3D Modelling and Printing Technology to Produce Patient-Specific 3D Models [PDF]

Heart, Lung and Circulation, 2019
A comprehensive knowledge of mitral valve (MV) anatomy is crucial in the assessment of MV disease. While the use of three-dimensional (3D) modelling and printing in MV assessment has undergone early clinical evaluation, the precision and usefulness of this technology requires further investigation.

3D ShapeNets: A Deep Representation for Volumetric Shapes

, 2015
3D shape is a crucial but heavily underutilized cue in today's computer vision systems, mostly due to the lack of a good generic shape representation. With the recent availability of inexpensive 2.5D depth sensors (e.g.

A comparison of 3D particle, fluid and hybrid simulations for negative streamers

, 2012
In the high field region at the head of a discharge streamer, the electron energy distribution develops a long tail. In negative streamers, these electrons can run away and contribute to energetic processes such as terrestrial gamma-ray and electron ...

Patient-specific 3D Printed Liver Models for Pre-operative Planning and Improved Patient Adherence [PDF]

, 2020
Project Background: 3D anatomical relationships in the liver are not always visually accessible for surgeons performing resections even with advanced imaging options. Firm understanding of these relationships is essential for timely procedures, which can

Impact of granulation effects on the use of Balmer lines as temperature indicators

, 2009
Balmer lines serve as important indicators of stellar effective temperatures in late-type stellar spectra. One of their modelling uncertainties is the influence of convective flows on their shape. We aim to characterize the influence of convection on the

3D modeling with silhouettes

ACM Transactions on Graphics, 2010
We present a new sketch-based modeling approach in which models are interactively designed by drawing their 2D silhouettes from different views. The core idea of our paper is to limit the input to 2D silhouettes, removing the need to explicitly create or position 3D elements. Arbitrarily complex models can be constructed by assembling them out of parts

Bridge Damage Detection and BIM Localization Methods Based on Image Recognition

Zhongwai Gonglu
To overcome insufficient information of 2D detection data in traditional bridge maintenance, which hinders precise decision-making, this study proposed an automated method based on deep learning and structure from motion (SfM) technology, which realized ...
