Comparisons of breast support requirements during overground and treadmill running have yet to be explored. The purpose of this study was to investigate 3D breast displacement and breast comfort during overground and treadmill running. Six female D cup participants had retro-reflective markers placed on the nipples, anterior superior iliac spines and clavicles. Five ProReflex infrared cameras (...

Computer generated 3D models of buildings are an important component of many computer graphics applications. Rapid and easy-to-use modelling techniques are often more important than the ability to create precise and detailed geometry. We present a sketch-based modelling tool for the rapid creation of rough 3D building models. The algorithm analyses the sketch input, extracts shape and detail in...

A full three dimensional study of a tensile test on a sample made of polymerbonded propellant is presented. The analysis combines different tools, namely, X-ray microtomography of an in situ experiment, image acquisition and treatment, 3D volume correlation to measure three dimensional displacement fields. It allows for global and local strain analyses prior to and after the peak load. By study...

Actual applications of the energy absorbers showed that actual loads are not applied in the form of pure axial compression, pure bending or pure torsion. In reality, an energy absorber component may be subjected to combined loading of compression, bending and torsion. A number of previous articles have investigated the behavior of energy absorbers under oblique loading. In such cases, the obliq...

MRI provides a valuable tool for noninvasive evaluation of myocardial wall motion. Recently, multi-phase 2D DENSE MRI was developed to quantify cardiac strain in mice at high spatial and temporal resolution [1, 2]. DENSE methods for 3D displacement encoding have also been investigated [3]. Typically, these methods entail multiple acquisitions that are time consuming. In this project, we aimed t...

A novel approach to determine the structure of nanoscale crystals in three dimensions is proposed by the use of coherent x-ray Fourier transform holography in Bragg geometry. The full internal description is directly obtained by a single Fourier transform of the 3D intensity hologram. Together with the morphology, Bragg geometry gives access to the 3D displacement field within the crystal. This...

This paper describes displacement mapping technique that is used in 3D graphics to add detail on the object’s surface. There are various approaches for implementing it that suit different usages. Most common approaches are explained and shortcomings for each are listed. An adaptive view dependant tessellation algorithm is looked at more closely and some hardware related issues are also discusse...

BACKGROUND Set-up errors are an inherent part of radiation treatment process. Coverage of target volume is a direct function of set-up margins, which should be optimized to prevent inadvertent irradiation of adjacent normal tissues. The aim of this study was to evaluate three-dimensional (3D) set-up errors and propose optimum margins for target volume coverage in head and neck radiotherapy. M...

In this paper, we address the problem of surface tracking in multiple camera environments and over time sequences. In order to fully track a surface undergoing significant deformations, we cast the problem as a mesh evolution over time. Such an evolution is driven by 3D displacement fields estimated between meshes recovered independently at different time frames. Geometric and photometric infor...

We present an intensity based deformable registration algorithm for 3D ultrasound data. The proposed method uses a variational approach and combines the characteristics of a multilevel algorithm and the properties of ultrasound data in order to provide a fast and accurate deformable registration method. In contrast to previously proposed approaches, we use no feature points and no interpolation...
