Abstract: | Magnetic resonance imaging (MRI) has traditionally been used exclusively in a role for patient diagnosis. However, it is unlikely
that this role is sufficient for its continued prominence in medical imaging. Instead, the more ambitious role in diagnosis
and also therapy intervention will occur as demand for minimally invasive procedures increases. Fortunately, with recent improvement
in technical specifications and creative pulse sequence design, MRI systems can now provide high quality near-real-time images
that facilitate a variety of image-guided procedures, many based around delivery via catheters. While X-ray opacity is not
available as a means for detecting the progression of the catheter in MRI systems today, a variety of novel hardware devices
have been designed and used for MRI catheter tracking. This report provides a brief review of some fundamental methods for
catheter tracking in MRI.
