A Wireless Radio Frequency Triggered Acquisition Device (WRAD) for Self-Synchronised Measurements of the Rate of Change of the MRI Gradient Vector Field for Motion Tracking
TL;DR: The proposed wireless radio frequency triggered acquisition device enables users to probe the scanner gradient slew vector field with minimal hardware set-up and shows promise for the future developments in the prospective motion correction.
Journal ArticleDOI
Toward "plug and play" prospective motion correction for MRI by combining observations of the time varying gradient and static vector fields.
TL;DR: The efficacy of a Wireless Radio frequency triggered Acquisition Device (WRAD) is evaluated for high frequency (50 Hz) prospective motion correction in a 3‐dimensional spoiled gradient echo pulse sequence.
Journal ArticleDOI
A Method for Measuring Orientation Within a Magnetic Resonance Imaging Scanner Using Gravity and the Static Magnetic Field (VectOrient)
TL;DR: VectOrient is proposed for orientation measurement that is based on vector observations of gravity and the MRI scanner’s static magnetic field and is capable of quantifying subject respiration and heart rates.
Journal ArticleDOI
External Hardware and Sensors, for Improved MRI
Bruno Madore,Aaron T. Hess,Adam van Niekerk,Daniel Christopher Hoinkiss,Patrick Hucker,Maxim Zaitsev,Onur Afacan,Matthias Günther +7 more
TL;DR: A review of these ancillary devices, as currently available in clinical and research settings, is presented in this paper , where the authors use machine learning algorithms to combine diverse input signals toward coherent outputs, and make use of all such information toward improved MRI capabilities.
