Reconstruction results of the 3D phantom. The space covered by the three letters is 90 × 90 mm² for each layer. The distance between the individual layers is 32 mm. The letters consist of capillaries with an inner diameter of 1.3 mm filled with Perimag with a concentration of 8.5 mg_Fe ml⁻¹. The reconstructed images show the three letters without interference of the other layers. The total image acquisition time of the 13 slices was 26 s
