Automatic segmentation of cerebral cortex in magnetic resonance imaging (MRI) is a challenging problem in understanding brain anatomy and functions. The difficulty is mainly due to variable brain structures, various MRI artifacts and restrictive body scanning methods. This paper describes a hybrid model-based method for obtaining an accurate and(More)
The p53 gene is a growth control gene, abnormalities of which have been implicated in a variety of cancers. Recently wild-type p53 has been shown to exist in two interchangeable conformational variants, which can be distinguished by specific p53 monoclonal antibodies. One conformation acts as a suppressor (PAb240-/PAb1620+) and one acts as a promoter(More)
Simulation and three-dimensional visualization of object motion is a prerequisite for any surgical planning system. Orbital hypertelorism is a disease, which is most commonly associated with craniofacial malformations. We have developed a surgical planning system for planning and evaluation of orbital hypertelorism surgery. In our system CT-based virtual(More)
Visualizing efficiently volumetric data still remains a challenge in many fields such as medical imaging and scientific visualization. Monte Carlo volume rendering is a novel and efficient visualization technique for very large datasets. However, when taking into account depth cueing, the volume rendering integral becomes complex, and it is difficult to(More)
