Electron multiplication charge-coupled devices (EMCCD) are widely used for photon
counting experiments and measurements of low intensity light sources, and are extensively …

Calibration of the gain and digital conversion factor of an EMCCD is necessary for accurate
photon counting. We present a new method to quickly calibrate multiple gain settings of an …

Detectors with continuous scintillator and matrix of photomultipliers attached are widely used
in modern particle physics and various medical tomographs. There are two common ways to …

In traditional lucky imaging (TLI), many consecutive images of the same scene are taken
with a high frame-rate camera, and all but the sharpest images are discarded before …

Image processing is fundamental to observational astronomy workflows. Astronomers
acquire imaging data, and process the imagery to extract useful information. This thesis …

Detection of x-rays and gamma rays with high spatial resolution can be achieved with
scintillators that are optically coupled to electron-multiplying charge-coupled devices …

High spatial resolution γ-imaging can be achieved with scintillator readout by low-noise, fast,
electron-multiplying charge-coupled devices (EMCCDs). Previously we have shown that …

Signal 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 …

Nondestructive characterization techniques such as gamma tomography represent powerful
tools for the analysis and quantification of physical defects and radionuclide concentrations …

In recent years, breast imaging using radiolabelled molecules has attracted significant
interest. Our group has proposed a multi-pinhole molecular breast tomosynthesis (MP-MBT) …
