IEEE Open Journal of Instrumentation and Measurement, 2022 Phantoms are used to evaluate, calibrate, and compare the performance of electrical impedance tomography (EIT) systems. This paper presents a dynamic thorax-like mesh phantom, which mimics the changes in electrical conductivity distribution within a ...

Parallel smoothing of quad meshes [PDF]
The Visual Computer, 2009 For use in real-time applications, we present a fast algorithm for converting a quad mesh to a smooth, piecewise polynomial surface on the Graphics Processing Unit (GPU). The surface has well-defined normals everywhere and closely mimics the shape of Catmull–Clark subdivision surfaces.

Shrinking tube mesh: combined mesh generation and smoothing for pathologic vessels
Current Directions in Biomedical Engineering, 2020 We present a mesh generation algorithm which is able to produce smooth meshes from point clouds derived from histological slices. In this work, the shrinking tube mesh generation is used on histologic images depicting pathologic vessels.

An efficient method to improve the quality of tetrahedron mesh with MFRC
Scientific Reports, 2021 In this paper, we proposed a novel operation to reconstruction tetrahedrons within a certain region, which we call MFRC (Multi-face reconstruction). During the existing tetrahedral mesh improvement methods, the flip operation is one of the very important

An Accurate Approximation of the Two-Phase Stefan Problem with Coefficient Smoothing
Mathematics, 2020 In this work, we consider the heat transfer problems with phase change. The mathematical model is described through a two-phase Stefan problem and defined in the whole domain that contains frozen and thawed subdomains.
