TL;DR: This preliminary study on the clinical practicability of aspiration tests showed promising results in terms of reproducibility (reliability) and clinical use (feasibility), which will provide further insights on its usefulness in clinical practice and in the detection of substantial changes of the cervix in pregnancy indicative for threatened preterm birth or cervical insufficiency.
Journal ArticleDOI
An automatic nonrigid registration for stained histological sections
TL;DR: A hierarchical nonrigid registration algorithm able to align images, which contain minor image artifacts, and which can be applied to various multicontrast elastic registration problems in medical imaging and may be extended to three dimensions.
Journal ArticleDOI
A procedure to simulate coronary artery bypass graft surgery
TL;DR: A computational methodology for the simulation of traditional CABG surgery is proposed, and the effect of two clinically relevant parameters on the artery and graft responses, i.e., incision length and insertion angle for a given graft diameter are analyzed.
Journal ArticleDOI
Arterial clamping: Finite element simulation and in vivo validation
TL;DR: This study is the first to describe a finite element simulation of the clamping of a rat abdominal aorta with occlusion and in vivo validation, showing the importance of finite element modeling in understanding the relation between mechanical loading and damage mechanisms.
Journal ArticleDOI
On Fiber Dispersion Models: Exclusion of Compressed Fibers and Spurious Model Comparisons
TL;DR: The purpose of this paper is to develop a method for excluding compressed fibers within a dispersion for the generalized structure tensor (GST) model, and to draw attention to several erroneous and misleading statements in the literature concerning the relative values of the GST and the angular integration models.
