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.
High-performance mobile fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). These top of the line systems provide cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. Mobile subjects are comfortable and can respond naturally in real-world situations to take a test or perform mobile […]
