摘要
通过1999年度北美放射学会影像学设备展示,总结了影像学设备发展的两大趋势。并从CT,MR两方面进行了具体介绍。(1)CT设备的进展,重点介绍了宽探测器多层采集螺旋CT的进展和应用,以及常规CT设备的进展。(2)MR设备的进展,包括中场超导开放式MR设备、专用MR设备、MR设备的梯度场强度、开放型磁体设计、磁共振血管成像、功能性MRI、磁共振波谱成像及其他软、硬件的发展等方面。
From the exhibition on1999 RSNA, two general tendencies of imaging equipment were concluded and detailed introduced from two aspects on CT and MR. (1) The development of CT. The advance and ap-plication of multi -slice CT and routine one were emphatically introduced. (2) The development of MR. It was depicted on several aspects, which involved of the super -conductor open MR scanner with middle field, the special MR scanner, the strength of MR gradient field, the design of open style magnet, MR angiography, functional MRI, MR spec-troscopy, and others progress in software/ hardware.
