THREE-DIMENSIONAL ULTRASONIC IMAGING METHOD AND SYSTEM BASED ON THREE-DIMENSIONAL OPTICAL IMAGING SENSOR

摘要

A three-dimensional ultrasonic imaging system and method based on a three-dimensional optical imaging sensor. The system comprises: an ultrasonic probe (01) for performing ultrasonic scanning on a region of interest of a target; a two-dimensional ultrasonic imaging device (05) for generating a two-dimensional ultrasonic image of the region of interest of the target on the basis of the ultrasonic scanning; a three-dimensional optical imaging sensor (03) for obtaining distance information from at least one marker (11) within a visual range (04) of the three-dimensional optical imaging sensor (03) to a camera of the three-dimensional optical imaging sensor (03) and image information of the marker (11); a spatial information processing module (06) for obtaining three-dimensional spatial information of the ultrasonic probe (01) on the basis of the distance information and the image information; and a three-dimensional reconstruction module (07) for reconstructing a three-dimensional ultrasonic image on the basis of the three-dimensional spatial information and the two-dimensional ultrasonic image. The system and method can flexibly reconstruct a three-dimensional ultrasonic image with low costs and a small volume, and can effectively avoid interference.
