医学图像采集是PACS的重要环节，也是PACS实用化的关键。本文比较了几种常见的图像采集方法，重点介绍了通过DICOM接口的图像采集。在详细阐明了DICOM网络的概念和DICOM消息交换的规范之后，介绍了我们编写的DICOM医学图像采集软件。本软件是在windows平台上利用Socket API编写而成，提供了DICOM标准定义的验证、存储、查询和检索等服务。测试结果表明，本软件能够顺利地与成像设备连接并采集图像。%Image acquisition plays an important role in PACS. In this paper, we compare some currently used methods of image acquisition, and select the acquisition method through DICOM interface in network environment. After describing the concepts of DICOM network and the DICOM message exchange, we summarize the key technique for DICOM image acquisition.Our software is introduced as one solution for image acquisition from digital medical imaging systems. The software is written in Windows Socket API and provides such services as verification, storage, query and retrieve defined by DICOM standard, and acts as the acquisition server for images sent from imaging equipment. Up to now, our software works well with different equipment under different conditions.
