Specialized RF coil array development for MR imaging

There have been a number of technology changes in MRI since it's introduction in the 1980's. These include changes in magnet technology, gradient technology and coil technology. The ongoing developments in the RF subsystem are probably the most profound changes in MRI system development in the last several years.At the MRI unit of the hôpital Notre-Dame of the Centre Hospitalier de l'Université de Montréal, the research and clinical emphasis are on neuro and musculoskeletal imaging and MR guided intervention. To enhance our research capabilities in these fields, we have developed a coil fabrication laboratory. In the last 18 months, we have developed and fabricated multi element coils for human and animal imaging, and endovascular coils for interventional MR.In this research project, we intend to investigate RF coil designs in 2 specific areas: endovascular coils for interventional MRI and large multi channel coil arrays.
