algorithms or region growing are well-known, but they are In this paper we address the problem of ultrasound volume data segtnentation by means of active contours. The segmentation is performed on an slic~by-slice basis but exploiting the high correlation that exists across nearby slices. We have used active rays to alleviake the computational load of the(More)
The visualization of diffusion tensor fields remains a challenging topic. A representation based on volume rendering of a scalar field is presented. The method uses the tensor to correlate a noise field in the direction of greater diffusivity while preserving the high frequency components of the noise field in transversal diffusion directions.
A 61-year-old female developed a rapidly progressive pan-cerebellar syndrome. During the initial assessment, which included a brain magnetic resonance scan and examination of the cerebrospinal fl uid (CSF), the studies were negative. The study using immunofl uorescence of the patient's serum and the patient's CSF with sections of rat cerebellum showed(More)
