Synopsis

Prior work has explored the use of dielectric materials to enhance imaging of the brain and spine with rectangular blocks. One area that has not been examined to date is knee imaging, where space constraints limit the use of blocks. In this work we evaluate the performance of an ultra-high dielectric constant (uHDC) curved plate (εr ~ 4500) for knee imaging in a clinical array at 3T. SNR gains of 9 to 71% percent were observed across the patella and patellar cartilage. Transmit efficiency increased up to 100% close to the material, with an increase in transmit inhomogeneity.
