RadiAnt DICOM Viewer 3.9.39 Beta

RadiAnt DICOM Viewer 3.9.39 Beta
built on April 9, 2017

New features:
* Touch support in 3D MPR window: one finger - current left mouse button tool, two fingers - pan, zoom & roll, three fingers - window adjustment, four fingers - thickness adjustment.

Improvements and bug fixes:
* More keyboard shortcuts in 3D MPR window: pan (Ctrl + arrows), zoom (Ctrl + +/-), roll (left/right), 3d rotation (Alt + arrows), full screen (F).
* Display WL/WW values in lower left corner.

That's right. It's closer than ever ;-)

I have an HP elitebook 840G3, with a sypaptics touchpad, recognized in windows 10 as a precision touchpad. The touchpad two finger scrolling in windows 10 is great and smooth. In Radiant the browse function with two fingers only responds is imprecise and only responds to quick and strong swypes.

Any chance to give a look at that?

Thanks again for the great MPR feature. Maybe just one thing: when we use 3D rotate tool in MIP, the rotation is not connected with the main slab axes position, so can you implement the axes-lock feature or something like that to have an opportunity to rotate MIP reconstruction with different slab thickness as 3D object?

The 3D MPR viewer currently is designed in a way that the viewing plane is always parallel to the thick slab.
It would be much easier to implement the feature you asked about in the 3D VR window (via rendering mode switch VR/MIP/MinIP/Avg). And this is what we'll probably do.

I have tested the beta version of your viewer. As a nuclear medicine physician I am used to view MIP of PET studies. It takes some time to produce such images in RadiAnt viewer- commercial software packages delivered with cameras usually produce this type of images as a "business standard", without the necessity of manual slice thickness setting.
The blurring of images (slow redrawing) during 3D rotation (rolling) in RadiAnt is very uncomfortable as we usually use this way of review to observe pathologic structures from different angles, can this be improved?
When browsing conventional nuclear medicine studies (e.g. bone scan), is there a possibility to adjust the lower threshold of activity? It seemed to me, that only the upper threshold can be adjusted.
Anyway after review of a couple of DICOM viewers available on the internet I have to admit, that RadiAnt is the closest to my idea of such application for occasional private work and if the issues mentioned above could be solved I would definitely consider buying the license.

Hi David,

We will implement the MIP rendering mode in the current 3D VR viewer - no manual thickening will be necessary.
As for the speed of rendering, it will be much faster when GPU accelaration is available (provided that you have a decent CUDA enabled Nvidia card).
Currently the lower activity threshold is fixed at 0 for NM studies. The option to change both thresholds will be added.

Kind regards,

In consideration of the problem moved by David about the speed of rendering, how can i enable GPU acceleration?

You can't yet. There is no GPU acceleration support implemented yet.
