3-Plane Localizer considerations

Consider this information when modifying the scan parameters for a 3-Plane Localizer.

• Some scan parameters are automatically selected.
• If the center of the FOV, for any of the prescribed slices, falls outside of the scan range of the selected coil, a message is posted. Change the Center of FOV location or decrease the number of slices per plane.
• Normal level for dB/dt is always used to acquire a FGRE, FGRE-IR Prep and FIESTA localizer scan, regardless of the option button selected from the SAR and dB/dt screen. A SSFSE localizer scan uses the selected dB/dt option button.
• The SAR level is based on the option button selected on the SAR and dB/dt screen.
• If more than one slice is prescribed, then the FOV center coordinates represent the center slice, not the starting slice.
• A unique number of slices can be prescribed for each scan plane. For example, 3 coronal, 3 sagittal, and 15 axial images can be prescribed.
• A unique spacing value can be prescribed for each scan plane.
• As the number of slices increases, the scan time increases.
