【摘要】 医学图像数字成像和通信(D ig ita l Im ag ing and Comm un ications in M ed ic ine,D ICOM)标准是美国电气制造商联合会(NEM A)和美国放射学会(ACR)为了医学图像的存储和传输而制定的标准,在医学上得到广泛的应用。但该标准目前没有充分定义图像语义内容,从而使得实际中不能有效的实现D ICOM的基于语义的应用。本文讨论了医学图像中的语义描述层次结构,概述了D ICOM标准中对图像的描述方法并指出了该标准对图像语义内容描述的不足,给出了使用D ICOM标准中私有属性对D ICOM图像语义内容进行扩充的方法。更多还原

【Abstract】 The Digital Imaging and Communications in Medicine(DICOM) Standard was developed by National Electrical Manufacturers Association(NEMA) and the American College of Radiology(ACR) for medical image archiving and communication.The Standard is widely used in medicine now.But it does not define image semantic content sufficiently,so there is a difficulty in the implementation based on semantic content.In this article are discussed the semantic hierarchy structure in medical image and the method to describe the image content used in the DICOM Standard.We point out the limitations of DICOM in image semantic content description,and then set forth a way to extend the semantic content description by using DICOM private attributes.更多还原
