Dynamic TG

Use Dynamic TG User CV with 2D Spin Echo and Fast Spin Echo single group. There are two Dynamic TG options:

• 1 = ON, allows auto prescan to compute the transmit gain value for each slice. The B1 map data is collected during prescan, TG estimates per slice are sent to the PSD, and the PSD adjusts the TG dynamically based on the slice location. The result is improved signal uniformity across all slices but a slightly longer prescan time.
• 0 = OFF, turns off Dynamic TG. The TG is calculated based only on the center slice and thus prescan time is slightly shorter.
