| Zusammenfassung | Novel cancer therapies based on magnetic nanoparticles (MNP) share the need for a Quantitative MNP imaging operating within tolerable measurement times. Magnetorelaxometry tomography (MRXT) has proven its feasibility for quantitative MNP imaging in phantom studies. In MRXT, different regions of a spatial MNP distribution are consecutively magnetized and their magnetization decay is recorded by a sensor array. These magnetizing fields are generated by a number of small excitation coils placed around the body. In conventional MRXT (cMRXT), each coil is used one by one to magnetize the MNP distribution. Hence, the total measurement duration is determined by the total number of coils used. Here, we present experimental results of a simultaneous excitation approach “sMRXT” where multiple excitation coils are simultaneously applied for regional magnetization with the aim to reduce the total measurement duration while preserving reconstruction quality. |
