| Outline of Final Research Achievements |
Diagnosing cancers and cardiovascular diseases at an early stage by magnetic particle imaging (MPI) has been expected. In MPI, however, strong gradient magnetic field strength is needed to obtain high image resolution. In this study, the new algorithm that can make image reconstruction of the image data acquired fast with high image resolution was proposed. The validity of the image reconstruction method was evaluated by numerical analysis, and satisfactory image quality was obtained compared with the conventional method. In addition, the two-dimensional MPI system was constructed and validity of the proposed image reconstruction method was clarified experimentally. Furthermore, the new signal acquisition method for detecting a magnetization signal by vibrating a magnetic nanoparticle without using an alternating current magnetic field was proposed, and the feasibility was shown.
