MRI “triggering” operates to drive a digital channel of data. This data is collected along with other physiological signals. There are two ways to trigger the MRI.
There is no software processing involved and no associated delays. The digital trigger product pages contain more setup information to send a trigger based on the following physiological signals: ECG R-wave, blood pressure, respiration, and/or integrated EMG.
Note that when setting up the trigger in AcqKnowledge 5 or above, analog channels must be set first in order to see the channel listing (analog) in the Trigger drop down.
Delays could be introduced because performance will depend on the specifications of the computer you are using as well as the current processing load on that computer.
See application note AS191 for details.

View AllThe Mobita 32-Channel EEG recording system was used in research examining if physiological data can be used to predict truly random events that correspond to perceptual stimuli. Baumgart, et al. from the University of California Santa Barbara utilized a quantum random number generator (qRNG) to choose from three randomized conditions: light, sound, and no stimulus. […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies in monitoring respiration and cardiovascular activity. The coupling between peripheral microcirculation and slow breathing: The purpose of this study was to investigate the coupling of breathing movements and microcirculatory blood […]
