A calibration-informed deep learning model for three-dimensional particle reconstruction of volumetric particle image velocimetry

The Physics of Fluids
Accurately reconstructing three-dimensional particle fields is essential in fluid velocity measurement research. This study addresses the limitations of current three-dimensional (3D) particle reconstruction methods, such as computational efficiency ...

Are Magnetic Resonance Imaging-Generated 3Dimensional Models Comparable to Computed Tomography-Generated 3Dimensional Models for Orbital Fracture Reconstruction? An In-Vitro Volumetric Analysis

Journal of Oral and Maxillofacial Surgery, 2023
Magnetic resonance imaging (MRI) is being increasingly considered as an alternative for the evaluation and reconstruction of orbital fractures. No previous research has compared the orbital volume of an MRI-imaged, three-dimensional (3D), reconstructed, and virtually restored bony orbit to the gold standard of computed tomography (CT).To measure the ...

Two-dimensional computational method for generating planar electrode patterns with enhanced volumetric electric fields and its application to continuous dielectrophoretic bacterial capture.

Lab on a Chip, 2019
An array of microfabricated interdigitated electrodes (IDEs) is one of the most commonly used forms of electrode geometry for dielectrophoretic manipulation of biological particles in microfluidic biochips owing to simplicity of fabrication and ease of ...

Color-Encoded Illumination for High-Speed Volumetric Scene Reconstruction

arXiv.org
The task of capturing and rendering 3D dynamic scenes from 2D images has become increasingly popular in recent years. However, most conventional cameras are bandwidth-limited to 30-60 FPS, restricting these methods to static or slowly evolving scenes ...

Time-resolved computed tomography of the liver: retrospective, multi-phase image reconstruction derived from volumetric perfusion imaging

European Radiology, 2013
To assess feasibility and image quality (IQ) of a new post-processing algorithm for retrospective extraction of an optimised multi-phase CT (time-resolved CT) of the liver from volumetric perfusion imaging.Sixteen patients underwent clinically indicated perfusion CT using 4D spiral mode of dual-source 128-slice CT.

Contralateral Autologous Augmentation in DIEP Flap Reconstruction: Employing Computed Tomography Angiography and Volumetric Analysis for Preoperative Planning

Plastic & Reconstructive Surgery
Summary: Autologous reconstruction accounts for approximately 20% of all breast reconstruction procedures. In cases of unilateral reconstruction, contralateral breast augmentation using autologous tissue can be performed to improve symmetry, and it is a viable option for patients interested in having more volume relative to ...

Distribution and volumetric assessment of initial approximal caries lesions in human premolars and permanent molars using computer-aided three-dimensional reconstruction

Archives of Oral Biology, 2000
Serial sections from 21 extracted premolars and permanent molars, divided into three age groups (group 1, 10-19 years; group 2, 20-39 years; group 3, 50-69 years.), were viewed by polarized light microscopy for reconstruction of the caries lesions. The volumes of the lesional body and the transparent zone, and the volumes of early dentinal lesions were
