摘要: 针对B 型超声系统中采用硬件电路完成数字扫描变换缺乏灵活性且成本较高的问题,采用Rtheta插补法以及帧相关降噪实现了凸阵式超声数字扫描变换。结果表明,采用本方法能够快速地显示图像,最终图像显示帧频为30 f/s,满足B型超声系统的实时显像要求。

关键词: 数字扫描变换, B超, 坐标变换, 插补处理

Abstract: We employ Rtheta interpolation and frame correlation to achieve convex ultrasonic digital scan conversion for bad flexibility and higher cost of hardware digital scan conversion in Bultrasonic system.Results show that it can quickly display images and satisfy the requirement of realtime image display, final video frame frequency of 30 f/s.

Key words: conversion of coordinates, digital scan conversation, interpolation, B-ultrasonic system
