  • Fixed issue with ellipse ROI calculations in fusion MPR (coronal and sagittal) images.
  • Faster DICOM load and export times.

RadiAnt DICOM Viewer 1.1.3 BETA
by RadiAnt on August 16, 2012
This version features better support for the new enhanced multi-frame DICOM CT and MR files - measurements, default window parameters, auto synchronization, cross reference lines, MPR and fusion should now work properly.

We also improved significantly performance of a 32-bit version while reading and exporting large number of DICOM files (an export performed on our >100000 files database was 5 times faster than in 1.0.4 version).

One small addition is SD calculation in ellipse ROI.

RadiAnt DICOM Viewer ready for Windows 8!
by RadiAnt on August 10, 2012
With Windows 8 just around the corner, we have been testing our viewer using Windows 8 Release Preview version and can confirm that RadiAnt DICOM Viewer is fully compatible with the new operating system from Microsoft arriving in October.

Once Windows 8 tablets are available to customers, we will update RadiAnt DICOM Viewer to fully utilize multi-touch gestures. Only tablets with Intel CPUs (Microsoft Surface Pro, Lenovo ThinkPad Tablet 2, etc.) will be supported because RadiAnt is a Desktop Application and cannot run on ARM devices.
