| 目的 本文旨在评价网络附加存储技术在PACS临床应用中的意义。方法 以单DICOM传输进程方式,分别从PACS长期归档系统中调取4种不同类型的影像检查各100例,测量计算出图像调取速率;以多DICOM传输进程方式,分5组从PACS长期归档系统中调取相同内容的影像检查各100例,测量计算出图像调取速率。比较分析单传输进程与多传输进程情况下的结果。结果 在单传输进程的情况下,影像可以实现快速调取,数字化X线图像可以实现1~3秒内完成单个检查的调取,CT与MR图像可 |

| Objective Information technologies were pushing the development of PACS clinical applications. Network attached storage technique is good at its performance, with successful application in IT industries. This article is to evaluate the application of Network Attached Storage technique in PACS. Methods Using a NAS as long-term archiving system storage unit, on which 15.5 terabytes available for images; both PACS long-term archiving system and NAS unit are configured to be connected at 2 Gbps through Ethernet switches via CIFS. Through single DICOM association, 100 studies of four different modalities are retrieved from PACS long-term archiving system. Through multiple DICOM association, five group of which, images are retrieved from PACS long-term archiving system. With start time, end time, image count and study size logged, calculate the velocity of retrieving a study or an image. Make a comparison of single and multiple DICOM associations. Results Centricity Enterprise Archive manages to send one copy of digital radiography study to hosts within 1－3 seconds and manages to send one copy of CT or MRI study at the rate of 30－40 images per seconds throughout single DICOM association. In case of multiply DICOM associations, the rate does not differ much from that of increasing the number of associations. Conclusion NAS-based PACS long-term archive has a fast and steady performance. It could be a perfect match of the PACS clinical applications. |
