Abstract

In this paper we report a progress in the development of the MPI scanner model. Magnetic particle imaging is an emerging diagnostic technique which can be potentially applied for physiological processes observation or fluid dynamics monitoring. The model's design assumes imaging of two dimensional cross-section of samples with a diameter up to 3 cm. The numerical calculations of selection and driving field conducted using the COMSOL Multiphysics FEM software and the custom static magnetic field solver implemented in MATLAB were performed. The results were used to determine the best geometrical parameters of scanner parts, mainly selection and driving coils. The design and construction of selection, driving and receiving coils are presented. The gradient magnetic field generated by coils with current of 2 A was about 1 [T/m]. The first tests of fluid with nanoparticles excitation and signal acquisition were performed.
