Confirm Frequency Adjustment - Numaris X

Confirm Frequency Adjustments Numaris X Job Aid Confirm Frequency Adjustments – Numaris X Confirm Frequency is a parameter used to perform semi-automatic adjustments for Fat, Water, or Silicone Suppression. 1. Open Pulse Sequence a. Select System > Adjustments 2. Select Confirm Frequency > select an Option a. Options – defines when Confirm Frequency Adjustment box appears i. Never – Confirm Frequency Adjustment box never appears ii. Always – Confirm Frequency Adjustment box appears before every meas- urement iii. When Changed – Confirm Frequency Adjustment box only appears if reso- nance frequency was changed due to an inline adjustment. 1. e.g., used for most protocols with fat, water, or silicone suppression Routine Contrast Resolution Geometry System Physio "Inline Sequence Miscellaneous Adjust Voluma TXRX Adjustment Strategy Standard Adjustment, Taleranco Auto (Maxi 80 Shim: Standard Adjust with Body Col.I B1 Shim: TrueForm Confirm Frequency lever Assume Salicone Always When Changed Manuel Adjustments 3.
