Abstract
A method for measuring a viscoelastic parameter of an organ, includes emitting ultrasonic shots by an ultrasonic transducer; receiving by the transducer and recording the reflected ultrasonic signals; determining a viscoelastic parameter of the organ based on the recorded ultrasonic signals. The ultrasonic shots are formed by K groups of shots, separated temporally, K being greater than or equal to 1. Each K group is formed by the repetition, with a rate of PRF2, of MK blocks of ultrasonic shots, MK being greater than or equal to 1; each MK block is composed of N ultrasonic shots, N being greater than or equal to 1, PRF1 being the rate of emission of the N shots when N is chosen greater than 1; the N ultrasonic shots are distributed over P frequencies, P being between 1 and N, at least two ultrasonic shots belonging to two different blocks having different frequencies.
