SUMMARY
Due to the static magnetic_field inside the MRI scanner accompanied by an inherent radiofrequency (RF) and electromagnetic (EM) disturbance, a special realization of sensors must be used for PPG signal pickup. The present work was practically motivated by seeking suitable and universal parameter settings for PPG signal real-time recording in different working mode conditions including proper function in a weak magnetic_field environment. First-step measurements inside the scanning area of the working MRI device with low magnetic_field verify practical functionality of both PPG sensors and their potential usability in further measurements. It means . . .
