font-size: 15px; font-family: 宋体;">2004年64排CT的出现，探测器不仅在z轴覆盖范围上较16排加宽一倍，同时探测器的切割实现了高分辨的切割模式。64排不仅提高了图像质量，而且使快速大范围高分辨率扫描及心脏扫描成为临床常规。由此，64排CT以其全身快速、大范围、高精度扫描，成为目前医院的主力机型。到目前为止，国内64排装机量已经超过1000台。</span></p><p style=""><span style="max-width: 100%;

word-wrap: break-word !important; box-sizing: border-box !important; font-size: 15px; font-family: 宋体;">最近几年我们发现层排大战开始逐渐降温，各大国际生产厂家在超高端</span><span style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important; font-size: 15px; font-family: 宋体;">CT上开始转而关注“更多的临床应用”和“更低的成像剂量”，如大范围4D功能成像，剂量控制，能谱成像，肿瘤性质鉴别等。2008年各生产厂商分别推出超高端CT，虽然发展思路不尽相同，但在4D功能成像，高清图像质量，和降低扫描剂量方面却达成共识。在刚刚过去的RSNA2013，GE推出RevolutionCT，实现了能谱、高清、时间分辨率和覆盖范围的统一，代表了今后的超高端CT的技术发展的方向。超高端CT技术发展也深刻地影响着64排CT的发展趋势。</span></p><p style=""><span style="max-width: 100%;
