Ultrasonic image automatic annotating method and system based on three-dimensional virtual image

Abstract

The invention provides an ultrasonic image automatic annotating method and system based on a three-dimensional virtual image. The method comprises the following steps: displaying a three-dimensional virtual organ image and an ultrasonic probe image, displaying a two-dimensional image annotated image and a textual annotating sequence, selecting an organ reference point, recording the spatial position information of the reference point, modifying the spatial position information of the reference point in real time, automatically modifying the three-dimensional organ virtual image and the ultrasonic probe image in real time according to the position information of the reference point and an ultrasonic probe, automatically updating the two-dimensional image annotated image and the textual annotating sequence in real time, and displaying a two-dimensional ultrasonic image and an ultrasonic image sequence in three-dimensional space. The method and the system automatically annotate the position of the ultrasonic image during the process of ultrasonic detection scanning, do not need manual input, reduce repetitive work of operators, and also improve the annotation accuracy. 本发明提供一种基于三维虚拟图像的超声图像自动标注方法及系统,该方法包括以下步骤：显示三维虚拟器官图像和超声探头图像；显示二维图像化标注图像和文字性的标注序列；选择器官参考点；记录参考点的空间位置信息；实时修改参考点的空间位置信息；根据参考点和超声探头的位置信息实时自动修改三维虚拟器官图像和超声探头图像；实时自动更新二维图像化标注图像和文字性的标注序列；同时显示二维超声图像和三维空间中的超声图像序列。实施本发明的基于三维虚拟图像的超声图像自动标注方法及系统在进行超声探测扫描的过程中自动对超声图像的位置进行标注，无需手动输入，减少了操作者的重复性工作，同时还提高了标注的准确性。
