Patent ID: 7679988

Claim:
A sound-wave imaging method, comprising: at least one emission step during which a first array of transducers is caused to emit at least one ultrasound excitation wave presenting a certain central emission frequency f c and focused on at least one target point in a target medium, and said excitation wave is caused to pass through a reverberant solid object prior to reaching the target medium, each transducer of the first array being secured to said reverberant solid object and said reverberant solid object being adapted to give rise to multiple reflections of the excitation wave that passes therethrough and to cause an impulse wave of duration 1/f c entering into said solid object to lead to sound emission to the target medium taking place over a duration of not less than 10/f c ; at least a reception step wherein echoes emitted by the target medium in response to the excitation wave are received; and an imaging step wherein an image of at least a portion of said target medium is built based on the received echoes.
