Three-dimensional ultrasonic detection method

Abstract

The 3D ultrasonic detection method includes the following steps: determining and fixing the part to be detected, determining the 3D coordinate system, moving the ultrasonic probe to the detected part and hand scanning to acquire the type-B ultrasonic scanned image transmitted to the computer, locating the probe position synchronously and transmitting to the computer, showing the type-B ultrasonic scanned images in the 3D coordinate system to obtain the 3D space image, determining the boundary mark image, and analyzing the boundary mark image quantitatively. The present invention can perform real-time detection without need of reconstructing the integral stereo image. 本发明提供一种三维超声波检测方法，包括下述步骤：确定所关心的部位并将其固定；定制整体三维坐标系；将超声波探头移动至所关心的部位并进行徒手扫描以采集B型超声波扫描图像并传送至计算机；与前一步骤同步，通过测定该超声波探头位置的空间定位装置获得该超声波探头的空间定位数据并传送至计算机；将B型超声波扫描图像显示在整体三维坐标系下，以获得整体三维坐标系下的各B型超声波扫描图像的三维空间单片图像；在整体三维坐标系下的B型超声波扫描图像的所述三维空间单片图像中确定具有界标的界标图像；以及对所述的界标图像进行定量分析。由此，依据本发明可以无需重构组织的整个体积图像而可现场、实时、快速地进行检测。
