news about development?

I was just curious to know how things are going about the development of next release...

could you please give us a preview list of new features and/or bugfixes?

as I have already mentioned, next major feature will be MPRs. It could be still about a month before we release it, however. We also plan to implement a crash reporter module in the (hopefully rare) event of bugs causing RadiAnt crashes - we strive for top quality :-)

in case you need beta-testers for the new MPR feature you can count on me

Your help will be much appreciated :-) I'll let you know the moment we have a working beta.

how's going the MPR development?
will a working beta be ready in the next weeks?

We prefer to get things done right, even if it takes a bit longer than predicted. Perhaps in two weeks a beta version will be ready. Thanks for your patience! :-)

Here's a quick video preview of MPR feature:

Thanks! I guess in about two weeks we'll be ready to release a beta version.

Just a quick update - MPR (coronal, sagittal) works quite well, however, there are a few glitches that we wouldn't like to be present even in a beta release, so the end of November is the new deadline.

what about MPR from coronal or sagittal source images?

as I pointed out in previous posts, many MPR softwares I tried have troubles with correct orientation when dealing with non-axial source images...

MPR from axial CT images are usually well reconstructed in coronal and sagittal

whilst MPR from sagittal (or coronal) MR, usually generate weird axials (i mean upside-down axials, like the patient was prone...)

if you need it I can provide some anonymized samples DICOM files from my MR magnet... we do a lot of isotropic 1mm thickness SPACE T2 sequences of the spine...

we acquire them in sagittal, then we reconstruct axials and coronals
I'm very curious to know if Radiant MPR can handle correctly these files

Tommy, your help is much appreciated! It would be nice if you could share your sample sequences for testing :-)

At this stage RadiAnt can only make coronal and sagittal from axial slices but I guess this won't be a big deal to add the functionality you're talking about.

one case is a SPACE T2 sagittal sequence of the lumbar spine.
images are 1mm isotropic.

the other is a TrueFISP T2 WaterExcitation coronal sequence of the knee. images are 0.8 isotropic.

both sequences were acquired on a Siemens 1.5 Tesla magnet.

ideally the coronal and axial MPR from the sagital source
and the sagittal and axial MPR from the coronal source
should be oriented in conventional fashion

as I said before, some MPR softwares have troubles with those dataset showing weird orientation of MPR (i.e. upside down axials or inverted left-right coronals)

does Radiant beta do the same?

I've seen the video preview that you sent me by mail.

the handling of MRP from sagittal or coronal source images looks perfect!!

the orientation is accurate either up&down and right&left

thumbs up!!!

Happy to hear you liked it :-)

Just wondered if there is an option to thicken up slices &/or use MIPS !

Eager for the release

I wish there was a MIP option along with MPRs... But we'll have to wait a few more weeks.

MPR will be a major step
MIP will be the cherry on top of the cake

however I'll prefer having MPR as soon as possible and wait forMIP in a subsequent release.

Absolutely, mpr will be a giant leap forward, MIPS n 3d once onboard, we are then in a different league head on with osirix !
