Three-dimensional ultrasound matrix imaging
Nature Communications, 2023 AbstractMatrix imaging paves the way towards a next revolution in wave physics. Based on the response matrix recorded between a set of sensors, it enables an optimized compensation of aberration phenomena and multiple scattering events that usually drastically hinder the focusing process in heterogeneous media.

Three-Dimensional Imaging in Orthodontics [PDF]
Turkish 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. Recently, two-dimensional (2D) imaging technology, such as cephalometric and panoramic radiographs and ...

Three Dimensional Imaging of the Nucleon [PDF]
Few-Body Systems, 2018 We study the Wigner distributions of quarks and gluons in light-front dressed quark model using the overlap of light front wave functions (LFWFs). We take the target to be a dressed quark, this is a composite spin $-1/2$ state of quark dressed with a gluon. This state allows us to calculate the quark and gluon Wigner distributions analytically in terms

Three dimensional imaging of short pulses [PDF]
Optics Communications, 2004 We exploit a slightly noncollinear second-harmonic cross-correlation scheme to map the 3D space-time intensity distribution of an unknown complex-shaped ultrashort optical pulse. We show the capability of the technique to reconstruct both the amplitude and the phase of the field through the coherence of the nonlinear interaction down to a resolution of

Three-Dimensional Imaging of Drosophila melanogaster [PDF]
PLoS ONE, 2007 The major hindrance to imaging the intact adult Drosophila is that the dark exoskeleton makes it impossible to image through the cuticle. We have overcome this obstacle and describe a method whereby the internal organs of adult Drosophila can be imaged in 3D by bleaching and clearing the adult and then imaging using a technique called optical ...

Three-dimensional imaging modalities in endodontics [PDF]
Imaging Science in Dentistry, 2014 Recent research in endodontics has highlighted the need for three-dimensional imaging in the clinical arena as well as in research. Three-dimensional imaging using computed tomography (CT) has been used in endodontics over the past decade. Three types of CT scans have been studied in endodontics, namely cone-beam CT, spiral CT, and peripheral ...

Three-Dimensional Kaleidoscopic Imaging [PDF]
Imaging and Applied Optics Technical Papers, 2011 Planar mirror systems are capable of generating many virtual views, yet their practical use for multi-view imaging has been hindered by limiting configurations that enable view decomposition. In this work we lift those restrictions.

Three-dimensional imaging of dislocations [PDF]
Nature, 2013 arising from C.-C. Chen et al. , 74–77 (2013)10.1038/nature12009 At first sight, the achievement of determining atom positions in three dimensions appears spectacular1. Chen and colleagues1 apply a form of tomographic reconstruction to a tilt series of annular dark field (ADF) images of crystalline ...

FRET Imaging in Three-dimensional Hydrogels [PDF]
Journal of Visualized Experiments, 2016 Imaging of Förster resonance energy transfer (FRET) is a powerful tool for examining cell biology in real-time. Studies utilizing FRET commonly employ two-dimensional (2D) culture, which does not mimic the three-dimensional (3D) cellular microenvironment.

Three-dimensional imaging for large LArTPCs [PDF]
Journal of Instrumentation, 2017 High-performance event reconstruction is critical for current and future massive liquid argon time projection chambers (LArTPCs) to realize their full scientific potential. LArTPCs with readout using wire planes provide a limited number of 2D projections.
