[The development of fiber-based MR imaging technique].

It has been several decades since the Magnetic Resonance Imaging was introduced to the public as a measure of clinical imaging diagnosis in the 1980's. Time has witnessed increasingly advanced structure and imaging technique. Now, fiber is used as the media to transmit signals of MRI. Manufacturers are competing to release new and creative imaging technique to customers, which has made it faster, more accurate and more convenient for MR imaging. This article briefly introduces latest MR devices with fiber transmission and summarizes their hardwares and softwares so as to provide reference to hospitals that will purchase these devices.
