Fully Automatic Three-Dimensional Ultrasound Imaging Based on Conventional B-Scan

open access: yesIEEE Transactions on Biomedical Circuits and Systems, 2018
Robotic ultrasound systems have turned into clinical use over the past few decades, increasing precision and quality of medical operations. In this paper, we propose a fully automatic scanning system for three-dimensional (3-D) ultrasound imaging.

Three-Dimensional Image. Representation of 3 D Spacial Information by Rays and Its Application.

open access: yesThe Journal of the Institute of Television Engineers of Japan, 1996
In this paper, we propose a new framework of representing 3-D spacial information by using 'Rays'. We show that this data format includes all the information of the scene viewed from any direction, so that, one view image from an arbitrary viewpoint can be obtained by sampling ray data.

Three-dimensional imaging using computer-generated holograms synthesized from 3-D Fourier spectra [PDF]

open access: yesJournal of Physics: Conference Series, 2008
Computer-generated holograms(CGHs) synthesized from projection images of real existing objects are considered. A series of projection images are recorded both vertically and horizontally with an incoherent light source and a color CCD. According to the principles of computer tomography(CT), the 3-D Fourier spectrum is calculated from several projection

Measuring three-dimensional dynamics of platelet activation using 3-D quantitative phase imaging [PDF]

open access: yes, 2019
Abstract Platelets, or thrombocytes, are anucleated tiny blood cells with an indispensable contribution to the hemostatic properties of whole blood, detecting injured sites at the surface of blood vessels and forming blood clots. Here, we quantitatively and non-invasively investigated the morphological and biochemical alterations of ...

Automatic Regularization of TomoSAR Point Clouds for Buildings Using Neural Networks

open access: yesSensors, 2019
Tomographic SAR (TomoSAR) is a remote sensing technique that extends the conventional two-dimensional (2-D) synthetic aperture radar (SAR) imaging principle to three-dimensional (3-D) imaging.

Three-dimensional Multiple-Input Multiple-Output Radar Imaging Method Based on Integration of Multi-snapshot Images

open access: yesLeida xuebao, 2020
To improve the cross-range resolution of three-dimensional (3-D) images obtained along the direction of movement by Multiple-Input Mmultiple-Output (MIMO) radar, a novel MIMO-ISAR 3-D imaging method that combines multi-snapshot images is proposed.

Three-Dimensional Imaging of Displaced Intra-articular Calcaneal Fractures Correlates With the Perioperative Diagnosis

open access: yesFoot & Ankle Orthopaedics, 2021
Background: Intra-articular calcaneal fractures are complex injuries, and CT imaging has become the standard imaging in the preoperative assessment. Most classifications of these fractures are CT-based but have been associated with limited interobserver ...
