医学超声图象的处理与拼接

医学超声图象在临床上得到了广泛的应用，但由于超声图象存在着动态范围小，对比度差，而且噪声大和观察范围有限等缺点，影响了超声图象的临床诊断效果。本文提出了Ｂ超图象的自动匹配与拼接方法，实现了表现更大观察范围的Ｂ超图象，从而弥补了手工拼接中的精度低，误差大的缺陷。为提高图象的匹配与拼接精度，文中还讨论了图象的噪声抑制与灰度增强处理方法，提高了Ｂ超图象的再现质量

IMAGE CONNECTION AND ITS APPLICATION TO MEDICAL ULTRASONIC IMAGE

A set of new algorithms for image connection was presented. In order to improve quality of medical ultrasonic image, we adopted the adaptive weighted median filter to suppress the speckle noise and employed the adaptive histogram equalization to enhance the details. Then the image connection was performed using the image matching technique. Finally to get a seamless and smoothed connected image, we employed interpolating and smoothing operation. The experiment results and conclusions were also given.
