In this article, we present a new method for the generation of surface meshes of biological soft tissue. The method is based on the deformable surface model technique and is extended to histological data sets. It relies on an iterative adjustment towards polygonal segments describing the histological structures of the soft tissue. The generated surface… (More)
OBJECTIVE As an initial step to a complex reconstruction model for virtual surgery, the present study was carried out to provide data on the prenatal cleft lip and palate uvular muscle in eight specimens. METHOD Serial sections of viscerocrania of 18 aborted embryos and fetuses were studied microscopically and segmented manually. Registration,… (More)
Occlusional performance of sole endoluminal stenting of intracranial aneu-rysms is controversially discussed in literature. Simulation of blood flow has been studied to shed light on possible causal attributions. The outcome however largely depends on various free parameters which all have considerable impact on simulation results. The current study is… (More)
In this paper an approach for developing a temporal domain ontology for biomedical simulations is introduced. The ideas are presented in the context of simulations of blood flow in aneurysms using the Lattice Boltzmann Method. The advantages in using ontologies are manyfold: On the one hand, ontologies having been proven to be able to provide medical… (More)
The occlusional performance of sole endoluminal stenting of intracranial aneurysms is controversially discussed in the literature. Simulation of blood flow has been studied to shed light on possible causal attributions. The outcome, however, largely depends on the numerical method and various free parameters. The present study is therefore conducted to find… (More)

Occlusional performance of sole endoluminal stenting of intracra-nial aneurysms is controversially discussed in literature. Simulation of blood flow have been studied to shed light on possible causal attributions. The outcome however largely depends on the degree of accuracy of geometry representation as provided by the means of segmentation. The current… (More)
