WebThe field gradients Gx , Gy , and Gz are typically designed such that the origin ( x = y = z = 0) is at the center of the imaging volume and that moving in one direction from the origin will give fields that add to B0 and moving in the other direction will produce fields that oppose it. WebApr 2, 2024 · Gradient echo sequences (GRE) are an alternative technique to spin-echo sequence s , differing from it in two principal points: utilization of gradient fields to generate transverse magnetization flip angles of less than 90° Compared to the spin-echo and inversion recovery sequences, gradient echo sequences are more versatile.
