Three-dimensional sonography: transparent presentation of volumetric scans

By presenting a coordinated sequence of 3D projections of ultrasound information, the impression of a 3D object rotating in space is obtained. Thus, orientation and spacial distribution of 3D objects can be easily recognized and analyzed. By means of this reconstruction technique, transparency and 3D character are emphasized during the perception. Diagnostic interpretation far beyond the possibilities of a simple static projection is achieved. Using this technique in oral-maxillo-facial surgery we found improvement in diagnostic possibilities and diagnostic safety in the following applications: tumor diagnostics in oncology, improved localization in surgery, scanning of the temporomandibular joint, volume calculation of organs, volume calculation of arteriosclerotic plaques, localization and treatment diagnostics in lithotripsy. The possibilities in the different applications are presented in selected cases. Our experiences show that 3D sonography is now at the point where clinical use in different applications is possible. Further clinical trials will determine their benefits in daily clinical practice.
