This image shows an ACR phantom.
Select one:
True
False - CORRECT ANSWER✅✅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)
