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.
Offering the industry’s only system that delivers a comprehensive, 24-hour data logging solution in an easy-to-use, easy-to-wear package, the BioNomadix Logger® truly delivers “physiology anywhere.” The BioNomadix Logger is the perfect tool for applications that demand greater degrees of subject freedom and complex experimental design. BioNomadix Loggers wirelessly record physiological data as subjects freely and naturally […]
Studying Cognitive Activity with fNIR! The age-old game of chess is known as a thinking man’s game, where foresight, critical thinking, and strategy are required to become a good chess player, and the terms “genius” or “brilliance” are bestowed upon the chess masters of the world. As such, chess is an excellent cognitive tool to […]
