Abstract: A method of modifying a segmented volume is disclosed herein. The method includes generating a reduced-resolution segmentation mask including a segmented region. The method includes performing a morphological erosion on the segmented region to form an eroded region and performing a morphological dilation on the eroded region to form a dilated region. The method also included identifying a leakage region in the segmented volume based on the dilated region and removing the leakage region from the segmented region to form an updated segmented volume.

Abstract: A new oral polymeric controlled release formulation suitable for the once-a-day administration of valproate compounds, such as divalproex sodium, has been discovered. This formulation exhibits significant advantages over the sustained release valproate formulations of the prior art. This formulation minimizes the variation between peak and trough plasma levels of valproate over a 24 hour dosing period. This formulation follows a zero-order release pattern thus producing essentially flat plasma levels of valproate, once steady-state levels have been achieved. This results in a significantly lower incidence of side effects for patients consuming such a formulation.

Abstract: The disclosed embodiments relate to characterizing or quantifying an element or composition of interest within an imaged volume. In accordance with one embodiment, high and low energy images are acquired of a volume of interest using a polychromatic emission source. The high and low energy images are processed to generate monochromatic images. Based on the observed attenuation within the monochromatic images, one or more elements or compositions of interest are characterized within the imaged volume.
