Four of the resulting image types are automatically loaded in the
viewer:
Magnitude Image
This is the standard MRI magnitude image.
Relative stiffness Map (Elastogram)
This image contains the magnitude of the complex shear modulus. The
displacement field is to be converted to a relative stiffness map by solv
ing the Helmholtz equation. The processing assumes local uniformity,
incompressibility, and a material density equal to that of water.
Relative stiffness 95% Map
Areas in the relative stiffness map where the confidence map shows val
ues of less than 95% (950 in the scaled confidence map) are marked
with a checkerboard pattern. The remaining areas represent those
regions where the wave amplitude was highest, providing the most reli
ability in the relative stiffness map.
