CT图像中大脑边界的提取与跟踪及其算法实现

Extraction and Tracing of Brain Edge in CT Image and Its Implementation Algorithm

在医学图像处理诸多领域中,边界跟踪具有非常重要的应用价值。以往的边界跟踪算法用来跟踪颅部CT图像中的复杂的大脑边界,经常出现误跟踪或异常中断。作者对已有算法进行了修改,以“知识制导”为特征的本算法准确性高,需要人工干预少。

Edge extraction and tracing in CT image are of very important application value in sever al areas of medical imaging,including 3-D display. The previous tracing algorithms for brain edge in CT scan images always resulted in fulse trace or unusual breaks. The authors modify the algorthm,its character is so called 'knowledge-guided 'searching. It is more accuracy and less manual intervention.
