mimicking phantom) and in vivo (on a human heart) experiments were performed to verify the theory.
