Abstract
(EN) An ultrasound imaging system includes an array of acoustic elements configured to transmit ultrasound energy at a first transmit speed and receive echoes associated with the ultrasound energy transmitted at the first transmit speed. The system further includes a processor circuit in communication with the array of acoustic elements. The processor is configured to generate a plurality of multilines based on the received echoes, determine a second transmit speed, determine a set of transmit focus delays based on the second transmit speed, adjust the plurality of multilines using the set of transmit focus delays, generate an image based on the adjusted plurality of multilines, and output the generated image to a display in communication with the processor circuit.
(FR) L'invention concerne un système d'imagerie par ultrasons qui comprend un réseau d'éléments acoustiques configuré pour émettre de l'énergie par ultrasons à une première vitesse d'émission et recevoir des échos associés à l'énergie par ultrasons émise à la première vitesse d'émission. Le système comprend en outre un circuit processeur en communication avec le réseau d'éléments acoustiques. Le processeur est configuré pour générer une pluralité de lignes multiples sur la base des échos reçus, déterminer une seconde vitesse d'émission, déterminer un ensemble de retards de focalisation d'émission sur la base de la seconde vitesse d'émission, ajuster la pluralité de lignes multiples à l'aide de l'ensemble de retards de focalisation d'émission, générer une image sur la base de la pluralité ajustée de lignes multiples, et délivrer en sortie l'image générée vers un afficheur en communication avec le circuit processeur.
