Table I.
Resolution, applied gradients (G) number of encoding steps (N), and slice thickness; x is the frequency en coding direction, vertical on images, y − is horizontal phase encoding direction, z − is slicing (depth) phase encoding direction. The table also gives the total field of view (FOVy) in the y direction, which is larger than FOV of the presented figures, zoomed on the most interesting features. In the y direction, FOV has no clear boundary and the image gradually fades due to the loss of signal away from the coil resonance and due to the limited geometrical coverage of the coil. Approximately it is 110 mm. The product FOV · Gmax/ 2Bm is less than 1%, so the concomitant gradients are not important.
