Now - if you tell me that we finally can also save MPRs as dicoms - then I will be happy!
In anycase - great work and it is good to see you developping!!!

I cannot get the addon to show in the application. i have extracted it all to a folder
C:\Program Files\RadiAntViewer64bit\addons

I have a medical practice with several locations and I need to set up something where the patients bring in their Cd from the MRI imaging facility and we can send to a central DB that can be seen by the surgeon on his station. I see I can set Radiant to say a one drive or gdrive location and save to there but i am concerned that it will not handle multiple users at the same time. I see in the beta we can send to a pacs sever. I have started an Orthanc server. However the addon is not showing up for me.

As You can see, Addons must be extracted in "C:\ProgramData\RadiAntViewer\" folder.
Also, You must add some Servers in Servers settings panel.

Nice SendToPACS feature! Excellent 👍👍👍

Just a suggestion to make the IMPORT to PACS more useful.
Can we have a DICOM TAG EDITOR to reconcile the patient ID before sending to the PACS system?

Because different hospitals may have different RN or ID for the same patient.
It is logical to change the patient ID in the CD to match the patient ID in the PACS before import the images to the PACS.

Thanks guys for testing the feature. This add-on solution seems to work pretty well, until at some point we have our own, more powerful DICOM send module.

Great I got it. I needed to add the server first. LOL I have it working internally with Orthanc server. I am going to try and connect 10 other locations and see if it works. Thanks for your help

Nice one!

Anyway I'd see a small expansion of DICOM send feature - I'd like to send the currently open study (or studies) to DICOM destination.

Our workflow requires uploading quite large number of studies to PACS/other nodes daily, and we try not to keep them locally.
Local Storage is great but we don't use it - probably because of the fact it is quite a "recent" feature... or maybe because we've got quite a fast PACS?

Anyway the workflow is:
a) Put a CD in a drive
b) Take a look what's on the CD using Radiant
c) Using more or less obscure methods upload to PACS and/or workstation (windows sendto or that open-source software I forgot the name of, made by a Japaneese)

I'm aware it's a tweak rather then feature extension, but it's quite important one in my opinion. The traditional Radiant approach was "don't keep studies locally, You've got PACS for that", and it'd be consistent with this approach. Moreover I hope to decrease I/O operations from the CD, while sending to multiple destinations...

RadiAnt DICOM Viewer 2021.1 BETA #8830

A few improvements:
-send to PACS from the viewer window
-more compact series selection menu
-PACS search window: fixed searching by dates, F5 refreshes the series list

And regretfully, we are dropping the support for Windows XP/Vista (less than 0.5% active users). Time to move on...

Thank you for Send Pacs future!
I think with this new option Radiant must be able to start as Windows service application. Then for remote computer is enough to turn on, not launching the radiant separately.

I am glad that you stop supporting Windows XP and Vista. Users of these systems are usually not thery good with medical scince. The computers with XP / Vista is also the same on which no scientific PDF books, no radiological sites.
And computers with support for Windows 7 and 10 a long time ago extremely cheap.

Happy Easter to all of You!
Thank you again for the wonderful send-option.
Question: How many Dicom pictures can I store in the local archive? How many patients? I would like to use Radiantviewer as utility to move an old pacs to a new location with 5 million files.
Thank You again.

You are aware that Radiant does NOT support Query-Retrieve as a server?
Apr 3, 2021 11:10 AM
by RadiAnt
I think gpdahmen would like to use RadiAnt to download the studies form the old PACS and upload them to a new PACS (I assume that the direct transfer is not possible for some reasons).

We did not test the DB with 5 million files. But here are the data for a pretty large database:

* 2221 studies
* 934624 files
* 470.7 GB
* the DB file is 188MB
* after loading the DB the RadiAnt process occupies 18MB RAM

So it seems that 5 million files should be handled pretty easily.

Thank you very much, I will report.

I'm afraid someone might believe that Radiant might be used as an actual PACS... Pixmeo advertises OsiriX as PACS ( ) - so why not Radiant? ; ))

We both know why NOT, but once You implement DICOM Q/R server somebody in the world will use it this way.

Fortunately not everywhere amount of data is so huge that currently in my hospital.

One thing is sure, RadiAnt DICOM Q/R server will not happen very soon. Certainly not this year. There are some other priorities.

Hello Rafiant team!

Any plans for GPU acceleration for 3D on Intel or AMD internal GPU in future?

Nvidia GPU prices make pain )))

Looking forward to the curved MPR feature. Hopefully it will be a priority this year!

Radiant is the best as usual, it surpass even famous workstations, however I have a demand and a comment:

Demand: Curved MPR Please, it will be the most important and most useful tool ever, even if it is manual tracing and not automatic it will be perfect and will make us use Radiant in any case ever

Comment: The new trial version mark is very frustrating, I know its your right but what if it can be smaller, It really affects the study interpretation a lot, Hope you consider it please.
Apr 15, 2021 04:35 PM
by RadiAnt
1. No plans for AMD/Intel GPU acceleration for this year unfortunately...
2. Curved MPR is still high on our priority list. Moreover, the engine has been almost finished for some time now. There's still some work to be done as far as the UI is considered.
3. The trial banner has been extensively discussed in this thread:

The "hold shift" to straight line or perfec circle is great.

But if I need to change the position of the line markers or the size of the circle, the "hold shift" will no longer take effect..

ont know if it is intended to be that way, but in think it is better to always enable the "hold shift" while editin existing measures.

Apr 21, 2021 05:09 PM
by RadiAnt
Yes, we're aware of this inconvenience. We will try to improve this during this beta phase.
Apr 22, 2021 02:36 PM
by marcelvn
Good to know.

Other suggestion for practical "hold shift" is in the angle tool. For example: steps of 30 degrees after the base line is traced.
