摘要
受益于高科技特别是计算机技术的飞速发展,磁共振成像设备近年来呈现出飞速发展的态势,体现为超高场、短磁体、开放性以及低损耗等方面的高性能磁体、高性能的双梯度系统以及减低涡流、静音降噪技术,多通道相控阵线圈以及并行采集技术等,提高了图像信噪比,缩短了扫描时间,为许多新技术在临床的运用奠定了硬件的基础,很好地解决了困扰临床很长时间的伪影、心血管成像等难题,满足临床与科研的需要。高性能的计算机系统、后处理工作站、DICOM3.0兼容、以及人性化的操作界面是磁共振另一特点。
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 artifacts, 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.
