Characterization of the Intel RealSense D415 Stereo Depth Camera for Motion-Corrected CT Imaging
Dashtbani Moghari, Mahdieh; Noonan, Philip; Henry, David; Fulton, Roger R.; Young, Noel; Kyme, AndrePublished 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
Henry, David; Fulton, Roger R.; Maclaren, Julian; Aksoy, Murat; Bammer, Roland; Kyme, AndrePublished 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 -
Markerless motion estimation for motion-compensated clinical brain imaging
Kyme, Andre; Se, Stephen; Meikle, Steven R.; Fulton, Roger R.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
Henry, David; Fulton, Roger R.; Maclaren, Julian; Aksoy, Murat; Bammer, Roland; Kyme, AndrePublished 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
Kyme, Andre; Angelis, Georgios I.; Eisenhuth, John; Fulton, Roger R.; Zhou, Victor; Hart, Genevra; Popovic, Kata; Akhtar, Mahmood; Ryder, William J.; Clemens, Kelly J.; Balleine, Bernard W.; Parmar, Arvind; Pascali, Giancarlo; Perkins, Gary; Meikle, Steven R.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
Henry, David; Yao, Yidi; Fulton, Roger R.; Kyme, AndrePublished 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
