"I am an end-user (patient) who could not wait several minutes for the IntelViewer to load off the CD and then wait long periods of time to load and display views. I downloaded several no cost viewers and found RadiAnt to be the fastest and also the least intrusive. I put the viewer and the 900 images from CT, X-ray and MRI on a stick drive and can take it to treatment facilities along with all my other records. I can run it without disturbing the host computer at the doctor's offices. Thank you for allowing those of us who are non-professionals and do not have funds to purchase expensive software to download this package."

Patient CD/DVD DICOM Viewer

Do you know how frustrating it can be to endlessly wait for a patient CD to open?
Does your viewer require the installation of additional components before the images can actually be viewed?

Try the RadiAnt DICOM Viewer CD/DVD autorun package! It is extremely fast, runs from CD/DVD media without installation on Windows XP, Vista, Windows 7 and Windows 8 systems and does not have any additional software or programming requirements (e.g. .NET, Java).

If the user’s operating system permits, the 64-bit version is opened for better efficiency. On older machines the 32-bit version is used. Approximately just 6MB of overhead data is added to the media.

The logo image displayed after opening the application is fully customizable and can be used to show your company information to your clients.

All the necessary tools close at hand

RadiAnt DICOM Viewer provides the following basic tools for the manipulation and measurement of images:

  • Fluid zooming and panning
  • Brightness and contrast adjustments, negative mode
  • Preset window settings for Computed Tomography (lung, bone, etc.)
  • Ability to rotate (90, 180 degrees) or flip (horizontal and vertical) images
  • Segment length
  • Mean, minimum and maximum parameter values (e.g. density in Hounsfield Units in Computed Tomography) within circle/ellipse and its area
  • Angle value (normal and Cobb angle)
  • Pen tool for freehand drawing

Quick as lightning

RadiAnt DICOM Viewer was designed to use resources as efficiently as possible. It can make use of a multiprocessor and multicore system with large amounts of gigabytes of RAM, but will also run on an old single-core machine with only 512MB RAM.

A 64-bit version is provided for modern systems to keep all opened images in more than 4GB of memory, if necessary. Asynchronous reading lets you browse and process images while they are still being opened.

All of this is available in one very compact application that has an installer size of just over 2MB.

Supports multiple DICOM file types

The software has the capability to open and display studies obtained from different imaging modalities:

  • Digital Radiography (CR, DX)
  • Mammography (MG)
  • Computed Tomography (CT)
  • Magnetic Resonance (MR)
  • Positron Emission Tomography PET-CT (PT)
  • Ultrasonography (US)
  • Digital Angiography (XA)
  • Gamma Camera, Nuclear Medicine (NM)
  • Secondary Pictures and Scanned Images (SC)

Many types of DICOM images are supported:
  • Monochromatic (e.g. CR, CT, MR) and color (e.g. US, 3D reconstructions)
  • Static images (e.g. CR, MG, CT) and dynamic sequences (e.g. XA, US)
  • Uncompressed and compressed (RLE, JPEG Lossy, JPEG Lossless, JPEG 2000)

Compare different series or studies

Multiple series of one study or several studies can be concurrently opened in the same or different windows for comparison purposes.

Series consisting of images that have been acquired in the same plane (e.g. Computed Tomography series before and after administration of the contrast medium) are automatically synchronized by default.

Cross-reference lines are displayed for better correlation of the anatomy when browsing series with different image planes (e.g. Magnetic Resonance study).

Export DICOM files to images and movies

Create visually stunning presentations and professional publications - RadiAnt DICOM Viewer can export DICOM files to JPEG (compressed) or BMP (uncompressed bitmap) images and WMV (Windows Media Video) movies.

One image, an entire series or all opened images can be exported simultaneously.

Displayed images can be quickly copied to the Windows clipboard using the CTRL+C shortcut and can be quickly and easily pasted into Word or PowerPoint documents.

Multiplanar reconstructions

The MPR tool provided within RadiAnt DICOM Viewer can be used to reconstruct images in orthogonal planes (coronal, sagittal, axial or oblique, depending on what the base image plane is). This can help to create a new perception of the anatomy that was not possible to visualize using the base images alone.

The reconstruction process is extremely fast: a coronal series can be created from more than 2000 axial CT slices in approximately three seconds (on a modern Intel Core i7 system).

PET-CT image fusion

Overlay a color-mapped PET image onto a CT scan to obtain anatomical references for regions with increased FDG (fluorodeoxyglucose) uptake values.

Use the ellipse tool to measure maximum, minimum and average values of SUVbw (Standardized Uptake Value calculated using body weight) in a specified area.

Image fusion can also be applied to other imaging modalities, such as Magnetic Resonance, e.g. DWI images can be fused with T1 or T2-weighted scans.

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 for Windows 8

If you have a Windows 8 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 Windows 8 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).

Multilingual interface

Thanks to our community, RadiAnt DICOM Viewer interface has been translated into over 20 languages so far:

  • Arabic, Brazilian Portuguese, Bulgarian, Chinese, Czech, Danish, Dutch/Flemish, French, German, Greek, Hungarian, Indonesian, Italian, Polish, Portuguese, Russian, Serbian, Slovak, Spanish, Swedish, Turkish.

Our online tool makes it easy to edit the current translations and create new ones.
