Abstract
This paper presents interim results in the development and implementation of a selection and focus field generator for Magnetic Particle Imaging. The construction of a multi-coil field generator specifically designed for the purpose of diffusion imaging of the brain is a complex task. The degrees of freedom in topological decisions with interconnected dependencies require careful considerations. The preliminary results of the initial constructional and electrical concept based on simulations are presented.
A focus in decision making was placed on the manufacturability of the coils and their thermal properties. The conducted experiments indicate that the manufacturing and fixation of the core coil module presents a significant challenge.
Additionally, more advanced cooling strategies have been pre-evaluated, as the intended cooling setup has been found to be inadequate in the visualized setup.
