摘要： An improved method for processing image voxel data representative of 3-dimensional images of a colon to remove the effects of tagged stool. The method uses parabolic curve intensity-gradient models representative of the intensity and gradient relationship at a transition between two material types as a function of the fraction of the two materials for each of a plurality of two-material type classes, including a gas-tissue transition model, a gas-stool transition model and a stool-tissue transition model. The voxels are classified into one of a plurality of substance classes including tagged stool, gas, tissue and unknown classes. The unknown class voxels are processed as a function of the intensity-gradient models to classify the unknown class voxels into one of the two-material type classes. The two-material type class voxels are processed as a function of the associated intensity-gradient model to determine the fractions of materials in each voxel. The intensity of the two-material type class voxels is then adjusted as a function of the fraction of the materials in the voxels.

摘要： A method for displaying colonography images includes presenting a series of oblique images of the colon at sequential locations along the colon centerline. Each image is generally centered on the centerline, presents a field of view generally perpendicular to the centerline, and is oriented with the bottom of the colon down.

摘要： A method for processing and displaying colonography image data. First distance tissue pixels representative of tissue within a first distance of gas pixels representative of gas are processed with a first window/level setting to generate a first setting set of image pixels. Second distance tissue pixels representative of tissue within a second distance of the gas pixels are processed with a second window/level setting to generate a second setting set of image pixels. The second distance is a distance greater than the first distance. A colonography image including both the first and second setting sets of image pixels is then displayed.
摘要翻译：一种处理和显示结肠图像数据的方法。代表气体的气体像素的第一距离内的组织的第一距离组织像素用第一窗口/等级设置进行处理，以生成图像像素的第一设置集合。代表气体像素的第二距离内的组织的第二距离组织像素用第二窗口/等级设置进行处理，以产生图像像素的第二设置集合。第二距离是大于第一距离的距离。然后显示包括图像像素的第一和第二设置组的结构图像。
