Final Answer:
The correct match-up would be:
b) i. gx - b, ii. gy - c, iii. gz - a
i. gx (gradient along x) is typically applied during the RF transmission.
ii. gy (gradient along y) is usually applied between the RF and the readout.
iii. gz (gradient along z) is applied during the echo.
Step-by-step explanation:
These match-ups correspond to the gradients used in MRI (Magnetic Resonance Imaging) during different stages of the imaging process:
i. gx, ii. gy, iii. gz correspond to the x, y, and z gradients, respectively.
a. applied during the echo suggests the gradient applied during the readout phase.
b. applied during the RF transmission implies the gradient applied during the RF pulse transmission.
c. applied between the RF and the readout indicates the gradient applied between the RF pulse and the readout phase.
The correct match-up would be:
b) i. gx - b, ii. gy - c, iii. gz - a
i. gx (gradient along x) is typically applied during the RF transmission.
ii. gy (gradient along y) is usually applied between the RF and the readout.
iii. gz (gradient along z) is applied during the echo.
This arrangement aligns with the typical sequence of gradients used in MRI during different phases of the imaging process. The correct match-up would be b) i. gx - b, ii. gy - c, iii. gz - a
