################################################# FIRMM Usage with High Dynamic Range (HDR) Enabled ################################################# Initiating the FIRMM Real-Time Motion Plotting Software with HDR Enabled ======================================================================== Stop the Default FIRMM Connection --------------------------------- .. Attention:: BEFORE REGISTERING YOUR PATIENT: Stop the current FIRMM processes (by default, the FIRMM software will be running when you arrive at the scanner). * Hit: “Cntrl-Esc” to open the standard Windows menu * Near the top of the menu, you will see several FIRMM-related options * Right-click on “FIRMM stop always-send” * In the sub-menu for this option, click “Open” * DO NOT SELECT “Run as administrator” .. image:: images/firmm_hdr/firmm_hdr_1.png :width: 800 * A terminal will open and the FIRMM system will start shutting down the connection to the scanner * Allow the terminal window to complete the process before closing it .. image:: images/firmm_hdr/firmm_hdr_2_new.png :width: 800 Reboot the FIRMM Tablet ----------------------- .. image:: images/firmm_hdr/firmm_hdr_3.png :width: 800 .. image:: images/firmm_hdr/firmm_hdr_3b.png :width: 800 .. image:: images/firmm_hdr/firmm_hdr_3d.png :width: 800 Begin Your Imaging Session (with FIRMM off) ------------------------------------------- * At this point, you can start your session and go through all the typical procedures used by your project. * When the time comes to turn on the High Dynamic Range (HDR) option, use the standard method outlined here: * https://ucsd-center-for-functional-mri-cfmri-prisma-external.readthedocs-hosted.com/en/latest/hdr.html#manipulating-the-hdr-flag .. Attention:: If your protocol uses Auto-Align to position your Rx, do not turn on the HDR flag until AFTER the Auto-Align routine is complete (E.g., Localizer, AAHScout, Localizer_aligned). * After the HDR flag has been switched ON, you can turn re-establish the FIRMM motion tracking software connection using the info below. * After the FIRMM tablet reboots, the display will look like the image below, indicating that FIRMM is “DISCONNECTED” .. image:: images/firmm_hdr/firmm_hdr_tab1.png :width: 800 Re-Establishing a Connection to the FIRMM Software -------------------------------------------------- * Hit: “Cntrl-Esc” to open the standard Windows menu * Near the top of the menu, you will see several FIRMM-related options * Right-click on “FIRMM start ONE PATIENT” * In the sub-menu for this option, click “Open” * DO NOT SELECT “Run as administrator” .. image:: images/firmm_hdr/firmm_restab.png :width: 600 * A terminal window will open and the re-connection to the FIRMM tablet will begin. * Wait for the processes to complete. The window will close automatically. * After you see “CONNECTED”, you are ready to resume scanning. .. image:: images/firmm_hdr/firmm_hdr_onepatient.png :width: 600 * The FIRMM tablet should look like the image below, indicating that FIRMM is “CONNECTED”. .. image:: images/firmm_hdr/firmm_hdr_onepatient_2.png :width: 600 Resetting the FIRMM Threshold Parameter --------------------------------------- * After a reboot, the system will default to 0.2 mm for the motion threshold. * We generally set this to 0.4 mm, but your project can decide how strict your threshold should be for the display. .. image:: images/firmm_hdr/firmm_hdr_threshold.png :width: 800 Monitoring Motion During Your fMRI, DTI, and T1/T2 Acquisitions --------------------------------------------------------------- * During your session, you should automatically see the motion plots for your fMRI, DTI, and T1/T2 acquisitions. * Note: Only T1 & T2 acquisitions including the navigation setter scan will work with FIRMM. POST SCAN REQUIREMENTS ====================== .. Attention:: At the end of your MRI booking, you will need to return the FIRMM tablet to the default configuration. Stop the "One Patient" FIRMM Connection --------------------------------------- * Hit: “Cntrl-Esc” to open the standard Windows menu * Near the top of the menu, you will see several FIRMM-related options * Right-click on “FIRMM stop one patient” * In the sub-menu for this option, click “Open” * DO NOT SELECT “Run as administrator” .. image:: images/firmm_hdr/firmm_hdr_stop_onepatient.png :width: 800 Reboot the FIRMM Tablet After Your MRI Session ---------------------------------------------- .. image:: images/firmm_hdr/firmm_hdr_3.png :width: 800 .. image:: images/firmm_hdr/firmm_hdr_3b.png :width: 800 .. image:: images/firmm_hdr/firmm_hdr_3d.png :width: 600 Restore the Default FIRMM Connection for the Next Group ------------------------------------------------------- * Hit: “Cntrl-Esc” to open the standard Windows menu * Near the top of the menu, you will see several FIRMM-related options * Right-click on “FIRMM start always-send” * In the sub-menu for this option, click “Open” * DO NOT SELECT “Run as administrator” .. image:: images/firmm_hdr/firmm_start_always_send.png :width: 600 * A terminal window will appear with a countdown. * Leave the window open and allow it to complete the process. .. image:: images/firmm_hdr/firmm_hdr_connected_post_reboot_start.png :width: 600
