The MRI Center has deployed the Framewise Integrated Real-time MRI Monitoring (FIRMM) system.
FIRMM is an independent software system, installed on a Linux station. Receiving in parallel with the acquisition, the MRI data reconstructed in real time, the software evaluates, displays and saves the estimates of the subject’s movements (see diagram below).
Launch of FIRMM
FIRMM must be launched for each subject, according to the following procedure:
On the “Syngo MR” station (Windows):
- Pressing Ctrl + ESC opens the Windows system menu.
- Right-click on the shortcut “FIRMM_session_start” then choose “Run as administrator” from the context menu.
This activates the transfer of images to the “mri-server” computer (left against the wall) for the subject in question.
On the mri-server (Linux):
- Open a terminal by being connected under “firmmproc” (if the account used is “photon”, type “su firmmproc”, and then enter mriuser).
- Type the command ” FIRMM ” and validate. The FIRMM window opens after a few moments like a web page (figure below).
On the top right panel, the following buttons are present:
Click on “Start”: a pop-up window will appear asking you to choose the folder to select. If the expected subject is not proposed, wait a few moments: a scan must be transferred to the server for the subject in question to be visible by FIRMM).
Once the data has been received, FIRMM starts to evaluate the movements and displays them on the scrolling graph .
