摘要：
Provided are an ultrasonic imaging method, a system and a device, relating to the technical field of ultrasonics. Said method comprises: performing the following steps for each pixel point: acquiring echo data received by a plurality of array elements； acquiring the coordinates of a pixel point in a Cartesian coordinate system, the coordinates of receiving array elements for receiving the echo data of the pixel point, and the coordinates of transmitting array elements for transmitting ultrasonic waves to the pixel point； converting the coordinates of the receiving array elements in the Cartesian coordinate system into the coordinates of the receiving array elements in a polar coordinate system； calculating a delay time of the pixel point according to the coordinates of the pixel point and the transmitting array elements in the Cartesian coordinate system and the coordinates of the receiving array elements in the polar coordinate system； and obtaining, according to the delay time and the echo data, an intensity value of the pixel point under beam forming. By computationally converting the coordinates of the receiving array elements in a Cartesian coordinate system into coordinates in a polar coordinate system, the present technical solution is able to complete beam forming under the transmission of convex-array plane waves at single/multiple angles, so as to realize ultrafast convex-array ultrasonic imaging.L'invention concerne un procédé, un système et un dispositif relevant du domaine technique des ultrasons. Le procédé selon l'invention comprend : la mise en œuvre des étapes suivantes pour chaque point de pixel : acquérir les données d'écho reçues par une pluralité d'éléments de matrice ； acquérir les coordonnées d'un point de pixel dans un système de coordonnées cartésiennes, les coordonnées des éléments de matrice récepteurs qui reçoivent les données d'écho du point de pixel, et les coordonnées des éléments de matrice transmetteurs qui transmettent des ondes ult
