ADAPTIVE RIGHT LEG DRIVE FOR BIO-POTENTIAL MEASUREMENTS IN THE MRI ENVIRONMENT

The present disclosure describes various systems and methods of adaptively taking bio-potential measurements of within a changing environments. Specifically, the systems and methods are directed to adaptive control of a bio-potential measurement device thereby enabling the use of the bio-potential measurement device within environments having different noise sources, such as environments with and without a device generating strong magnetic fields. Through adaptive measures, the systems and methods of the present disclosure improve the usage of a right leg drive by adaptively changing the nature of the drive itself according to its present environment (e.g., MR vs. non-MR environment). In addition to improvements in common mode rejection (CMR), the systems and methods of the present disclosure can reduce the required analog front-end dynamic range.
