Paper Abstract

In this paper we present a method for interactive analysis of non-segmented medical volume data. We discuss both different rendering methods for visualization and different possibilities for interaction in relation to segmentation results. Furthermore, the adaptive region growing approach is applied to both segmentation of a structure of interest, as well as generation of transfer function for volume rendering of the same structure. The adaptive region growing method is based on the statistical evaluation of 3D-neighbourhood. The method is used for determination of a homogeneity criterion for the structure of interest. Subsequently this criterion is used for segmenting of data and for generating of an initial transfer function for volume rendering. We utilize this for displaying a hybrid 3D-visualization of the segmented structure and the specific gray-value interval of original data. Based on this rendering we discuss possibilities for user-guided validation of segmentation results, based on the variation of several rendering parameters.
