Close-range feature-based head motion tracking for MRI and PET-MRI
Published 2018Optical motion tracking systems are effective in measuring head motion during MRI and PET scans. However, most systems rely on tracking attached markers which can slip or move relative to the head. In this study, we aimed ...Conference paper -
Characterization of the Intel RealSense D415 Stereo Depth Camera for Motion-Corrected CT Imaging
Published 2019A combination of non-contrast CT (NCCT) and CT Perfusion (CTP) imaging is the most common regime for evaluation of acute ischemic stroke patients. CTP-based image analysis is known to be compromised by patient head motion. ...Conference paper -
Non-rigid motion detection for motion tracking of the head
Published 2019Optical motion tracking systems are effective tools for measuring head motion during MRI and PET scans in order to correct for motion. Most systems rely on the attachment of fiducial markers which can slip or become decoupled ...Conference paper -
Open-field PET: Simultaneous brain functional imaging and behavioural response measurements in freely moving small animals
Published 2019A comprehensive understanding of how the brain responds to a changing environment requires techniques capable of recording functional outputs at the whole-brain level in response to external stimuli. Positron emission tomography ...Article -
Marker-free optical stereo motion tracking for in-bore MRI and PET-MRI application
