Three-Dimensional Particle Tracking via Bifocal Imaging
, 2007 We introduce a bifocal imaging method that enables three-dimensional (3D) tracking of both fluorescent and nonfluorescent particles. We accomplish this by simultaneously imaging a focused plane, for in-plane position (x,y), and a defocused plane, for out-

Checking the consistency of 3D geological models [PDF]
Geoscientific Model DevelopmentThree-dimensional geological modelling algorithms can generate multiple models that fit various mathematical and geometrical constraints. The results, however, are often meaningless to geological experts if the models do not respect accepted geological ...

Three-Dimensional Printing: is it useful for Cardiac Surgery? [PDF]
Brazilian Journal of Cardiovascular Surgery, 2020 Introduction: The medical use of three-dimensional (3-D) images has been a topic in the literature since 1988, but 95% of papers on 3-D printing were published in the last six years.

Three dimensional (3D) imaging techniques in orthodontics-An update
Journal of Family Medicine and Primary Care, 2020 3D imaging is a technique which develops or creates the impression of depth within an image by deploying 2D data into 3-dimensional format. To aid in quality regulating processes for industrial purposes, 3D imaging has become an extremely valuable factor.

Three-dimensional CT imaging in pediatric calvarial pathologies [PDF]
, 2013 In children with suspected cranial pathologies, three-dimensional (3D) computed tomography (CT) imaging is superior to other modalities. It can help differentiate actual pathology from normal or variant appearances.

Optimizing Image Focus for Shape From Focus Through Locally Weighted Non-Parametric Regression
IEEE Access, 2019 Shape from focus is a passive optical technique that uses multiple images with different focus levels. To compute the sharpness of each pixel in the image sequence, obtained by translating the object plane at a constant step size along the optical axis ...

Segmentation of three dimensional images [PDF]
Proceedings. 1985 IEEE International Conference on Robotics and Automation, 2005 In this paper, we describe the fundamental differences between three-dimensional (range) images and two-dimensional (luminance) images. A number of problems arise which are unique to range data, including in particular a strong sensitivity to quantization effects.

A three-dimensional inverse finite-element method applied to experimental eddy-current imaging data. [PDF]
, 2006 Eddy-current techniques can be used to create electrical conductivity mapping of an object. The eddy-current imaging system in this paper is a magnetic induction tomography (MIT) system.

Three-dimensional imaging and scanning: Current and future applications for pathology
Journal of Pathology Informatics, 2017 Imaging is vital for the assessment of physiologic and phenotypic details. In the past, biomedical imaging was heavily reliant on analog, low-throughput methods, which would produce two-dimensional images.
