Specialized RF coil array development for MR imaging

自20世纪80年代S引进以来，磁共振成像技术发生了许多变化，包括磁体技术、梯度技术和线圈技术的变化。射频子系统的持续发展可能是近几年来磁共振成像系统发展中最深刻的变化。在蒙大略省L大学医院圣母院的磁共振成像单元，研究和临床重点是神经和肌肉骨骼成像以及MR引导的介入。为了增强我们在这些领域的研究能力，我们开发了一个线圈制造实验室。在过去的18个月里，我们开发和制造了用于人体和动物成像的多元素线圈和用于介入性磁共振的血管内线圈。在本研究项目中，我们打算研究两个特定领域的射频线圈设计：用于介入性磁共振的血管内线圈和大型多通道线圈阵列。

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.
