试试RadiAnt DICOM Viewer自动播放包!这个是绝对地快速,CD/DVD的播放软件不需要在Windows XP SP3, Vista, Windows 7, Windows 8, Windows 8.1和Windows 10上安装,也不需要另外安装任何软件或程序。(如:NET,Java)。




RadiAnt DICOM Viewer为图片操作和测量提供了以下基本工具:

  • 流畅地镜头远近调节和摇摄
  • 亮度和反光调节,反色模式
  • 预置计算机断层扫描((如肺、骨头、等等)窗口的设置
  • (90度、180度)图片旋转、(水平和垂直)图片翻转
  • 分段长度
  • 圆形/椭圆形和其范围内的中间、最小、最大参数值(如,计算机断层照相法中Hounsfield单位的密度)
  • 角度值(标准角度和科布角度)
  • 自由绘画的画笔工具


RadiAnt DICOM Viewer是为使客户尽可能有效地利用资源而设计。它不但能在大内存的多处理器和多核系统下运行,也能在旧款内存只有512MB的单核机上运行。



Search and download studies from PACS locations

The PACS (Picture Archiving and Communication System) client feature lets RadiAnt DICOM Viewer query and retrieve studies from other PACS hosts.

Supported service class users/providers are: C-ECHO SCU, C-ECHO SCP, C-FIND SCU, C-MOVE-SCU, C-STORE-SCP (Only transfers initiated from the RadiAnt DICOM Viewer are accepted. If you try to send studies from other PACS nodes without searching them first and starting the download in RadiAnt, they will be ignored).

Received DICOM files are stored in a temporary folder and are deleted when RadiAnt closes.



  • 数字式放射照相术(CR, DX)
  • 乳房X射线照相术(MG)
  • 计算机断层照相法(CT)
  • 磁共振(MR)
  • 正电子发射计算机断层扫描PET-CT (PT)
  • 超声波扫描术(US)
  • 数字血管造影术(XA)
  • 核医学照相术(NM)
  • 二次图片和扫描的图像(SC)
  • Structured Reports (SR)

  • 单色的 (如:CR, CT, MR) 和彩色的 (如:US, 3D重建)
  • 静态图像 (如:CR, MG, CT) 和连续动态图像(如: XA, US)
  • 未压缩和压缩过的图像(RLE, 有损的JPEG, 无损的JPEG, JPEG 2000)




当浏览不同面的解剖系列图像时,显示出的交叉参考线可以更好地展示相互间的联系 (如,磁共振图像)。


为了创建优秀视觉呈现和专业的出版——RadiAnt DICOM Viewer能够将DICOM文件转换成为JPEG格式图片(压缩的)或者BMP格式图片(未压缩的位图)和WMV视频(Windows媒体视频)。




RadiAnt DICOM Viewer所提供的MPR工具可以用来在正交平面(冠状的、径向的、轴向的、倾斜的,取决于图像的基本平面)中重建图像。

重建过程相当迅速: 可以在大约三秒钟的时间,由超过2000张轴向CT断面切片重建出冠装位图像(在现代英特尔酷睿i7系统下)。

3D volume rendering

The 3D VR (volume rendering) tool lets you visualize large volumes of data generated by modern CT/MR scanners in three dimensional space. The different aspects of the data set can be interactively explored in the 3D VR window.

This tool lets you rotate the volume, change zoom level and position, adjust color and opacity, measure length and show hidden structures by cutting off the unwanted parts of the volume with the scalpel tool. The image is rendered progressively to maintain fluid operations even on slower machines.

Time-intensity curves

RadiAnt DICOM Viewer lets you visualize the lesions' enhancement behavior (e.g. in Breast MRI) by plotting time-intensity curves (TICs).

Different types of curves can be obtained: Ia - straight (the signal intensity continues to increase over the entire dynamic period) / Ib - curved (the time-signal intensity curve is flattened in the late postcontrast period), II - plateau (the signal intensity plateaus in the intermediate and late postcontrast periods) or III - washout (the signal intensity decreases (washes out) in the intermediate postcontrast period).

Multi-touch support

If you have a Windows 8 or Windows 10 touch-enabled device, you might find that gestures (motions that you make with one, two or more fingers) are easier to use than a mouse or keyboard. RadiAnt DICOM Viewer enables users to make use of the array of multi-touch gestures:

  • Touch the image with one finger and move it to browse through images of the displayed series.
  • To zoom in or out, touch two points on the image, and then move your fingers away from or toward each other. Drag the image with two fingers to move it and show invisible parts of zoomed image.
  • You can change the window settings (brightness/contrast) by touching the image with three fingers and moving them up/down (brightness) or left/right (contrast).

3D MPR/MIP/MinIP/Avg is here
December 21, 2016
As 2016 comes to an end, we have a new beta version for you with another long awaited major feature - 3D MPR viewer. It lets you view the cross-section of the volume in an arbitrary plane. You can also increase the thickness of a slab in MIP (maximum intensity projection), MinIP (minimum intensity projection) and Average modes. It still lacks some UI controls, however, the core functionality is almost there and we'll be very happy if you give it a try!

We also have a maintenance stable release (3.4.2) with some small improvements and bug fixes, you can download it here.

The RadiAnt Team would like to wish you the gift of good cheer this holiday season and may it stay with you throughout the coming year!
RadiAnt DICOM Viewer 3.4.1
September 20, 2016
In this new version we have implemented manual series synchronization. Now you are able to synchronize two or more series coming from different studies. This feature can be also useful when patient's position differs within series of the same study.

Additionally, automatic synchronization mode was improved - now it can work for series with similar (but non-parallel) planes forming the dihedral angle up to 5 degrees. This is often the case with the MR studies.

We've enhanced the DICOM tags window, you can search all DICOM elements for a specific text. You can also quickly show the displayed DICOM file in Windows Explorer.

Last but not least, there are a few bug fixes and performance improvements.

Download RadiAnt DICOM Viewer 3.4.1
RadiAnt DICOM Viewer 3.0.2
April 18, 2016
Here comes the 3D Volume Rendering feature! Download the new version, RadiAnt DICOM Viewer 3.0.2 and enjoy the interactive volume exploring now.

Read more about this cool new tool in our updated manual.

As always, there are some other minor improvements.
Volume Rendering on Microsoft Surface Pro 4

We prepared a short video showing how the capabilities (multi-touch and pen support) of Microsoft Surface Pro 4 can make Volume Rendering a breeze, with RadiAnt DICOM Viewer, of course :-) https://www.youtube.com/watch?v=za5i7bX6nV4
