The new development of magnetic resonance imaging

The development of MR focuses in high performance magnet,twin grads technology,phased array coil and parallel imaging technology.These technologies raise SNR of images and shorten the imaging time.Many new clinical technologies have been opened out in order to solve the problems which have been faced for a long time,such as arti-facts,imaging of heart and so on.They also meet the needs of clinic and scientific research.Other advancements in MRI technology have made in high performance computer,advance data management and so on.
