Med Phys
. 2020 Apr;
47(8):3321-3331.
PMID: 32329076
Purpose: 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...

Magn Reson Med
. 2020 Feb;
84(3):1661-1671.
PMID: 32077521
Purpose: Motion artifact limits the clinical translation of high-field MR. We present an optical prospective motion correction system for 7 Tesla MRI using a custom-built, within-coil camera to track an...

Spangler-Bickell M, Khalighi M, Hoo C, DiGiacomo P, MacLaren J, Aksoy M, et al.
IEEE Trans Radiat Plasma Med Sci
. 2019 Aug;
3(4):498-503.
PMID: 31396580
A significant challenge during high-resolution PET brain imaging on PET/MR scanners is patient head motion. This challenge is particularly significant for clinical patient populations who struggle to remain motionless in...

MacLaren J, Aksoy M, Ooi M, Zahneisen B, Bammer R
Magn Reson Med
. 2017 Jul;
79(4):1911-1921.
PMID: 28722314
Purpose: Optical prospective motion correction substantially reduces sensitivity to motion in neuroimaging of human subjects. However, a major barrier to clinical deployment has been the time-consuming cross-calibration between the camera...

Neuroimage
. 2017 Apr;
153:97-108.
PMID: 28359788
Introduction: Geometric distortions along the phase encode direction caused by off-resonant spins are still a major issue in EPI based functional and diffusion imaging. If the off-resonance map is known...

Magn Reson Imaging
. 2017 Feb;
39:44-52.
PMID: 28137627
Head motion is an unsolved problem in magnetic resonance imaging (MRI) studies of the brain. Real-time tracking using a camera has recently been proposed as a way to prevent head...

Neuroimage
. 2016 Jan;
129:117-132.
PMID: 26774615
Tractography is becoming an increasingly popular method to reconstruct white matter connections in vivo. The diffusion MRI data that tractography is based on requires a high angular resolution to resolve...

Magn Reson Med
. 2015 May;
74(2):571-7.
PMID: 25982242
Purpose: Physiological noise remains a major problem in MRI, particularly at higher imaging resolutions and field strengths. The aim of this work was to investigate the feasibility of using an...
