最近客户需要做一个能简单查询展示医疗照片（CT，B超等）小工具，所以开始做这些方面的调研。

这些医疗照片都有行业的标准，DICOM。摘录Wiki的介绍：

DICOM (Digital Imaging and Communications in Medicine)   is a standard for handling, storing, printing, and transmitting information in medical imaging. It includes a file format definition and a network communications protocol. The communication protocol is an application protocol that uses TCP/IP to communicate between systems. DICOM files can be exchanged between two entities that are capable of receiving image and patient data in DICOM format. The National Electrical Manufacturers Association (NEMA) holds the copyright to this standard.[1] It was developed by the DICOM Standards Committee, whose members[2] are also partly members of NEMA.[3]

DICOM enables the integration of scanners, servers, workstations, printers, and network hardware from multiple manufacturers into a picture archiving and communication system (PACS). The different devices come with DICOM conformance statements which clearly state which DICOM classes they support. DICOM has been widely adopted by hospitals and is making inroads in smaller applications like dentists' and doctors' offices.

这里提到PACS，要开发的系统也需要有一个这照片的管理服务器。 

开上上网找了了一些产品和SDK

Atalasoft SDK

Accusoft

LEAD Tool

ClearCanvas

没有太多的时间做深入的了解，只是每个工具简单的安装、测试了一下。最后选择LEAD TOOL和ClearCanvas研究。LEAD TOOL价格中等功能比较完善，例子很多；ClearCanvas有Community版本，这个是开源的。
