MRI-compatible accelerometers for tracking respiratory motion showed
reliable results in tracking motion when compared to conventional k-space
self-navigation. Its small dimensions and flexible high sampling rate offer
great potential for tracking of breathing signals.

setup with the accelerometer placed on top of the abdomen.
Figure 5. 3D view of data binned by k-space center (left
column), accelerometer (middle column) and Pilot-Tone RF transmitter (right
column). Data binned by the three methods were found to be in good agreement. Additionally,
data binned using the accelerometer signal showed fine tissue boundaries (green
arrow) and data binned using Pilot-Tone showed finer liver anatomical details
(yellow arrows).
