扇形超声扫描仪数字扫描变换器的研制

A digital scan converter for ultrasonic sector scanners

本文介绍一种用于Ｂ型扇扫超声成像的数字扫描变换器。它采用一种针对有效像素点变换的技术，有效地降低了对电路速度的要求，从而提高了数字扫描变换器的性能，有利于高级图像处理技术的实现。

A digital scan converter for B-mode sector scanner is presented in this paper. A new technique only converting effective pixels is adopted so that the high speed circuit has not to be used in this DSC. Thus, the property of digital scan converter is impr-oved and advanced image processing techniques can be used.
