Subject motion in MRI is a relevant problem in the daily clinical routine as well as in scientific
studies. Since the beginning of clinical use of MRI, many research groups have developed …

Physiological and physical motions of the subjects, eg, patients, are the primary sources of
image artifacts in magnetic resonance imaging (MRI), causing geometric distortion, blurring …

Magnetic resonance imaging allows for visualizing detailed pathological and morphological
changes of soft tissue. MR-conditional actuations have been widely investigated for …

This paper presents a novel actuation technology for robotically assisted MRI-guided
interventional procedures. In the proposed approach, the MRI scanner is used to deliver …

Purpose A novel prospective motion correction technique for brain MRI is presented that
uses miniature wireless radio‐frequency coils, or “wireless markers,” for position tracking …

Purpose Navigator‐based correction of rigid‐body motion reconciling high precision with
minimal acquisition, minimal calibration and simple, fast processing. Methods A short orbital …

Purpose To develop a method of tracking active NMR markers that requires no alterations of
common imaging sequences and can be used for prospective motion correction (PMC) in …

Map** aging-related brain structure and connectivity changes can be helpful for
assessing physiological brain age (PBA), which is distinct from chronological age (CA) …

Goal: A novel magnetic resonance (MR) compatible accelerometer for respiratory motion
sensing (MARMOT) is developed as a surrogate of the vendors' pneumatic belts. We aim to …

Active magnetic resonance (MR) tracking for gynecologic brachytherapy was made possible
by attaching the microradiofrequency coils to the brachytherapy applicator. The rectangular …
