Three-dimensional ultrasonic imaging system

Abstract

The invention provides a three-dimensional ultrasonic imaging system which comprises an ultrasonic probe, a camera, a positioning module, an ultrasonic scanner and a computing module; wherein the camera is attached to the ultrasonic probe; the positioning module is placed within the viewfinder range of the camera; the ultrasonic scanner provides ultrasonic images corresponding to each part of a body, and meanwhile, the camera provides real time video; and the computing module simultaneously collects scanned pictures and videos and conducts corresponding three-dimensional pictures generated by computing. The invention has the advantages of low cost and is capable of increasing the accuracy of three-dimensional ultrasonic imaging space tracking.

Description

technical field [0001] The invention relates to a three-dimensional ultrasonic imaging system. Background technique [0002] Recently, the emphasis on 3D diagnostic practice has resulted in the rapid development of 3D ultrasound equipment. Compared to CT and MRI imaging, 3D ultrasound is a low-cost solution for obtaining stereo imaging. In addition, its operation does not require intensive training and radiation protection. And its hardware is detachable and potentially portable. Three-dimensional ultrasound imaging has been widely used in the examination or diagnosis of diseases such as abnormal fetus, lymph nodes and heart. [0003] A number of different techniques have recently been developed for 3D ultrasound imaging. In view of the acquisition methods, they can be divided into four categories: 2D transducer arrays, mechanical scanners, and freehand scanning methods with and without position information. [0004] Systems of arrays of 2D transducers can provide a lar...

AI Technical Summary

Problems solved by technology

[0004] Systems of arrays of 2D transducers can provide large volumes of important 3D images in real time, but are expensive and not readily available

However, this type of equipment requires that the probe can move stably in one direction but cannot perform large-scale rotation and transformation during B-ultrasound scanning

Additionally, such devices cannot provide accurate distance or volume measurements due to errors introduced by movement measurements during data acquisition
