Intravascular magnetic resonance imaging (MRI) [PDF]
, 2014 This chapter discusses the advantages of using MRI in intravascular operations. Beginning with a brief explanation of some sample intravascular MR operations, the chapter goes on to outline the visualization problem of catheters under MRI. Some of the fundamental catheter coil designs are shown and a range of imaging techniques for catheter tracking ...
