| 摘要 |
Methods and apparatuses of the present invention perform imaging using a contrast agent and/or a metamaterials lens, together with a low magnetic field detector. The apparatus according to one embodiment comprises: a field source capable of generating a magnetic field directed to an area in a subject; a low magnetic field detector arranged downstream from the field source, the low magnetic field detector being capable of detecting a low magnetic field signature associated with the area in the subject; and a metamaterials lens arranged downstream from the field source, the metamaterials lens concentrating the magnetic field produced by the field source to the area in the subject, and/or concentrating back the magnetic signature from the area in the subject to the low magnetic field detector. |
