fMRI Visual System

One of the challenges in fMRI is to synchronize stimulus presentation with MR acquisition. Accuracy of timing and timing information is critical to the validity of results.


During image acquisition the MR scanner produces trigger information. With a flexible and user-friendly menu system, the SyncBox allows the user to select how the trigger pulse from the MR scanner is transferred to the software presenting the stimuli.


Compatible with the leading software packages, the SyncBox provides a user-friendly solution for accurate control over stimulus presentation and easily accessible timing information for data analysis.


The SyncBox can simulate the trigger signals produced by the scanner during an MR sequence. This enables the user to develop and test the entire experimental paradigm in the office, minimizing the need for costly scanner time. The SyncBox also features a recording function, which allows the user to record triggers from the MR sequence for playback in the office.


Using the SyncBox for research
Research projects will benefit from the added accuracy due to automatic control over the experimental protocol. The SyncBox also interfaces with a variety of external devices, allowing for synchronization of signals from different hardware sources and accurate logging of timestamps.


Using the SyncBox for clinical routine applications
The acceptance of fMRI as a clinical diagnostic procedure hinges on the availability of standardized fMRI paradigms and easy-to-use tools. The clinical use of fMRI requires simple, automated procedures which can handle stimulus generation, image acquisition and data analysis. In combination with a basic set of fMRI paradigms, the SyncBox enables a single MR technologist to conduct an fMRI session as a routine clinical procedure.

The SyncBox is developed in collaboration with:
