The field of MR imaging has grown from diagnosis via morphologic imaging to more sophisticated diagnosis via both physiologic and morphologic imaging and finally to the guidance and control of interventions. A wide variety of interventional procedures from open brain surgeries to noninvasive focused ultrasound ablations have been guided with MR and the differences between diagnostic and interventional MR imaging systems have motivated the creation of a new field within MR. This review discusses the various systems that research groups and vendors have designed to meet the requirements of interventional MR and suggest possible solutions to those requirements that have not yet been met. The common requirements created by MR imaging guidance of interventional procedures are reviewed and different imaging system designs will be independently considered. The motivation and history of the different designs are discussed and the ability of the designs to satisfy the requirements is analyzed.
磁共振成像领域已从通过形态学成像进行诊断发展到通过生理和形态学成像进行更复杂的诊断，最终发展到对介入操作的引导和控制。从开颅手术到无创聚焦超声消融等各种各样的介入操作都已由磁共振引导，并且诊断性和介入性磁共振成像系统之间的差异促使了磁共振领域内一个新领域的产生。本综述讨论了研究团队和供应商为满足介入性磁共振的要求而设计的各种系统，并针对尚未满足的要求提出了可能的解决方案。回顾了介入操作的磁共振成像引导所产生的共同要求，并将独立考虑不同的成像系统设计。讨论了不同设计的动机和历史，并分析了这些设计满足要求的能力。
