Functional localization is a concept which involves the application of a sequence of
geometrical and statistical image processing operations in order to define the location of …

It has been shown that the difference of squares cost function used by standard realignment
packages (SPM and AIR) can lead to the detection of spurious activations, because the …

This paper describes several experiments that prove that standard motion correction
methods may induce spurious activations in some motion-free fMRI studies. This artifact …

The ordinary sample correlation coefficient is a popular similarity measure for aligning
images from the same or similar modalities. However, this measure can be sensitive to the …

A global optimization technique for image registration, based on mutual information, that can
be used in conjunction with a multi-resolution paradigm is described. This technique …

The popularity of magnetic resonance (MR) imaging in medicine is no mystery: it is non-
invasive, it produces high quality structural and functional image data, and it is very versatile …

Image registration is used widely in applications for mapping one image to another. Existing
image registration methods are either feature-based or intensity-based. Feature-based …

Purpose: Dysembryoplastic neuroepithelial tumors (DNTs) are a group of glioneuronal
supratentorial and intracortical lesions often associated with the early onset of intractable …

The subtraction of interictal from ictal SPECT coregistered to 3-dimensional (3D) MRI
(SISCOM) and 18F-FDG PET are 2 techniques that are involved in the definition of the …

The main objective of this work was to study the functional markers of the clinical response
to cholecystokinin tetrapeptide (CCK-4). Twelve healthy male subjects were challenged with …
