Tips For Rebooting the Scanner When Problem Arise

If problems arise during your scanner session, it may be necessary for you to reboot the scanner. There are three distinctly different ways to reboot the scanner. How to choose the correct way is sometimes not obvious, but the correct choice can save you a lot of time.

Rebooting Everything

If you encounter a console crash or other unrecoverable error in the software that runs on the console, your only alternative may be to do a complete shutdown and reboot of the entire system. Crashes like those you encounter on your personal PC or error messages indicating that the reconstuction computer has crashed require this type of reboot.

In terms of time required, this is the most expensive way to reboot the system, since the operating system and the Syngo software must be completely reloaded.

• Move the bed completely out of the scanner. You're going to have to do it before you can resume scanning, so you might as well do it now.
• From the "System" menu, choose "End"
• Wait until the console computer gives a message indicating that it is safe to turn off the computer (several other messages will typically be displayed before this one)
• Press the blue power off button on the wall-mounted control unit
• Wait 10 seconds
• Press the blue power on button on the wall-mounted control unit
• Wait until the system has rebooted
• Re-register the subject
• Re-landmark the subject
• Resume scanning

Rebooting the Scanner Hardware and Software

If you are getting an error indicating a problem with the scanner (i.e., not with the console computer), the problem should be resolvable by rebooting just the scanner. An example of such an error would be "Watchdog Error ... blah blah blah ... Reboot Scanner"

• Move the bed completely out of the scanner. You're going to have to do it before you can resume scanning, so you might as well do it now.
• From the "System" menu, choose "Control"
• In the System Manager window, choose the tab that says "MR Scanner"
• Even though the error message said reboot, don't push the "Reboot" button--this will reboot the software (see next rebooting method), but will not reboot the scanner hardware.
• Press the "Stand By" button in the System Manager window
• Wait 10 seconds
• Press the "System On" button in the System Manager window
• Once all the items in the System Manager Windo have green checkmarks, you are ready to put the bed back in and resume scanning
• If the PALI and STIMO items turn red and never go green, you probably failed to bring the bed out of the scanner. Do so now so that the scanner can complete its reboot
• Re-landmark the subject
• Resume scanning

Rebooting the Scanner Software Only

This is the fastest reboot, but solves only problems that involve the scanner software.

• You might be able to get away without removing the bed from the scanner
• From the "System" menu, choose "Control"
• In the System Manager window, choose the tab that says "MR Scanner"
• Press the button that says "Reboot"
• Once all the items in the System Manager Window have green checkmarks, you are ready to put the bed back in and resume scanning
• If the PALI and STIMO items turn red and never go green, you'll have to take the bed out of the scanner before you can continue.
