Automatic Water Suppression Optimization

AWS optimization is a spectroscopy control variable that measures the impact of water suppression pulses and chooses a flip angle that minimizes the contribution of the water signal. Use AWS if your experience indicates that water is better suppressed with the Auto Prescan optimization process, the spectrum demonstrates too much water, or if you wish to use the optimization portion of the Auto Prescan process.

• Turning this CV off, eliminates the water suppression program in prescan by using predefined water suppression parameters reducing prescan time and eliminating the potential for AWS prescan failures.
• Prescan will take longer if you turn AWS Optimization on.
