Shielded, Unshielded Electrode Leads

BIOPAC offers high-quality shielded and unshielded electrode leads in a variety of lengths. Clip leads (1 or 3 m; shielded or unshielded; RT) are available, as well as lead for EL120, NICO100C, and EBI100C. Used with BIOPAC transducers, AcqKnowledge software, the MP data analysis and acquisition hardware platforms, amplifiers and other system elements, these electrode leads are components of a complete data acquisition and analysis system.

For use in MRI, the following Lead Guidelines apply:

For MRI use, shorter leads are better, specifically, keeping lead lengths much shorter than the wavelength of the Larmor frequency (42.6 MHz/T) is critical. For a 3T machine, this is the speed of light divided by (42.6*3*1E6) or 2.34 meters. As field strengths increase, then lead lengths should continue to shorten. To record ECG, or any other biopotential signal in MRI, short leads such as LEAD108B (15 cm) and LEAD108C (30 cm) are recommended; do not use 2-meter or 1-meter leads for biopotential signals in MRI.

Additionally, BIOPAC recommends the following reference: Thoralf Niendorf, Lukas Winter and Tobias Frauenrath (2012).
