We would like to take this opportunity to wish you a joyful holiday season and a happy, healthy and prosperous New Year.

Thank you for choosing RadiAnt DICOM Viewer -- we hope to continue to improve it and to introduce many new features in 2014 and beyond!

This time we have a few improvements in version 1.9.10:

• Support for length measurement using estimated radiographic magnification factor (e.g. in mammography images)
• Enhanced PET SUV measurements (e.g. Philips scanners support added).
• Fixed display of certain types of images with VOI LUT.

Download the new version here.

The latest version – 1.9.4 - introduces two new features:

• better support for distance measurements (ultrasound regions, manual length calibration)
• customizable image annotations (currently only via an XML file, which makes this option suitable for the CD/DVD autorun package version)

There are also a few changes to the structure of the CD/DVD version.
And, as usually, a few minor improvements and bug fixes.

Download the new version and check the complete list of changes here.

When we started developing RadiAnt DICOM Viewer we had one goal in mind, to keep it as simple as possible. This is probably why we kept on procrastinating on writing a user manual for our software.

Well, that is, until today. Because today we are presenting you a complete user guide which hopefully will help you get the most out of RadiAnt DICOM Viewer.

The manual is available as a searchable online help or a PDF file for downloading and printing.

Enjoy the reading!

We are happy to announce a new release version of RadiAnt DICOM Viewer - 1.8.6
