Organ-specific enhancement filter for robust segmentation of medical images
Abstract:
An imager (10) and a reconstruction processor (12) generate an intensity image (14). A region containing a target volume is identified (20) and limited (24). A classifier (30) operates on the voxels in the limited volume with an enhancement filter to generate an enhanced image, such as an image whose voxel values represent a probability that each voxel is in the target volume. A segmentation processor (40) segments the enhanced image to identify the surface of the target volume to generate a segmented image which is displayed on a monitor (52) or used in a radiation therapy planning system (54).
Abstract(Chinese):

成像器（10）和重建处理器（12）产生强度图像（14）。 识别包含目标体积的区域（20）并限制（24）。 分类器（30）通过增强滤波器对有限体积中的体素进行操作以生成增强图像，例如其体素值表示每个体素在目标体积中的概率的图像。 分割处理器（40）分割增强图像以识别目标体积的表面以产生显示在监视器（52）上或在放射治疗计划系统（54）中使用的分割图像）。
