Abstract: A method for processing ultrasound signals including controlling emission transducers for M successive emissions of plane ultrasound waves having M different angles of emission, controlling N reception transducers in order to simultaneously receive N measurement time signals per emission, and obtaining a matrix [MR(t)] of ultrasound time signals, each coefficient MRi,j(t) of this matrix representing the measurement signal received by the i-th reception transducer caused by the j-th emission. It further includes performing singular-value decomposition of a matrix [FTMR(f)] of frequency signals obtained by transforming the matrix [MR(t)], and eliminating a portion of the singular values and reconstructing a denoised matrix [MRU(t)] of time signals on the basis of the singular values not eliminated.

Abstract: A method for acquiring signals via ultrasound probing including: controlling L emission transducers and N reception transducers in order to simultaneously receive, for each of M successive emissions, N measurement signals; obtaining a matrix of ultrasound time signals having a size of N×M. An initial matrix ([MC?]), having a size of L×M', for encoding the successive emissions is previously defined for a number M? of successive initial emissions strictly greater than M. A calculation of acoustic field is carried out for each of the M? initial emissions. A reduced encoding matrix ([MC]), having a size of L×M, is obtained by removal of M??M columns of the initial encoding matrix ([MC?]) on the basis of a selection criterion applied to the M? calculations of acoustic fields. Finally, the control of the L emission transducers for the M successive emissions is encoded using the reduced encoding matrix ([MC]).
