INFORMATION TRANSFER EFFICIENCY OF X-RAY IMAGE INTENSIFIER-BASED IMAGING SYSTEMS.
… and verified experimentally with an x-ray image intensifier (XRII)-based imaging system. In such a system, the DQE at low frequency range is primarily determined by the x-ray detection and scintillation processes at the CsI layer of the XRII. The effects of x-ray photon energy and sensor …

Development of a Full-Field Time-of-Flight Range Imaging System
A full-field, time-of-flight, image ranging system or 3D camera has been developed from a proof-of-principle to a working prototype stage, capable of determining the intensity and range for every pixel in a scene. The system can be adapted to the requirements of various applications, producing high …

The direct measurement of system Modulation Transfer Function (MTF) for an AN/AVS-6 Aviator's Night Vision Imaging System (ANVIS)
… imaging systems such as the lenses and the image intensifier tube. The current method for calculating the system MTF is to combine the MTFs of all the components of the imaging system. Little research has been performed to directly measure the MTF of the entire system. This thesis describes …

Development of x-ray luminescence detection system and characterization of x-ray irradiated quantum dots for image-guided x-ray photodynamic therapy
… coupled device (EMCCD), a demagnifying (DM) image intensifier, and on optical lens to monitor XL signal emitted from the QDs. We used core-shell QDs and doped QDs to characterize their XL properties and absorption of X-ray photons. Along with the characterization of XL, the work eventually …

A CMOS-compatible compact display
… demand displays with high resolution and high image quality that are increasingly compact and energy-efficient. Microdisplays consisting of a silicon CMOS backplane integrated with light generating or modifying devices, are being developed for direct-view and projection applications. A …

Microcomputer control of a three-dimensional stereoflouroscope
… will control two grid-pulsed x-ray sources, an image intensifier, a solid-state video camera, a video monitor and the PLZT goggles to provide a stereoscopic image. Dose reduction should be obtained through the use of the computer as the controlling mechanism. Two storage tubes will be …

Digital frequency domain fluorometry and the study of Hoechst 33258 DYE-DNA interactions
… and the development of a method to modulate an image intensifier made it possible to incorporate linear and matrix detectors in frequency domain fluorometry. The extension of time-resolved fluorescence measurements to linear arrays has made it possible to follow the time evolution of the …

Cone Beam Computed Tomography - radiation dose and image quality assessments
… volume size (FOV), radiation quality, image capturing and reconstruction, image resolution and radiation dose. When new technology is introduced one must make sure that diagnostic accuracy is better or at least as good as the one it can be expected to replace. The CBCT brand tested was …

New photonic imaging systems for biomedical applications
… Current PLIM platforms have limitations in image acquisition speed, sensitivity, penetration depth, accuracy, and general usability. TCSPC with raster scanning technique is frequently used in PLIM, but it is slow as it requires long pixel dwell times to measure long-lived phosphorescence. …
