 ### 概念
 
 **Application Entity (AE)**，Application Entity 代表DICOM通信中的一个终端，可以代表一个系统或者一个程序。每个系统中的AE拥有一个唯一的Application Entity Title (AET) 。AET的要求时不能超过16个字节。一个设备上面可以有很多个AE。

+- CT(Computed Tomography), 计算机断层成像，观察形态和密度
+- MRI(Magnetic Resonance Imaging), 核磁共振成像，可多参数、多序列、多方位成像，在软组织对比度方面具有较高优势
+- PET(Positron Emission Tomography), 正电子发射断层成像，PET 对疾病诊断的灵敏度高，但分辨率低
+- Ultrasound, 超声，可以清晰显示脏器及周围器官的各种断面像，接近解剖真实结构，因其价廉、简便、迅速、无创、无辐射性、准确、可连续动态及重复扫描等优势应用甚广
