Abstract
This method for imaging in real time the propagation of a mechanical wave in an acoustically propagative medium comprises steps of: a) emitting (1000) a mechanical wave in an acoustically propagative medium, using an acoustic source being placed in an emission region of the acoustically propagative medium, b) measuring (1002) voltage signal waveform values at a reception region, using an acoustic measurement unit; c) calculating (1004) acoustic field values in the acoustically propagative medium, between the emission region and the reception region, using a reconstruction algorithm implemented in a signal processing unit, and the signal waveform values measured during step b) d) generating an image, using an image generation device and using the calculated acoustic field values.
