The coordinate system used in the numerical experiments. The coordinate origin was set at the center of the sensor coil located at the center of the array. The plane at x = 0 cm is shown. The coordinate of the upper left, the upper right, and the lower sources are (0, −1, −6), (0, 1, −6), and (0, −1.6, −7.2) cm, respectively. The circle indicates the boundary of the sphere used for the forward calculations. The center of the sphere was set to (0, 0, −12).
