Three-Dimensional Imaging in Orthodontics [PDF]

open access: yesTurkish Journal of Orthodontics, 2018
Orthodontic records are one of the main milestones in orthodontic therapy. Records are essential not only for diagnosis and treatment planning but also for follow-up of the case, communicating with colleagues, and evaluating the treatment outcomes ...

Three-dimensional CT imaging in pediatric calvarial pathologies [PDF]

open access: yesDiagnostic and Interventional Radiology, 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.

Hyperspectral Three-Dimensional Fluorescence Imaging Using Snapshot Optical Tomography

open access: yesSensors, 2021
Hyperspectral three-dimensional (3D) imaging can provide both 3D structural and functional information of a specimen. The imaging throughput is typically very low due to the requirement of scanning mechanisms for different depths and wavelengths. Here we

Object-based 2D-to-3D video conversion for effective stereoscopic content generation in 3D-TV applications [PDF]

open access: yes, 2011
Three-dimensional television (3D-TV) has gained increasing popularity in the broadcasting domain, as it enables enhanced viewing experiences in comparison to conventional two-dimensional (2D) TV.

Three-Dimensional Particle Tracking via Bifocal Imaging

open access: yes, 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-

The virtual human face – superimposing the simultaneously captured 3D photorealistic skin surface of the face on the untextured skin image of the CBCT Scan [PDF]

open access: yes, 2013
The aim of this study was to evaluate the impact of simultaneous capture of the three-dimensional (3D) surface of the face and cone beam computed tomography (CBCT) scan of the skull on the accuracy of their registration and superimposition.

Motion and disparity estimation with self adapted evolutionary strategy in 3D video coding [PDF]

open access: yes, 2007
Real world information, obtained by humans is three dimensional (3-D). In experimental user-trials, subjective assessments have clearly demonstrated the increased impact of 3-D pictures compared to conventional flat-picture techniques. It is reasonable,

Increasing Temporal Resolution of 3D Transesophageal Ultrasound by Rigid Body Registration of Sequential, Temporally Offset Sequences [PDF]

open access: yes, 2010
A description of mitral valve function requires both an accurate anatomical description of the three-dimensional (3D) structure as well as a description of the leaflets' rapid motion.

Ultrafast quasi-three-dimensional imaging

open access: yesInternational Journal of Extreme Manufacturing, 2023
Understanding laser induced ultrafast processes with complex three-dimensional (3D) geometries and extreme property evolution offers a unique opportunity to explore novel physical phenomena and to overcome the manufacturing limitations. Ultrafast imaging

Robust three-dimensional best-path phase-unwrapping algorithm that avoids singularity loops [PDF]

open access: yes, 2009
In this paper we propose a novel hybrid three-dimensional phase-unwrapping algorithm, which we refer to here as the three-dimensional best-path avoiding singularity loops (3DBPASL) algorithm.
