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.
