3-2
Figure 3-2 shows the cross section of the concentric conical part of the phantom. The aspect ratio is
correct, as is the uniformity of the slice thickness as represented by the uniform widths of dark and light
circular bands.

3.2.3 Magnetic Field Homogeneity
Any distortions in the roundness of the rings can be a result of non-uniformity in the main magnetic field,
as shown (Figure 3-3).
Figure 3-3.
3.3 Flood Section
This section is a typical flood phantom, 9" in diameter by 1.25" thick. It may be filled with any signal
producing solution (Figure 3-4).
