Patent ID: 10386335

Abstract:
A method including control of M emission transducers for L successive ultrasound plane wave emissions having L different emission angles, control of N reception transducers for simultaneously receiving N measurement time signals for each emission and reconstitution of an imaged zone by calculating, at each point, a value resulting from a processing of the measurement time signals received. The reconstitution of the imaged zone includes calculating L′×N flight times, L′≤L, each flight time tl,n being the time taken for the l-th plane wave, the emission zone of which includes the point considered, where 1≤l≤L′, to be received by the n-th reception transducer, where 1≤n≤N, passing through the point considered according to a predetermined propagation mode, and coherent summing L′×N instantaneous values taken, respectively, by the L′×N measurement time signals received corresponding to the L′ emissions, at the L′×N flight times.
