Previously, we explored the use of dielectric pads
containing water and barium titanate beads to enhance
imaging of the cervical spine. One drawback to that
approach was the volume of dielectric required for
enhancement. In this work, we quantify the performance
of a ultra high dielectric constant (uHDC) package
containing monolithic blocks of relative permittivity
~800. This package is reduced in volume relative to our
previous configuration. SNR gains of 20 40% were
observed on discs C1 C4. Gains of about 10% were found
on C5, and a slight loss on C6. Average reduction of
system power was 64.18%.
