223 – Physiological Measurement in Magnetic Resonance Imaging Systems

Generally considered, if the transducer is able to be used in the MRI (see BIOPAC MRI Use declarations), the transducer signal can be relatively easily recorded during an MRI scan (an MRI Overview begins on page 3). Transducer signals are typically high level and slow moving. These two features allow the transducer signal to be easily filtered to remove MRI artifact to produce the clean signal.
