Abstract Recent years have seen the rapid growth of new approaches to optical imaging, with an emphasis on extracting three-dimensional (3D) information from what is normally a two-dimensional (2D) image capture. Perhaps most importantly, rise computational imaging enables both physical layouts components and algorithms be implemented. This paper concerns convergence two advances: development t...

We demonstrate high-speed terahertz (THz) reflection three-dimensional (3D) imaging based on electronically controlled optical sampling (ECOPS). ECOPS enables scanning of an axial range of 9 mm in free space at 1 kHz. It takes 80 s to scan a transverse range of 100 mm × 100 mm along a zigzag trajectory that consists of 200 lines using translation stages. To show applicability of the imaging sys...

A new system for 3D clinical imaging was recently developed that takes a 2D image and converts it into a 3D image. This is incredibly useful in the medical imaging world as it is cost effective, easy to use, and non-invasive. We seek to improve the algorithm and software coding used to create 3D images so that it is compatible with other cameras and provides a better image. There are three main...

3D imaging system was developed utilizing a combination of sparse 2D arrays, the synthetic aperture focusing technique, and coded excitation of a solution for high-speed 3D ultrasound imaging, since it could formulate multiple transmitting beams as well as receiving beams with a minimum number of transmissions. A 40 × 40 array of PZT elements was fabricated with a conventional dice-and-fill pro...

Although the principle of using x-rays for diagnostic imaging has been known for a long time, there is still a lot of research and improvements going on in the field. One recent addition to the neuro-vascular imaging system—used for visualizing blood vessels in the brain and guidance of interventions—is 3D rotational angiography (3D-RA). Using 3D-RA, it is possible to view the vessel tree in 3D...

We report a new implementation of three-dimensional (3D) momentum imaging for electrons, employing two-dimensional (2D) detector and silicon photomultiplier tube (siPMT). To achieve the necessary time resolution 3D electron imaging, poly(p-phenylene)-dye-based fast scintillator (Exalite 404) was used in instead conventional phosphors. The system demonstrated an time-of-flight comparable with th...

PURPOSE To design a simple and reproducible method with minimum uncertainty for evaluating the stereotactic accuracy of Computed Tomography imaging and Magnetic Reso-nance Imaging and to compare the results. METHODS 3D phantom has been designed with 1 mm diameter targets in eight sectors for stereotactic MR imaging and CT imaging. The phantom was connected to Leksell stereotactic frame and th...

Anatomic study related to the anterior cruciate ligament (ACL) reconstruction surgery has been developed in accordance with the progress of imaging technology. Advances in imaging techniques, especially the move from two-dimensional (2D) to three-dimensional (3D) image analysis, substantially contribute to anatomic understanding and its application to advanced ACL reconstruction surgery. This p...

An efficient hardware architecture for the acceleration of an integrated 3D reconstruction method is presented, targeting demanding dynamic Integral Imaging applications. It exploits parallel processing and features minimized memory operations by implementing an extended-access memory scheme. Its reduced data throughput, thanks to optimized data utilization, makes it suitable for single FPGA de...

Laser scanning systems for two-photon microscopy and fabrication have been proven to be excellent in depth-resolving capability for years. However, their applications have been limited to laboratory use due to their intrinsic slow nature. The recently introduced temporal focusing concept enables wide-field optical sectioning and thus has potential in both high-speed 3D imaging and 3D mass-produ...
