Conflict of interest statement

Certain commercial equipment, instruments, software, or materials are identified in this paper in order to specify the experimental procedure adequately. Such identification is not intended to imply recommendation or endorsement by NIST, nor is it intended to imply that the materials or equipment identified are necessarily the best available for the purpose.

FIGURE 1
Magnitude of the transmit magnetic field (left) and transceive phase (right) for an axial slice of a two‐compartment cylindrical phantom (details on compartment EP values are provided in the next sections). The phantom was scanned at 2.5 mm isotropic resolution using the RF map sequence [8]. The plastic boundary separating the two compartments was approximately 2.5 mm thick. This boundary region is noisy due to the lack of MR signal in both the magnitude and phase maps.
FIGURE 2
FIGURE 2
Schematic representation of a two‐compartment cylindrical liquid phantom used for EP mapping in [20]. The phantom consists of an outer hollow cylindrical and an inner cylindrical compartment. The total length of the phantom is 21.5 cm. The inner radius of the hollow cylinder is 6.875 cm, while the inner cylinder has an inner radius of 3.1 cm and is offset by 0.5 cm from the central axis of the hollow cylinder. The scaffold that contains the liquid solutions has a uniform thickness of 0.5 cm, except at the interface between the two compartments, where it is reduced to 0.3 cm.
