摘　　要：目的:评价数字断层融合技术对组织微细结构的显示,提高对细小病灶的诊断能力。方法:利用Sonalvision Safire系列装置的功能,获得检查部位任意层面断层的影像。结果:该项技术在胸部、骨骼及小关节等影像学检查中具有独特效果。结论:该项技术是一种新兴的X线断层检查技术,避免了普通放射学检查由于组织结构重叠所导致的低敏感性和低特异性等缺点,并且有较好的深度定位能力,将广泛应用到新的临床领域。Objective To evaluate digital tomosynthesis used for displaying micro structure to improve the diagnosis for small focus. Methods Sonialvision Satire series of devices were used to obtain levels of tomographic images as required. Results Digital tomosynthesis behaved well in imaging of chest, bone and facet. Conclusion Digital tomosynthesis eliminates the defects such as low sensitivity and specificity due to structure overlapping, and will be widely applied to new clinical fields.
