Modeling the 3D Breast Surface Using Thermography
<p>Breast thermographies can show temperature distribution and detect abnormalities in the body on examination. This work shows an implementation allowing their used for three-dimensional (3d) models of the breast surface from their acquisition in five different angles. Firstly, breast segmentation is performed using U-Nets trained for each angle. Then, the segmented edges are transformed into parametric curves. Geometric transformation converts these curves from two-dimensional (2d) to a three-dimensional after proper rotations and translation of them. These 3D curves are described by B-splines curves and used to build a Rational Non-Uniform B-splines Surface (NURBS) for the breast region. Texture mapping is applied to project the frontal thermal data onto the 3d surface. A Likert scale-based survey was conducted with healthcare experts, and experienced academics to evaluate the final results and compare them with examples of the same persons. The results received high grades of approval and agreements.</p>

It is a three-dimensional MHD model, designed specially for the solar wind–magnetosphere–ionosphere system (4-6). The model possesses a high resolution in capturing MHD shocks and discontinuities and a low numerical dissipation in examining possible instabilities inherent in the system (4).</span></p> <p><span>The model uses a Cartesian coordinate system with the Earth’s center at the origin and X, Y, and Z axes pointing towards the Sun, the dawn-dusk direction, and the north, respectively. The size of the numerical box extends from 25 RE to –100 RE along the Sun-Earth line and from –50 RE to 50 RE in Y and Z directions, with 240×240×240 grid points and a minimum grid spacing of 0.2 RE. An inner boundary of radius 3 RE is set for the magnetosphere to avoid the complexities associated with the plasmasphere and large MHD characteristic velocity from the strong magnetic field (6). An electrostatic ionosphere shell with height-integrated conductance is imbedded, allowing an electrostatic coupling process introduced between the ionosphere and the magnetospheric inner boundary. The Earth’s magnetic field is approximated by a dipole field with a dipole moment of 8.06×1022 A/m in magnitude. The model is run to solve the whole system by inputting the real interplanetary conditions for the current event.</span></p>
