[Segmentation of MR tomograms for quantitative volume estimation].

Abstract

MR tomography yields better contrasts for soft tissues than other imaging methods. This allows a reliable measurement of the volume of brain structures, in particular for the ventricular system and e. g. structures in hydrocephalic states. Therefore a method is proposed for segmentation and volume estimation of MR tomograms that is implemented via a computer program. This method provides an accurate determination of the volume tested on multiple-slice-images of normal patients and a phantom. The substantial features and possibilities of this program usable for all kinds of structures in MR-tomograms are explained here in detail.
