In-Class Questions

1. Say collect point every 16$\mu$s, and collect 256 points per line. How long to collect 1 line of data? Compare this to $T_{2,WM}$

2. Say that the magnitude of $G_{pe}$ must be fixed for some reason, how could phase encode stepping be completed in this case.

3. Given: $N_{x} \equiv N_{y} \equiv N_{z}=256$ and $T_{R}$ = 500ms, how long would a 3D experiment take to complete?? How long if $N_{z}$ = 128ms? How long if $N_{z}$ = 1, and $N_{x} \equiv N_{y}=256$ (2D case)?

4. Given $BW_{rf}$ = 2kHz, and $G_{max}$ = 10mT/m, what is $TH_{min}$? If you would like $n_{zc}$ to be equal to 3 how long must the pulse be???

5. Given $N_{x} \equiv N_{y} = 64$, and $T_{R}$ = 3s find $T_{T}$ for a 2D CSI experiment.
