Brief Summary:
A novel magnetic resonance (MR) compatible accelerometer for respiratory motion sensing (MARMOT) has been developed as a surrogate of the vendors' pneumatic belts. The aim is to model and correct respiratory motion for free-breathing thoracic-abdominal MR imaging and to simplify patient installation.
Detailed Description:
Respiratory motion is a serious problem in the acquisition of high-quality thoracic/abdominal magnetic resonance (MR) images. Various methods have been proposed to compensate the motion-induced artefacts, including breathholding, respiratory gating and model-driven motion correction.
Breath-holding is the simplest among the three. However this conventional clinical method induces various problem, including inefficient use of scanners, inconsistent organ position between each breath-hold, imaging an altered physiological status and patient inconvenience especially for those who suffer from respiration difficulties. Free-breathing MR acquisition has therefore become of great clinical interest recently.
The investigators intend to examine the efficacy of the MARMOT sensors for:
* modelling and predicting the respiratory motions in abdominal scans,
* correcting for the respiratory motion in a cardiac cine scan, via a reconstruction-based method.
