Abstract：Objective To achieve image reconstruction from the ultrasound radio-frequency (RF) signal to the ultrasonic B mode for the
subsequent follow-up diagnostic studies. Methods Taking a frame of RF data as the research object, the RF data from VINNO 70 was
reconstructed by low frequency filtering, dynamic quadrature demodulation, bandpass filtering and downsampling, dynamic display
range compression and scanning display imaging using MATLAB. Results Image was reconstructed successfully from the ultrasound
RF signal to the ultrasonic B mode. Conclusion The successful reconstruction of ultrasound B mode is of great significance in the
extraction and analysis of the lesion characteristic signal eigenvalue.
