【摘要】 在医学图像配准各种方法中,基于灰度的方法具有精度较高、稳健性强、不需要预处理等优点而被广泛使用,但是这类 方法也存在着计算量大的缺点。文章在分析传统刚体坐标变换的基础上,提出了一种新的坐标变换的快速算法,可以较 大地提高图像坐标变换速度而不影响计算精度,有利于图像配准的临床实时性。更多还原

【Abstract】 Intensity-based registration methods are popular registration methods due to their high accuracy, robustness having no need for preprocessing. But they are computational expensive. By analyzing the classical transformation, we present a new transformation method, which speeds up the transformation procedure without lossing the accuracy of registration result.更多还原
