【摘要】 本文主要介绍了对医学胶片扫描处理的设计与实现。论文主要涉及三个方面：医学胶片图像的采集、DICOM文件解析与构造和DICOM文件归档。在第一部分中首先对TWAIN标准进行了详细介绍，然后给出图像采集的具体实现方法，并对不同的传输方法进行了比较。在第二部分中介绍了用于实现PACS系统的DICOM标准，对DICOM标准的总体结构及文件的格式进行了详细的描述，给出了DICOM文件的解析方法和构造DICOM文件的方法。在第三部分中对DICOM标准的消息交换机制及DICOM上层协议进行了详细的讲解，给出了使用Windows Sockets实现DICOM应用实体之间的通信的具体步骤。 基于DICOM标准的胶片扫描处理系统解决了医用胶片的数字化归档问题，并以一种符合目前工业标准的格式进行存储，具有很高的应用价值。该系统结构合理、界面友好、操作方便，具有显著的经济效益和社会效益。更多还原

【Abstract】 This paper deals mainly with the design and implementation of medical films scanning and processing. There are three important parts in this thesis: medical films image acquisition, DICOM files parsing and construction and DICOM files archiving. In the first part of this paper, the TWAIN standard is described in detail firstly, then an implementation of image acquisition is presented, and a comparison of different data transfer modes is made. In the second part, the DICOM standard that is used for the implementation of PACS is introduced, and a detail description of the main architecture of the DICOM standard and the DICOM file format is made, with a method for parsing and construction of DICOM files is given. In the third part, the DICOM message exchange and upper layer protocol are explained in detail, and the implementation of the communication between DICOM application entities using Windows Sockets is given.The accomplishment of films scan processing system based on the DICOM standard resolves the problem of medical films digitized archiving, using a industrial standard format for storage, having high value for applications. The system is characterized by rational structure, good user interface, easy to operate, and can bring us remarkable social and economic benefits.更多还原
