| dc.description.abstract | Tomographicmedical imaging techniques have become more popular in recent years. The wide availability of CT,MRI and Ultrasound inmost large hospitals results in a rapidly increasing number of examinations with these devices. The State of The Art Report summarises the application of techniques developed over the recent years for visualising volumetric medical data common in modern medical imaging modalities such as CT, MRA, MRI, Nuclear Medicine, 3D-Ultrasound, Laser Confocal Microscopy etc. Although all of the modalities listed above provide ”slices of the body”, significant differences exist between the image content of each modality. The focus of the Report is be less in explaining algorithms and rendering techniques, but rather to point out their applicability, benefits, and potential in the medical environment. In the first part, methods for all steps of the volume visualization pipeline from data preprocessing to object display are reviewed, with special emphasis on data structures, segmentation, and surface- and volume-based rendering. Furthermore,multimodalitymatching, interventionrehearsal, and aspects of image quality are discussed. In the second part applications are illustrated fromthe areas of craniofacial surgery, traumatology, neurosurgery, radiotherapy, and medical education. Furtherly, some new applications of volumetricmethods are presented: 3D ultrasound, laser confocal datasets, and 3D-reconstruction of cardiological datasets, i.e. vessels as well as ventricles. These new volumetric methods are currently under development but due to their enormeous application potential they are expected to be clinically accepted within the next years. | en_US |
