Abstract (en)
[origin: WO2018109314A1] This method (700) of processing ultrasound signals comprises the control (702) of emission transducers for M successive emissions of plane ultrasound waves exhibiting M different angles of emission, the control (702) of N reception transducers to simultaneously receive N temporal measurement signals per emission, and the obtaining (704) of a matrix [MR(t)] of ultrasound temporal signals, each coefficient MRi,j(t) of this matrix representing the measurement signal received by the i-th reception transducer due to the j-th emission. It furthermore comprises a decomposition into singular values (710) of a matrix [FTMR(f)] of frequency signals which is obtained (708) by transforming the matrix [MR(t)], an elimination (712) of some of the singular values and a reconstruction (714) of a denoised matrix [MRU(t)] of temporal signals on the basis of the non-eliminated singular values.
