a) In both the slice select and read directions, it is often desirable to keep the gradients used prior to sampling the data as short as possible to reduce the effects of motion. Neglecting the phase encoding time, how can this be accomplished while satisfying the conditions on the area of the slice select rephasing and the read dephasing gradients if Gss, GR, Trf, and Ts are fixed for other reasons? Remember that you are constrained by a maximum possible gradient strength in each direction. b) Draw a sequence diagram showing the shortest possible echo time, assuming that the slice select and read gradients used are 0.1Gmar, where Gmar is the maximum available gradient strength for either gradient. Label the magnitudes and duration of all gradients used in terms of Trf, Ts, and Gmar. Assume tramp = 0. a) In both the slice select and read directions, it is often desirable to keep the gradients used prior to sampling the data as short as possible to reduce the effects of motion.
