This dissertation addresses topics related to developing interventional assistant devices for Magnetic Resonance Imaging (MRI). MRI can provide high-quality 3D visualization of target anatomy and surrounding tissue, but the benefits can not be readily harnessed for interventional procedures due to difficulties associated with the use of high-field (1.5T or greater) MRI. Discussed are potential solutions to the inability to use conventional mechatronics and the confined physical space in the scanner bore.The 1.5T GE scanner allows for manual setting of the gains to the consistent values, thus ensuring comparability. ... The receiving imaging coils used for the experiments were two channel medium size flex coil for the 3T scanner and four channel cardiac coil for the 1.5T ... the spherical phantom, the other one on top ( Fig.
