Posterior body elongation is a widespread mechanism propelling the generation of the metazoan body plan. The posterior growth model predicts that a posterior growth zone generates sufficient tissue volume to elongate the posterior body. However, there are energy supply-related differences between vertebrates in the degree to which growth occurs concomitantly with embryogenesis. By applying a mu...

Volumetric Layer Segmentation Using a Generic Shape Constraint with Applications to Cortical Shape Analysis Xiaolan Zeng Yale University 2000 A novel approach has been developed in this thesis for the problem of segmenting volumetric layers, a type of structure often encountered in medical image analysis. This approach is aimed towards the use of structural information to enhance the performanc...

OBJECTIVE To determine the effect of 3 differing transfusion techniques on survival of autologous canine RBCs. DESIGN Prospective, blinded study. SETTING University Teaching Hospital. ANIMALS Nine healthy dogs. INTERVENTIONS Three distinct preparations of RBCs, each representing ~1% of red cell mass, were generated for each dog by biotinylation of RBCs at varying biotin densities. Label...

INTRODUCTION Mammographic density, the white radiolucent part of a mammogram, is a marker of breast cancer risk and mammographic sensitivity. There are several means of measuring mammographic density, among which are area-based and volumetric-based approaches. Current volumetric methods use only unprocessed, raw mammograms, which is a problematic restriction since such raw mammograms are normal...

Volumetric colon wall unfolding is a novel method for virtual colon analysis and visualization with valuable applications in virtual colonoscopy (VC) and computer-aided detection (CAD) systems. A volumetrically unfolded colon enables doctors to visualize the entire colon structure without occlusions due to haustral folds, and is critical for performing efficient and accurate texture analysis on...

AIM To evaluate the new Octavius 4D system for patient specific quality assurance and to study the correlation between plan complexity and gamma index analysis in patient specific quality assurance of VMAT using the Octavius 4D system. BACKGROUND McNiven (2010) proposed a study to evaluate the utility of a complexity metric, the Modulation Complexity Score, to evaluate the relationship of the...
