FIG. 5.

Magnitude of E-field in the body of the NORMAN heart centered model for channel 2 shown in an axial slice through the cardiac region for the Idealized Coil Model (a). b: Differences from ICM when using FCM with quadrature normalization, active decoupling by fitting and active decoupling by pickup coils. c: Normalized RMS difference in |E| between FCM and ICM for the eight channels; the dashed lines correspond to averages over all channels. Stronger deviations are seen here compared with the B₁⁺ fields for the same slice. d–f: As parts (a–c) but for a different axial slice in the NORMAN heart centered model–a slice that was not used to calculation the normalization matrices. Larger differences between the Idealized Coil Model and the Full Coil Model exist in this slice.
