A study of the noise performance of a planar coil array in the presence of ultra-high dielectric constant (uHDC) material was undertaken. We measured changes in the noise standard deviation and correlation matrix of a 4 channel flex array due to manipulation of uHDC block locations, with blocks either fully overlapping a single channel or straddling two channels. Overlapping a block with a coil element increased the noise of that element, while reducing next-neighbor noise correlations. Further research into this effect could lead to the design of more optimal dielectric configurations that achieve greater SNR.
