Extracting bullous emphysema and diffuse emphysema in E.G. CT volume images of the lungs
Rafael Wiemker,Tobias Klinder +1 more
TL;DR: In this article, a 2D bullous emphysema projection image using second first indicia was generated, where the intensity of a contour of a bulla is based on the size of the bulla.

The impact of motion correction on lesion characterization in DCE breast MR images
TL;DR: It can be shown that the rate of motion outliers can be largely reduced by both rigid and elastic registration.

Visualizing tissue of interest in contrast image data
TL;DR: In this paper, a method for visual display of image data comprises: obtaining contrast image data having multiple voxels, wherein each voxel has an intensity value, determining the voxell belonging probability to the vessel; determining the hypoxicity of each Voxel; weighing the intensity by a corresponding probability of belonging to a vessel; weighing hypensitivity to a corresponding PPP probability; combining the weighted intensity values and the weighted hypersensitivity values with generating summary image data; and visual display for image summary data.

Image processing device and method for detecting line structures in an image data set
Rafael Wiemker,Tobias Klinder +1 more
TL;DR: In this paper, an image processing device for detecting line structures in an image data set is presented. But the device comprises a model definition unit (12) for defining a line model of a line structure to be detected, said line model comprising a number of voxels, a calculation unit (14) for calculating, per voxel of interest, several correlation values of a correlation between the line model and an image area around it, wherein each correlation value is calculated, and a determining unit (15) for determining the maximum correlation value from calculated correlation values and the corresponding
