In this paper,we propose an algorithm for the semiautomatic segmentation of medical image series based on the combination of the live wire algorithm and the active contour model.We modify the traditional live wire algorithm by combining it with the region growing method and obtain accurate segmentation of one or more slices in a medical slice series by the live wire algorithm.Then the computer will segment the nearby slice using the active contour model.We introduced a gray scale model to the boundary points of the active contour model to record the local region characters of the desired object in the segmented slice and replace the external energy of the traditional active contour model with the energy decided by the gray scale model.A simple method based on the idea of the live wire algorithm is introduced for the reparation of the automatic segmentation result to guarantee the reliability of the result.Experiment shows that our algorithm can obtain the boundary of the desired object from a series of medical images quickly and reliably with only little user intervention.

本文介绍了一种结合livewire算法和活动轮廓模型的医学图像序列的分割方法 .我们通过把livewire算法和图像分割中一般的区域增长方法结合来改进livewire算法 ,并用改进后的算法来对医学图像序列中的单张或多张切片进行交互式的准确分割 .然后计算机利用活动轮廓模型来自动分割相邻的未分割切片 .我们通过在活动轮廓模型的边缘点中引入记录已分割物体边缘附近局部区域特征的灰度模型来把已分割切片中的物体与背景的局部区域特征带入相邻的未分割切片中 ,并用由灰度模型定义的区域相似性代替活动轮廓模型中的外能来引导边缘轮廓收敛到物体的实际边缘 .本文还介绍了一种基于livewire算法思想的简单的分割结果交互式修补方法 .实验表明我们的算法仅需少量用户交互就能快速准确的从医学图像序列中分割出感兴趣的物体 .

For common medical slices(e.g.CT or MR),the space between neighboring pixels in a slice is often smaller than the center-to-center slice separation,while in most 3D image processing,analysis and visualization tasks it requires voxels to be isotropic.Many interpolation techniques have been proposed for processing such data.The commonly used grey level interpolation can produce artifacts or blurred contours when two given slices shift considerably.More reasonable interpolation results is...

For common medical slices(e.g.CT or MR),the space between neighboring pixels in a slice is often smaller than the center-to-center slice separation,while in most 3D image processing,analysis and visualization tasks it requires voxels to be isotropic.Many interpolation techniques have been proposed for processing such data.The commonly used grey level interpolation can produce artifacts or blurred contours when two given slices shift considerably.More reasonable interpolation results is achieved by shape-based methods,especially the nonrigid registration based methods.Rueckert′s registration method is took to produce deformed data fields,and the method proposed by Lee is used to interpolate scattered data with multilevel B-splines.Compared with Penney′s method,this one produces almost the same result image with less computation time,further more,it can produce C~2-continuous images.

三维图像的处理和操作需要将一般的断层序列插值成为具有各坐标轴一致的分辨率的体数据,而目前最常用的线性插值方法在层间距较大时会导致图像边缘模糊和出现伪影。Penney根据现有的非刚体匹配方法,提出了利用图像形变场数据的插值算法,明显提高了层间插值的质量。本研究对Penney提出的算法进行了改进,用多分辨率B样条拟合插值方法替代Penney使用的最邻近直线插值方法,并将新算法的实验结果与原算法、线性插值进行了对比。新算法既保持了高质量插值又提高了计算速度,并且使生成的图像达到了C2平滑。此算法可用于精度要求比较高的体数据插值重建过程。
