【摘要】 数字扫描变换器是B超诊断仪中的一个关键部件。本文提出了一种新颖的数字扫描变换器设计方案。它以递推算法和圆插补技术为基础,采用小存储器结构,不仅获得了失真小的高质量图像,而且具有部件成本低、硬件规模小等特点。实践证明,它具有很高的性能价格比与推广应用价值。文中详细说明了系统的工作原理,并给出了有关的实验结果。更多还原

【Abstract】 Digital Scan Converter (DSC) is an important component in modern B-mode ultrasonic diagnostic scanner. A new DSC is presented in this paper which is based on the recursive algorithm,circular interpolation and small image memory structure.The DSC has the advantages of low cost ,simple hardware as well as providing high quality images. It is worth to use it in various B-mode scanner as it has high performance/cost ratio. The system principle is described in detail and the experimental result is given in this paper.更多还原
