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. ...Open AccessConference paper -
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 ...Open AccessConference paper -
Deep learning-based motion estimation for uninterrupted tracking of awake rodents in PET
Published 2018The ability to image the brain of awake rodents using motion-compensated positron emission tomography (PET) presents many exciting possibilities for exploring the links between brain function and behavior. A key requirement ...Open AccessConference paper -
Feasibility of marker-free motion tracking for motion-corrected MRI and PET-MRI
Published 2016Prospective motion correction is a very promising compensation approach for magnetic resonance imaging (MRI) studies impacted by motion. It has the advantage over retrospective methods of being applicable to any pulse ...Open AccessConference paper -
Implantation and long-term assessment of the stability and biocompatibility of a novel 98 channel suprachoroidal visual prosthesis in sheep
Published 2021Severe visual impairment can result from retinal degenerative diseases such as retinitis pigmentosa, which lead to photoreceptor cell death. These pathologies result in extensive neural and glial remodelling, with survival ...Article -
Marker-free optical stereo motion tracking for in-bore MRI and PET-MRI application
Published 2020Purpose: Prospective motion correction is arguably the “silver bullet” solution for magnetic resonance imaging (MRI) studies impacted by motion, applicable to almost any pulse sequence and immune from the spin history ...Open AccessArticle -
Markerless motion estimation for motion-compensated clinical brain imaging
Published 2018Motion-compensated brain imaging can dramatically reduce the artifacts and quantitative degradation associated with voluntary and involuntary subject head motion during positron emission tomography (PET), single photon ...Open AccessArticle -
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 ...Open AccessConference 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 ...Open AccessArticle -
An optimized feature detector for markerless motion tracking in motion-compensated neuroimaging
Published 2017Head movements during PET and MRI scans can have a detrimental effect on image quality and quantitative measurements. For both modalities, motion correction methods exist that rely on accurate characterization of head ...Open AccessConference paper -
Silhouette-based markerless motion estimation of awake rodents in PET
Published 2017The ability to image the brain of a freely moving rodent using motion-compensated PET presents many exciting possibilities for exploring the links between brain function and behavior. Markerless optical approaches for pose ...Open AccessConference paper
