Background: Many research and development efforts have been made for automated compliance checking of building designs with regulatory requirements, but there is a lack of a non-proprietary and user-understandable representation of building regulations to support automated compliance checking in the construction domain that is experimentally tested for understandability and reading speed. Metho...

PURPOSE To determine the impact of retrospectively ECG-gated multi-detector row CT (MDCT) on three-dimensional (3D) visualization of the bronchial tree and virtual bronchoscopy (VB) as compared to non-ECG-gated data acquisition. MATERIALS AND METHODS Contrast-enhanced retrospectively ECG-gated and non-ECG-gated MDCT of the chest was performed in 25 consecutive patients referred for assessment...

Laterally spreading tumors may sometimes evade detection by colonoscopy. This study aimed to evaluate the use of image-enhanced endoscopy for visualizing laterally spreading tumors of the nongranular type. We reviewed consecutive patients with 47 non-granular-type laterally spreading tumors that had been examined using white-light imaging, autofluorescence imaging, narrow-band imaging, and chro...

Interactions become essential in Visualization because they enable users to adapt the visual representation to their own needs allowing them to explore the underlying information space. By using non-conventional devices, they face a wider fan of interaction possibilities to explore their data. But, there is still not an agreed base theory to describe the processes involved in the visualization ...

PURPOSE Three-dimensional (3D) magnetic resonance phase contrast imaging (PC-MRI) allows non-invasive diagnosis of pulmonary hypertension (PH) and estimation of elevated mean pulmonary arterial pressure (mPAP) based on vortical motion of blood in the main pulmonary artery. The purpose of the present study was to compare the presence and duration of PH-associated vortices derived from different ...

Scientific visualization techniques have been used to probe and understand better the physics of non-equilibrium flows. A visualization methodology for non-equilibrium flow simulations using 3-D velocity distribution functions(VDFs) is illustrated in application to various non-equilibrium flow problems. A one-dimensional normal shock wave problem is considered for two different upstream Mach nu...

Deposition of ceramic nanoparticles (dispersed in a non-aqueous suspension) on in-plane electrodes and under the influence of AC electric fields in the frequency range of 0.01 Hz - 10 kHz is investigated. Analysis of the particle response to the applied field is a difficult task due to the mutual effect of electric- and hydrodynamic force which are present in the system. In this work, however, ...

This paper describes a prototype of a visualization system which is designed to support radiologists during invasive and non-invasive magnetic resonance imaging. We use pre-acquired and real time data in our system to provide an intuitive and flexible visualization of the process and the results of the examination. In the presented system, we combine the advantages of both surface rendering and...
