Visualization of anatomical structures of epigastric organs by use of automatically segmented 3-D ultrasound image volumes--first results.

The detection and the staging of tumors and their metastases in parenchymatous organs of the epigastric organs today is improved by the enormous increase of imaging system's efficiency. For an increasing number of findings, which shall be dissected in intention to cure, the feasibility of diagnostics and therapy-planning based on sonograms was investigated. In 3-D US image volumes of approx. 20 patients, characteristic anatomical structures (e.g., vessels, abscesses, tumors) were detected by specifically adapted automatic computer-based segmentation and visualized. The detection of pathological findings, their quantification and their spatial assignment to anatomical main structures was essentially simplified by 3-D image acquisition and 2-D and 3-D visualization of segmented images.
