RadiAnt Mascot
RadiAnt 是一个医学图像的PACS DICOM浏览器
"(...) What I also accidentally discovered is an extremely lightweight DICOM viewer with basic viewing options - perfect for being CD distribution, called RadiAnt. (...) As 3 year radiology resident I have already seen dozens of bundled viewers on CDs... this one is at least 300% faster than any I've seen so far. It also allows you to include your own company logo to the splash screen it shows while loading."

3D snapshots and VR movies

3D snapshots and VR movies
We have added new features to the VR window in our latest beta version (5.1.14).

3D snapshots let you save the states of the VR view (rotation / position / zoom / window / scalpel / etc.) and quickly restore these states.

You can now create high quality (up to 4K, 60fps) movies based on the 3D snapshots. There is also a quick movie tool for creating videos with a simple 360/180 degree rotation.
Image filters and 3D VR/MPR improvements

Image filters and 3D VR/MPR improvements
Our latest beta version (5.1.6) brings a new feature: image filters (sharpen, smooth, edge, emboss).

There are also a few improvements: unlimited undo history for the VR's scalpel tool, progressive rendering (3D VR/3D MPR) when using GPU acceleration (fluid interactions), and support for extended mouse buttons (back/forward).
RadiAnt DICOM Viewer 5.0.1
June 30, 2019
RadiAnt DICOM Viewer 5.0.1
The long-awaited Local Database feature is now available in RadiAnt. It allows you to import DICOM studies from CD/DVD discs, USB flash drives, local and network folders or PACS servers, and store them on your local hard drive so that they can be easily accessed at a later date. You can also access the database to organize and quickly find studies in your collection of DICOM files.

We also added a new feature to the VR module. 3D models created in RadiAnt can be exported to STL files, which can be opened in alternative 3D modeling software and used for 3D printing.

DICOM Viewers for Veterinary Medicine

DICOM Viewers for Veterinary Medicine
It is not very often that studies comparing different DICOM viewers are published. Recently, eight DICOM viewers were reviewed for use in veterinary medicine in the Journal of Digital Imaging.

RadiAnt was named a favorite Windows DICOM-viewer of the observers. Overall it scored 8.90 points (the winning viewer for MacOS got 8.96). For your information, the reviewed version of RadiAnt was 3.4, so many new features and improvements have been added since.

RadiAnt DICOM Viewer CD/DVD Viewer



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)。



Basic tools for manipulation of images


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

Lightning fast performance


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。



PACS client feature for searching and retrieving studies

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.

Multiple formats of DICOM files supported



  • 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)

Browse and compare multiple series of images




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)。

Export DICOM files to BMP, JPEG, WMV


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)。



2D and 3D Multi-planar reconstructions (MPR)


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 (VR)

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.

PET-CT image fusion

Time-intensity curves (TIC)

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).

Support for multitouch features on Windows 10

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).
