Representative results from previous studies replicated, for the sake of validation, using the current DGF formalism. a) DGF results matching Figure 5 in Ref. (9): UISNR as a function of radial position in the transverse plane of a 30 cm diameter dielectric sphere for varying B0. b) DGF results matching Figure 2 in Ref. (16): SNR as a function of frequency for a 12 cm diameter loop coil, its axis aligned with the B0 field direction, suspended 2 cm above a 20 cm diameter dielectric sphere. Values are calculated for a voxel 5 cm beneath the surface of the sphere (on axis) and normalized to the SNR at 430 MHz. c) DGF results matching Figure 7 in Ref. (15): UISNR on the axis of a 20 cm radius dielectric cylinder as a function of frequency is compared for an optimal lossless cylindrical current surface built of magnetic dipoles only and a similar optimal current surface built of both magnetic and electric dipoles. d) DGF results matching Figure 5 in Ref. (14): SNR of a cylindrical window coil as a function of coil position at 40 MHz in a 20 cm radius dielectric cylinder. Each plot corresponds to a different position of the voxel of interest along the radial dimension of the cylinder.
