【摘要】：影像存档与传输系统(PACS)是一种医学影像信息管理系统,其主要功能是对数字医疗设备所产生的数字化医学影像信息进行采集、传输、存储、管理和图像后处理,并且实现医学影像的在线查询、调取和显示等功能。近年来,数字医疗成像设备在医疗领域的应用日益增加,由这些数字医疗影像设备所采集的图像信息是非常重要的,它们可以作为医生诊断的依据,还可以应用到医院教学和研究等方面。然而很多医院对于图像信息缺乏有效的管理,影像资料的丢失现象时有发生,这为后续病人医疗信息的查找和调阅带来诸多的问题。另一方面,医院影像检查流程很多都停留在手工登记信息的原始方法上,无法实现病人信息自动录入设备,这也给医生的工作带来很大的不便。在此前提下,如何将医学影像进行传输存储并实现病人信息的共享成为医疗信息化领域的研究热点。鉴于此,本课题设计开发一款医学影像高速传输系统,主要完成了如下三个方面的工作:1、对DICOM标准中的医学影像传输存储过程的模型和原理进行分析与研究,基于开源DCMTK库和MFC框架设计并实现了医学影像传输存储功能。该功能具体将影像设备检查出的图像通过网络传输到PACS服务器,实现了影像信息的统一归档存储。2、对DICOM协议中的Worklist通信服务的实现原理和方法进行了深入研究,设计实现了影像传输系统的Worklist通信服务功能。该服务功能通过实现工作站登记的病人信息与检查设备的工作列表之间的通信,简化影像检查流程,提高了医生的工作效率。3、针对医学影像在多任务并发传输过程中会出现速度过慢甚至卡死的问题,基于Boost库优化系统,添加了线程池功能模块,解决了医学影像的多任务并行发送的问题。提高了影像传输的速率,也提升了系统的稳定性。
[Abstract]:Image Archiving and Transmission system (PACSS) is a kind of medical image information management system. Its main function is to collect, transmit, store, manage and post-process the digital medical image information produced by digital medical equipment.And the realization of medical image online query, retrieval and display functions.In recent years, the application of digital medical imaging equipment in the medical field is increasing. The image information collected by these digital medical imaging devices is very important, and they can be used as the basis for doctors' diagnosis.It can also be applied to hospital teaching and research.However, many hospitals lack effective management of image information, and the loss of image data occurs from time to time, which brings a lot of problems for the subsequent search and reading of medical information for patients.On the other hand, many hospital image examination processes stay on the original method of manual registration information, which can not realize the automatic input equipment of patient information, which also brings great inconvenience to the work of doctors.Under this premise, how to transmit and store medical images and realize the sharing of patient information has become a research hotspot in the field of medical information.In view of this, this subject designs and develops a medical image high-speed transmission system, mainly completes the following three aspects of work: 1, analyzes and studies the model and principle of medical image transmission stored procedure in DICOM standard.The function of medical image transmission and storage is designed and implemented based on open source DCMTK library and MFC framework.This function concretely transfers the image checked out by the image equipment to the PACS server, realizes the unified archiving and storing of the image information. The realization principle and method of the Worklist communication service in the DICOM protocol are deeply studied.The Worklist communication service function of image transmission system is designed and implemented.The service simplifies the image examination process by communicating the patient information registered by the workstation with the work list of the inspection equipment.The efficiency of doctors is improved. Aiming at the problem of slow speed or even stuck in the process of multi-task concurrent transmission of medical image, the function module of thread pool is added based on the optimization system of Boost library.The problem of multi-task parallel transmission of medical image is solved.It improves the speed of image transmission and the stability of the system.
