Abstract(in English) | MPI (Magnetic Particle Imaging) is a method to image magnetic nanoparticles accumulated in the human body, and is expected for the application of in-vivo diagnosis to malignant tumor. We developed a high-sensitivity AC magnetic field measurement system for the imaging of magnetic nanoparticles. In developing the system, we used cooled pickup coil to reduce the thermal noise. We also detected a third-harmonic signal generated from the nanoparticles in order to reduce the interference of the excitation field. When we used the excitation c field with frequency of 3 kHz and amplitude of 1.6 mT, we could successfully detect 100 μg of magnetic nanoparticles located at the depth of 100 mm. Aiming to detect much less magnetic particles, we reduced the amount of magnetic nanoparticles to 10 μg, 5 μg and 1 μg. We have succeeded in detecting signal from these magnetic particles located at the depth of 50 mm. |
