Reconstruction of the human cerebral cortex from MR images is a fundamental step in human brain mapping and in applications such as surgical path planning. In a previous paper, we described a method for obtaining a surface representation of the central layer of the human cerebral cortex using fuzzy segmentation and a deformable surface model. This method,(More)
Introduction Characterizing normal versus abnormal cortical geometry is an important goal of human brain mapping. This task proves difficult because of the convoluted nature of the cortical surface. Difficulties arise in both identifying topological landmarks and obtaining reliable quantitative measurements. A standard measurement method is to trace sulcal(More)
The long-term aim of this project is to noninvasively measure aortic blood pressure and aortic blood flow using a portable ultrasonic device. It is envisioned that a small array of ultrasonic crystals will be placed on the suprasternal notch of the neck. The ultrasound beam will be continually positioned onto the aortic arch by a computer. Wall motion will(More)
