MRI scans are often under continues involuntary motion which weakens their reliability and diagnostic utility for examining the chest and abdomen. Acquisitions using traditional external sensors (e.g. respiratory belt) and self-gated techniques tend to be highly sensitive to patient position and setup, and on MR sequence parameters. Here, we demonstrate the use of accelerometer sensors for detecting respiratory signals. We show how the use of this simple sensor, with its relatively small dimensions, high sampling rate capability, and low cost, can produce motion corrected-images under free-breathing conditions.
