List Mode Reconstruction in X-Ray CT and SPECT Imaging
… radiation doses, and more recorded attributes. List mode data, which records all attributes in a list format, offers distinct advantages over binned data, including reduced storage requirements, improved data accuracy, and enhanced flexibility in reconstruction techniques. This thesis explores …

Objective Assessment Methods for List Mode Imaging System
… medical images that take the form of binned data. Here in this work, we focus on the list mode data, where instead of binning the incident locations, energies, or other formats of attributes, the attributes of each incident are recorded to form a list. This data format has the potential to …

Limits on subcritical reactivity determination using rossi-alpha and related methods
… performed using criticality eigenvalue (k-code) mode in MCNP R6.2. These simulations are used for comparisons on the linearity between α and ρ. Prompt neutron decay constant measurements in this work are performed using the Rossiα method. The measurements are taken using a 3He neutron detection …

Event-Driven Motion Compensation in Positron Emission Tomography: Development of a Clinically Applicable Method
… coincidence events, thus utilising the raw data of a PET system - the so-called `list-mode´ data. For routine acquisition of this raw data, methods have been developed which allow for the first time to acquire list-mode data from an ECAT Exact HR+ PET scanner within an acceptable time frame. …

Pulse Train Analysis Applied to the Re-Evaluation of Deadtime Correction Factors for Correlated Neutron Counting
… code MCNPXTM was used to generate a time-stamped list of neutron captures in 3He. Event times were processed in software to create neutron pulse trains akin to list mode data. The action of multiplicity shift register (MSR) electronics was modeled in software to analyse these pulse trains. Prior …
