This application note lays out some generally recommended methods for recording data from subjects in the MRI or fMRI. BIOPAC Systems, Inc. (BIOPAC) designs systems that can be used to record both biopotential data (such as ECG, EEG and EMG) and transducer data (such as blood pressure, air flow, hand clench strength, finger motion and temperature).
In most MRI configurations, there is a “dual-room” setup. In these cases, there is a “Chamber” room and a “Control” room. The chamber room houses the actual MRI machine and the control room is where the MRI operator sits to manage the MRI scanning sequences.
BIOPAC MRI-related recording equipment is typically setup with the recording equipment data acquisition system and associated amplifiers in the control room (well-away from MRI). Signals are directed, via a filtered cabling system, from the subject—lying in the MRI—to the recording equipment. The cabling system, though conductive, does not contain ferromagnetic materials. The electrodes or transducers attached to the subject in the MRI are plugged into the receiving end of the cabling system.
The fEMG Electromyography Smart Amplifier is designed specifically for recording facial EMG signals and electrical activity from other small muscle groups. Use with AcqKnowledge™ software to analyze facial expressions and startle paradigms. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level […]
Recent psychophysiological studies feature BIOPAC’s MP Research series of Data Recorders and AcqKnowledge software. Creating Adaptive Assistants for helicopter crews based on Real-time Physiological Data In the Mercedes S-Class, biometric tools track a driver’s eyes, heart rate, and other physiological data, with one goal in mind: Making sure drivers are alert and safe on the […]
