Finite detector based projection model for high spatial resolution.
For finite detector and focal spot sizes, here we propose a projection model for high spatial resolution. First, for a given x-ray source point, a projection datum is modeled as an area integral over a narrow fan-beam connecting the detector elemental borders and the x-ray source point. Then, the final projection value is expressed as the integral obtained in the first step over the whole focal...
متن کاملMems-based Light Valves for Ultra-high Resolution Projection Displays
Ultra-high resolution projectors will improve the visual systems of military flight simulators dramatically. There are changes in aspect angle and aspect rate which fixed-wing fighter pilots can discriminate at long standoff distances, but which cannot be displayed with adequate resolution by the visual systems of contemporary flight simulators. At present the limit of display resolution is fix...
متن کاملHigh-resolution PET detector design: modelling components of intrinsic spatial resolution.
The development of dedicated small animal PET (positron emission tomography) scanners has led to significantly higher spatial resolution and comparable sensitivity to clinical scanners. However, it is not clear whether we are approaching the fundamental limit of spatial resolution. This work aims to understand what is currently limiting spatial resolution during data formation and collection an...
متن کاملMultishot for High Spatial Resolution
Conventional Cartesian non-diffusion pulse sequences acquire k-space in multiple excitations (a.k.a. shots). As the phase errors originating from motion during the diffusion preparation time are random in nature and large compared to the phase used to spatially encode the image, the use of multi-shot sequences with diffusion gradients is not straightforward, and in most cases severe image ghost...
متن کاملHigh-resolution image viewing on projection-based tiled display wall
In this paper we illustrate an application that displays high-resolution images on Multi-Projector Tiled High Resolution Display Wall. Our goal is to enable the users to view high-resolution image data, such as photos from satellites and microscopes. Panoramas can also be played circularly. Users can pan across the image, scale the image, and play panoramas interactively. Our prototype is imple...
