A deep neural network for positioning and inter-crystal scatter identification in multiplexed PET detectors

Autor: Enriquez-Mier-y-Teran, Francisco E, Zhou, Luping, Meikle, Steven R, Kyme, Andre Z

Objective: Conventional event positioning algorithms in light-sharing PET detectors are often limited by edge effects and the impact of inter-crystal scattering (ICS). This study explores the feasibility of deep neural network (DNN) techniques for mo

Spatio-Temporal Correlation of Epileptic Seizures with The Electrocardiography Brain Perfusion Index

Autor: van Bohemen, Samuel J, Nardo, Joe O, Rogers, Jeffrey M, Stephens, Eleanor, Wong, Chong H, Bleasel, Andrew F, Kyme, Andre Z

The Electrocardiography Brain Perfusion index (EBPi) is a novel electrocardiography (ECG)-based metric that may function as a proxy for cerebral blood flow (CBF). We investigated the spatio-temporal correlation between EBPi and epileptic seizure even

Safety, feasibility, and acceptability of a novel device to monitor ischaemic stroke patients

Autor: van Bohemen, Samuel J, Rogers, Jeffrey M, Alavanja, Aleksandra, Evans, Andrew, Young, Noel, Boughton, Philip C, Valderrama, Joaquin, Kyme, Andre Z

This study assessed the safety, feasibility, and acceptability of a novel device to monitor ischaemic stroke patients. The device captured electroencephalography (EEG) and electrocardiography (ECG) data to compute an ECG-based metric termed the Elect

Characterisation of the Intel RealSense D415 Stereo Depth Camera for Motion-Corrected CT Perfusion Imaging

Autor: Moghari, Mahdieh Dashtbani, Noonan, Philip, Henry, David, Fulton, Roger R, Young, Noel, Moore, Krystal, Evanns, Andrew, Kyme, Andre

Even for short protocols (<1 min), head movement can compromise accurate haemodynamic modelling of cerebral CT perfusion (CTP) imaging in acute stroke. Frame-to-frame registration is the most common form of retrospective correction but neglects the f

Virtual Cylindrical PET for Efficient DOI Image Reconstruction with Sub-millimetre Resolution

Autor: Enríquez-Mier-y-Terán, Francisco E, Kyme, Andre Z, Angelis, Georgios, Meikle, Steven R

Objective: Image reconstruction in high resolution PET scanners with depth of interaction (DOI) capability is computationally challenging due to the high sampling in detector and image space. This study evaluates the use of a virtual cylinder to redu

Publikováno v: Communications Biology, Vol 7, Iss 1, Pp 1-15 (2024)

Abstract The World Health Organization has designated Pseudomonas aeruginosa as a critical pathogen for the development of new antimicrobials. Bacterial viruses, or bacteriophages, have been used in various clinical settings, commonly called phage th
