Portable RadiAnt viewer

I'd like to have a portable RadiAnt viewer to keep in my USB drive in order to watch DICOM files in computers where RadiAnt is not installed

I've seen that there's an USB release here:

but it seems more intended as an autorun software for CDs or USB drives already containing DICOM files.

simply copy radiant to usb drive. important: put the license- file from C:\documents and settings\All Users\App data\RadiantViewer to the radiant directory

works fine!

C:\documents and settings\All Users\App data\RadiantViewer ?

I don't have such a folder.... (Vista 64 bit)

OK. I solved.
By the way I think it would be much better to change the licence.dat file inside the installation folder as well...
so people could easily move their RadiAnt viewer wherever they want.

sorry, forgot to sign the previous post.

I meant: "it would be much better to change the licence.dat file position inside the installation folder as well..."

you should think about people working on computers where software installation has been disabled by system adminstrators.

RadiAnt Portable would be a bless for them

RadiAnt can be installed even by the user without administrative rights (Documents and Settings\USERNAME\Application Data\RadiAntViewer32bit folder will be chosen automatically). Anyway, I'll think about portable version.

a friend of mine working in a Swiss hospital told me he couldn't install RadiAn because of system administration restrictions

Ok. It works on Windows XP but Vista and 7 still require administrative rights... I'll look into it.

my suggestion, is to change the licence path into RadiAnt installation folder... in this way, installed version would became fully and easily portable.

USB portability is now an added value that users enjoy a lot

is the "portability issue" going to be addressed in 0.70?

I know... you told me that before...
I was talking about changing the location of the licence in order to make RadiAnt natively portable without user interaction

No, in our opinion it's not that important an issue. We'll think later how to deal with it. And for very determined ones there's a solution presented by Jens ;-)

Ok. I'll do the manual way...
it's an easy hack :-)

How can I put in the licence information ?

We officially support only Publication License to run without installation, but it's purpose is to open patient study recorded on the cd/dvd media. The standard version of RadiAnt has to be installed on the system it is being used under.

Hi, I use RadiAnt most as portable version. It works until it wants a new licence-file. So I have to trash my CD/DVD and create it new; background: most of my doctors are not as modern as they should be. I have to put more than one picture results, which I want to group on DVD for the medical round. But if the licence wants to get renewed, I have to create this DVD new.
Any solution? Because; if RadiAnt nags on my home-PC, which is connected to internet, it gets a new licence and ok. So - why a licence?

I suggest to buy a licence as I did.
it's cheap and the software is great
so the money are well spent

Actually RadiAnt DICOM Viewer is not meant to be portable.
For the purpose of distribution on the optical media we have the RadiAnt DICOM Viewer CD/DVD version. This version doesn't have the auto renewal of the evaluation license, as it is for testing purposes only. You need to purchase the RadiAnt DICOM Viewer CD/DVD license to legally record our viewer on the optical disks.
You ask "why a license?". Medixant is a for-profit company, we have to earn a living somehow...

We can install a portable version of Radiant.

Here is a guide:

Hope that helps :)

I wanna ad d that buying a CD/DVD RadiAnt license is worth it for your business.

since we changed our CD default DICOM viewer from the Siemens syngo FastView to RadiAnt, we had very positive feedback from patients and from referring physicians.

the intuitive interface of RadiAnt and the great loading speed of the DICOM images impressed a lot of them and made easier and more comfortable to review our exhaminations.

Thanks, Tommy.
There will be one exciting addition to the next version of the CD/DVD viewer. It will support encrypted DICOM studies (using a very safe AES-256 algorithm). The study will only load when a correct password is entered in RadiAnt.
