Fisher Information in X-ray/Gamma-ray Imaging Instrumentation Design
… formation in a photon-counting x-ray/gamma-ray imaging detector is a complex process resulting in detector signals governed by multiple random effects. Recovering maximum possible information about event attributes of interest requires a systematic collection of calibration data and analysis …

Hybrid pixel-waveform semiconductor detectors: novel detector readout for semiconductor pet imaging of small animal neurodegenerative models
Developing nuclear detection instrumentation for biomedically selected tasks uniquely produces a dualistic intellectual challenge: the engineering of the instrument cannot occur without mastery knowledge of its governing principles while a lack of clear understanding of the application provides an …

Ray-based Physical Optics for the Design of Astronomical Observatories
… pupil-plane and image-plane masks. When imaging Earth-like exoplanets at small angular separations, coronagraphs are limited by telescope stability and polarization aberrations. The state of the art handles the diffraction model, ray aberration model, and polarization model separately …

Development and Application of Computational Tools for the Study and Optimization of Variable Resolution X-ray (VRX) Computed Tomography Scanners
… analysis and evaluation of some aspects of VRX imaging. This included a comparison of the performance of different targeting VRX geometries in terms of spatial and contrast resolution, and a study of the effect of the VRX angle on the severity of common artifacts in single-arm images.</p>
