Echo Tuning

Echo Tuning compensates for phase errors that accumulate within the echo train. Echo tuning is performed for each slice location at the start of each acquisition. Enter 1 to prompt the system to display a representation of the echoes from which proper alignment can be assessed. The reconstructed images are not displayed when this variable set to 1.

• When acquiring an FGRE-ET MP (multi-phase) acquisition, run a trial acquisition to evaluate the success of the echo tuning alignment process. If there is an unacceptable amount of image blurring as shown above, adjust the Echo Delay and repeat the echo alignment procedure.
• You can repeat the process as often as necessary to get the echoes in alignment.
