This paper describes a software framework, based on virtual reality, for real-time immersive visualization of and interacting with flow simulation data. The objective of applying virtual reality techniques to flow simulation data is to explore the efficacy of combining the real-time interaction afforded by virtual reality based interactions with conventional visualization algorithms to gain bet...

Methods Patients with a Fontan circulation were prospectively consented to undergo three dimensional phase contrast (4Dflow) imaging during a clinical cardiac MRI evaluation which also included standard two dimensional phase contrast (2D-PC) imaging of all pertinent vessels. Differential pulmonary blood flow was calculated using standard 2D-PC imaging of the right and left pulmonary arteries (R...

We present a new method for finding the temperature profile of vertically stacked threedimensional (3D) digital integrated circuits (ICs), as shown in Fig. 1. Using our model, we achieve spatial thermal resolution at the desired circuit level, which can be as small as a single MOSFET. To resolve heating of 3D ICs, we solve non-isothermal device equations self-consistently with lumped heat flow ...

The objective of this study is to quantify the detailed three-dimensional (3D) pulsatile hemodynamics, mechanical loading, and perfusion characteristics of a patient-specific neonatal aortic arch during cardiopulmonary bypass (CPB). The 3D cardiac magnetic resonance imaging (MRI) reconstruction of a pediatric patient with a normal aortic arch is modified based on clinical literature to represen...

In this study, the nonlinear effect of contactless bubble–bubble interactions in inertial micropumps is characterized via reduced parameter one-dimensional and three-dimensional computational fluid dynamics (3D CFD) modeling. A pump model developed to account for bubble-bubble interactions, accuracy assessed commercial volume CFD software, FLOW-3D. The FLOW-3D validated against experimental bub...

BACKGROUND AND PURPOSE We present a relatively simple approach that physicians can use to reconstruct cerebral vessels as 3D numerical grids or computational replicas. The method accurately duplicates their geometry to provide computer simulations of their blood flow. METHODS Initial images were obtained by using any medical imaging technique, such as MR angiography, CT angiography, or 3D dig...

Inductive coupling links (ICLs) are gaining traction as an alternative to through silicon vias (TSVs) for 3D integration, promising high-bandwidth connectivity without the inflated fabrication costs associated with TSV-enabled processes. For power-efficient ICL design, optimisation of the utilised physical inductor geometries is essential, however typically necessitates the use of finite elemen...

Introduction In the past few years the use of musculoskeletal ultrasound (MSUS) in pediatric rheumatology has proven to be better than clinical examination in detecting synovitis. Beside standard power doppler ultrasound (PDUS), vascularization of the tissues can be assessed using 3D/4D PD sonography. Using this technique, we can now assess a virtually reconstructed vascular tree within a volum...

The purpose of computing is insight, not numbers – Hamming We propose to develop and evaluate computational modeling, simulation, visualization, and data-analysis tools and apply them to specific scientific areas involving time-varying flows near complex 3D boundary shapes. Tools will be developed in a highly multidisciplinary manner, incorporating insights and knowledge from the biological dom...
