… field D ) and F is a function that maps the eigenvalues,(51) F( D )= ∑ k=1 3 f k (λ k ) e ̂ k
e ̂ T k , where f k are scalar functions. Since the effect of the function F is only a weighting of …

Both post-mortem and neuroimaging studies have contributed significantly to what we know
about the brain and schizophrenia. MRI studies of volumetric reduction in several brain …

MRI-guided focused ultrasound (MRgFUS) surgery is a noninvasive thermal ablation method
that uses magnetic resonance imaging (MRI) for target definition, treatment planning, and …

… If F is chosen to be a computationally efficient lowpass filter, then the filter specified by (22) …
Kikinis, and F. Jolesz, “Threedimensional segmentation of MR images of the head using …

… This model assumed that the distribution of the probabilistic fractional segmentation in the
background class was F(x) ∼ Beta(α 0 β 0 ), while the distribution of the probabilistic fractional …

Sleep deprivation is known to impair a range of functions, including immune regulation and
metabolic control, as well as neurocognitive processes, such as learning and memory [1]. …

In contrast to acquisition-based noise reduction methods a postprocess based on anisotropic
diffusion is proposed. Extensions of this technique support 3-D and multiecho magnetic …

PURPOSE: To determine if focused ultrasound beams can be used to locally open the blood-brain
barrier without damage to surrounding brain tissue and if magnetic resonance (MR) …

Background. Data from postmortem, CT, and magnetic resonance imaging (MRI) studies
indicate that patients with schizophrenia may have anatomical abnormalities of the left temporal …

This study used quantitative volumetric magnetic resonance imaging techniques to explore
the neuroanatomic correlates of chronic, combat-related posttraumatic stress disorder (PTSD…
