至今还没有人将折扇形式引入当代艺术，它似乎只能体现闲情逸致。

Up to today, no other artists have introduced such an art form into the modern arts as it seems to be simply an expression of leisurely and carefree mood.

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。

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.
