DICOM简介
来源:互联网 发布:婚纱品牌 知乎 编辑:程序博客网 时间:2024/06/05 17:06
DICOM是设备、软件之间的通用语言,在没有DICOM之前,爪哇的设备和中国的设备是不通的。即使没有DICOM,可能也会有MIEM(Medical Information Exchange And Management,自己编的)等协议出现,所以说DICOM的出现是技术发展的必然。柏林墙都倒了,世界都是平的,医疗设备,软件间通信也应该是国际化的!

DICOM不是静态的标准,仍不断更新中......
我们为什么要有DICOM?
设备间互联互通的客观需求。
DICOM给我们带来哪些方面的变化?
内容(图像,报告等),传输(工作流),显示,图像处理,内容分发等。
我们常说的DICOM3.0其实是一个不算特别清晰的表述,因为之前根本没有1.0 2.0版本,只有ACR 1.0等。
DICOM的最新release版本是2011版,DICOM标准委员会共有28个工作组(WG),如下:
WG-01: Cardiac and Vascular Information
WG-15: Digital Mammography and CAD
WG-02: Projection Radiography/Angiography
WG-16: Magnetic Resonance
WG-03: Nuclear Medicine
WG-17: 3D
WG-04: Compression
WG-18: Clinical Trials and Education
WG-05: Exchange Media
WG-19: Dermatology
WG-06: Base Standard
WG-20: Integration of Imaging and InfoSystems
WG-07: Radiotherapy
WG-21: Computed Tomography
WG-08: Structured Reporting
WG-22: Dentistry
WG-09: Ophthalmology
WG-23: Application Hosting
WG-10: Strategic Advisory
WG-24: Surgery
WG-11: Display Function Standard
WG-25: Veterinary Medicine
WG-12: Ultrasound
WG-26: Pathology
WG-13: Visible Light
WG-27: Web Technology for DICOM
WG-14: Security
WG-28: Physics
这些工作组负责各自领域内标准的修订和更新。待修订和更新完备后,DICOM标准委员会将会发布新版本的DICOM标准。有兴趣的可以去看一下dicom委员会各工作组的工作日历(http://workspaces.nema.org/dicom/Lists/Calendar/calendar.aspx)。
在工作组的努力下,每年保持10个supplement、100个correction的更新。

第一章是对整个DICOM标准做一个简单介绍,相当于前言部分。
第二章是DICOM一致性声明,第三章是各IOD的描述,第四章讲述DICOM服务类,第五章是编码,第六章为数据字典,第七章第八章为DICOM中的通信模块。这也是DICOM中最核心的模块,IOD和服务类以及DICOM通信。一般的DIOCM图像库中,核心部分都是Data和Net包。
