A high frame rate (HFR) ultrasonic imaging method developed by Jianyu Lu has been attracting attention in the related imaging area. Because a special weighting on the received signal is needed to implement this method, the imaging system is complicated. This paper presents a new kind of theroetical analysis for the HFR imaging system in view of the angular spectrum concept. Based on the study, the special weighting process can be replaced by Fourier transform. Computer simulation demonstrates the correctness of the analysis. It shows that the constructed images by the new method have the same high quality as those obtained by using the original HFR method while the system implementation is greatly simplified.
