In the B-mode sector scan ultrasonic imaging system, the raw image is in polar coordinates, therefore, it is main tasks of image pre-processing to achieve image coordinate transform and interpolation.
在B型超声机械扇形扫描成像当中，原始图像信号是以极坐标的形式输出的，对图像进行实时坐标变换和漏点插补是图像预处理所要解决的主要问题。
Conventional ultrasonic imaging methods such as B-scan and C-scan couldn't meet the requirements of composite inspection.
传统超声b扫描和C扫描成像方法不能满足复合材料的检测需求。
In ultrasonic B-scan imaging testing, pseudo-images which lead to inaccurate results can often ap-pear due to the influence of ultrasonic multiple reflections.
超声b扫描成象检测中，由于超声多次反射的影响经常出现伪象，导致检测结果不准确。
