Computational modelling of radiation transport can enhance the understanding of the
relative importance of individual processes involved in imaging systems. Modelling is a …

The response of a Silicon Photomultiplier (SiPM) to optical signals is affected by many
factors including photon-detection efficiency, recovery time, gain, optical crosstalk …

PET scanners based on monolithic pieces of scintillator can potentially produce superior
performance characteristics (high spatial resolution and detection sensitivity, for example) …

Emission imaging incorporates both the development of dedicated devices for data
acquisition as well as algorithms for recovering images from that data. Emission tomography …

We have previously reported on dMiCE, a method of resolving depth or interaction (DOI) in a
pair of discrete crystals by encoding light sharing properties as a function of depth in the …

Accurate gamma photon transport simulations of emission tomography systems are
important to optimise system geometries and for iterative image reconstruction. Monte Carlo …

Imaging systems are often modeled as continuous-to-discrete mappings that map the object
(ie a function of continuous variables such as space, time, energy, wavelength, etc) to a finite …

In many medical imaging modalities, as photons travel from the emission source to the
detector, they are scattered by the biological tissue. Often this scatter is viewed as a …

We examine a maximum-a-posteriori method for estimating the primary interaction position
of gamma rays with multiple interaction sites (hits) in a monolithic detector. In assessing the …

There have recently been a number of research groups investigating the use of high
resolution detector inserts within the imaging field of view to provide improved spatial …
