Abstract
This two-dimensional Fourier transform ultrasound imaging method includes by controlling transmitting and receiving transducers: obtaining M matrices MR≤m≤M, of sampled ultrasonic time signals; two-dimensional Fourier transforming each matrix MRto obtain M spectral matrices FTMR; converting each spectral matrix FTMRto obtain M spectral images FTI; combining the M spectral images FTIand two-dimensional inverse Fourier transforming the resulting spectral image FTI to obtain an ultrasound image I. The conversion includes taking into account a change of propagation mode during a backscatter, by adding a parameter characterizing this change of mode in equations (SYS) of change of reference frame, and/or taking into account a reflection against a wall, by adding a phase shift term in a relation (REL) of matrix transformation.
