True
False Ans: False
Center frequency must be measured and recorded ______.
(the center frequency is the frequency in the middle of the transmit BW -
range of frequencies - of the RF pulse, and it is used to select the exact
position of the slice together with the SEG. The tBW around the center
frequency will determine the slice thickness together with the SEG)
