Three-dimensional ultrasonic imaging method for two-dimensional ultrasonic image set reconstruction

Abstract

The invention discloses a three-dimensional ultrasonic imaging method for two-dimensional ultrasonic image set reconstruction. The method comprises the following steps that a linear array ultrasonic sensor is used for emitting ultrasonic signals to a target three-dimensional space, collecting the ultrasonic signals and reconstructing two-dimensional ultrasonic images of the target three-dimensional space; an ultrasonic sensor is rotated freely and moves horizontally, and the two-dimensional ultrasonic images of the target three-dimensional space at different angles and in different positions are reconstructed; the position and angle information of the ultrasonic sensor in the moving and rotating processes is detected through a displacement sensor and an angle sensor; in combination with the position and angle information of the ultrasonic sensor, the corresponding two-dimensional ultrasonic images are positioned in the three-dimensional space; a three-dimensional ultrasonic image is reconstructed through a two-dimensional ultrasonic image set.
