Application of Multiple Iso-Surface Rendering to Improvement of Perceived Depth in Transparent Stereoscopic Visualization

In recent years the application of 3D video endoscopic systems in clinical routine, especially in the field of endoscopic surgery, has increased steadily. The number of 3D video endoscopic systems used in the operating theatre today is obviously lower than the number of established traditional 2D video endoscopic systems. The hesitant application of the new technology can be mainly explained by the lack of evaluation of its influence on the surgical procedure and on patient benefit as well as by the need for specific economic analysis. The starting point for our investigations was to analyze the influence of 3D video endoscopy on endoscopically guided manipulations in general. In order to achieve quantitative statements we performed laboratory experiments using human factors analyzing methods. In the next step we performed clinical field studies of the application of 3D video endoscopic systems for a side-by-side comparison of 2D and 3D systems. These studies showed that the use of 3D video endoscopy has an improving influence on endoscopically guided surgical manipulations as well as on the intraoperative procedures. We also found that spatial visual perception of stereoscopic images of 3D video systems may cause problems for some users. For the validation of stereoscopic visualization systems we additionally studied the influence of isolated technical, optical, and physiological parameters on visual perception as well as on transposition into visually guided manipulations. Detailed results of these investigations concerning the influence of 3D video endoscopy on binocular perception are presented.

Abstract Three-dimensional, multiplanar sonography, using a volume data set acquired with a 3D probe, has revolutionized ultrasonographic imaging and takes sonographers to a new perception of the fetus in 3 dimensions. Real time scanning, until the late nineties only possible in B-mode, can now be performed in 3D with up to 40 frames/sec. Fetal neurology emerged as a new perinatal research field with the 4D visualization of fetal behavior. Doppler ultrasound, diversified and refined from continuous wave and pulsed Doppler to Color – and Power Doppler, when added to 3D sonography, creates fascinating options of noninvasive fetal vascular mapping (sonoangiography) and vascular assessment of placenta. The diagnostic and demonstrative potential of an acquired 3D volume data set can be maxed with the help of postprocessing and rendering software. After storage, the evaluation of fetal 3D data sets can happen without the patient, with the option of specialist consultation, using telemedicine. In the article, the new 3D “modes” like surface rendering, maximum mode, 3D Color and Power Doppler, STIC, volume rendering, and glass body rendering, are described and illustrated in their display of normal fetal anatomy.

Object Surface

Bottom and concave shapes on object surface are difficult to reconstruct in image-based visual hull method. In this paper, we propose a simple but efficient method to solve these problems in regular image-based visual hull framework. With the help of a simple image acquiring platform which involves a glass and a mirror, we can capture images of the object from both upper and lower side at the same time. Using these images, silhouette cones necessary for reconstructing the bottom and the concave surfaces could be generated. Therefore the final rendering result of the object can be significantly improved in accuracy and reality, especially in the parts of bottom and concaves.

Different Levels

New technologies and techniques allow novel kinds of visualizations and different types of 3D visualizations are constantly developed. We propose a categorization of 3D visualizations and, based on this categorization, evaluate two versions of a space-time cube that show discrete spatiotemporal data. The two visualization techniques used are a head-tracked stereoscopic visualization (‘strong 3D’) and a static monocular visualization (‘weak 3D’). In terms of effectiveness and efficiency the weak 3D visualization is as good as the strong 3D and thus the need for advanced 3D visualizations in these kinds of tasks may not be necessary.

Abstract Practical use of medical simulation system with virtual reality technology is expected because of the learning of the operation procedure. We have therefore developed a neurosurgical simulation system for minimally invasive surgery. Our system is composed of PC and one or two haptic interfaces. Operator can pick up the region of interest to specify the disease portion from DICOM format image data, then three-dimensional model have made by volume and surface rendering with this data. In the next step, system estimates and indicates on CRT the minimally invasive path from the head surface to the disease target that was picked up beforehand by this system which retains healthy human’s three-dimensional atlas data. Finally, the operator can perform a virtual surgery operation by the haptic interface that has been connected to PC, and can cut off an exact or approximate portion of the disease. The operator can feel the resistance from this virtual object. This operation process can be recorded for medical doctors to review later.
