A comprehensive
range of tests in one compact unit that can be measured include:
Slice thickness, slice orientation, interslice gap, magnetic
fields homogeneity, radio frequency signal uniformity, spatial
resolution in positive and negative contrast, and modulation
transfer function.
The phantom can also be used to evaluate quadrate setting,
baseline correction, aspect ratio, and single Tl and T2
values.
The phantom is constructed of non-magnetic materials. It
is 9" in diameter, with two inserts, and is designed
to be filled with an MRI signal-producing solution. One
insert is a series of concentric conic sections. The other
insert is made up is six sections: one for positive contrast
resolution, one for negative contrast resolution, two for
slice evaluations, and two star patterns. A void between
these inserts provides a fully flooded area.
