Practical Tips for Recording Physiological Data in MRI
The MRI system incorporates a VERY strong magnetic field and both emits and records radio frequency (RF) energy. This has impacts on subject and experimenter safety and on data accuracy.
Signal Artifact Associated with MRI
By Alan Macy, BIOPAC Systems, Inc. When performing MRI and simultaneously recording time-series physiological data, there are two basic types of artifact associated with MRI processes. The first type of artifact is associated with the presence of the large constant...
Impedance Cardiography
By Alan Macy, BIOPAC Systems, Inc. ICG is a measurement method that is primarily used to determine aspects of Cardiac Output (CO). CO is the total amount of blood, pumped from both the left and right ventricles of the heart for each of its successive systolic...
Electrocardiogram Waveshape Pt. 2
In some situations, it can be helpful to craft a compromise between maximizing ECG signal bandwidth, preserving the essential ECG waveshape, reducing the impact of skeletal myo-electrical noise and removing mains interference.
