The theme of the research is embedded in the context of INSERT, a European project aiming at realization of a MRI/SPECT system for simultaneous functional and anatomical brain imaging. High static magnetic field, rapidly switching magnetic gradients and RF signals present in MRI, interfere with the working of a traditional SPECT system. Also the materials used in traditional SPECT system, generate artifacts in MRI imaging, reduce homogeneity and lower SNR. In this thesis, both theoretical and experimental quantification of such effects at system and component level will be undertaken. Consequently, new mechanical design with MRI compatible components and appropriate shielding will be the most likely results of this research.
