Smooth MIP`s and 3D and some qestions

Hello, RadiAnt team.

First
You are doing great thing - thank you!

And a question
I am working on old PC, and MIP`s and 3D are making too long.
For example - i`m moving cursor to another place, and the image becomes blur, then I stop cursor and image becomes sharp in a second. How can I make images sharp during moving cursor?
Where is the problem - RAM? CPU? GPU?

And some more questions
Which CPU is better for RadiAnt - more cores/threads (4-6-8) or more single core speed (3-4 Ghz)?
What about new AMD Rizen APU like AMD Ryzen 5 2400G with Vega integrated grafic card (it`s video performance is like GeForce GT1030).
How many RAM needed for comfortable working with 16-slice CT images? 8 Gb? 16 Gb?

And more - can you add MIP-function to main screen (not MPR).
And can I somehow export MPR`s as DICOM?

Thank You!

Lukash, thank you for your kind words!

The lack of CPU (or GPU) power is the reason of image pixelization during interactions in 3D modes. Please have a look at this page: https://www.radiantviewer.com/dicom-viewer-manual/v/4.6.0/gpu-acceleration.htm

RadiAnt can utilize many cores, so the more cores the better. Single core speed is also important, however. For best experience in 3D modes, I would suggest Nvidia GTX 1080Ti card.
8GB RAM should be enough for 16-slice CT studies. But you can't go wrong with 16GB - you will be able to open more studies at the same time.

The MIP function is only available in 3D MPR and 3D VR (4.6.5) windows. This will not change in the near future.

No, MPR cannot be exported as DICOM right now.

Thank you for your reply.
I want to annoy you little more )))

We are talking about workstation for 16-slice CT.
Budget is limited (((

Which CPU will you recommend?
Will RadiAnt work with 6 cores, or 4 will be enough?
Will RadiAnt have significant boost from hyperthreading?
Intel Core i3-8100 (4 cores/4 threads) or AMD Ryzen 5 1400 (4 cores/8 threads)
Intel Core i5-8400 (6 cores/6 threads) or AMD Ryzen 5 1600 (6 cores/12 threads)

Videocard 1050Ti with 4Gb or 1060 with 3Gb?
I know 1060 with 6Gb will be better, but it is significant expensive.
Or maybe i should take cheaper CPU like Ryzen 3 1200 (4 cores/4 threads) but better GPU (1060 6 gb)?

Which pair CPU/GPU will be optional?

You'll be definitely better off with the 1060 3GB card. It should be almost 2x faster than 1050Ti.
As for the CPU, the more cores the better - look at your budget and make a decision. We did not test RadiAnt in HyperThreading/no-HyperThreading scenarios.

Thank you for your reply.

And 1060 6Gb will be much faster than 1060 3Gb too?

No, there should be no difference in speed. You could just open twice as much data using the 6GB version. 3GB should suffice to process 2 large CT studies.

Does Radiant compatible with AMD FirePro? I have got this GPU in my console, and I can not able to switch from CPU to GPU.

RadiAnt only can utilize the power of CUDA enabled NVIDIA GPUs. You will not be able to switch to GPU mode on AMD FirePro, I'm afraid.

Hello, how can I reconstruct the entire ossicular chain and the cochlea in 3d with radiant

I'm afraid that the 3D VR of the middle and inner ear bone structures would be quite difficult (if possible at all) to perform in RadiAnt. There is no way to easily segment this area. You can only rely on the "rough" scalpel.
3D MPR seems to be the only sensible option to visualize the structures you mentioned.
