Color Lookup Tables

Are you planning to add support to color lookup tables?

other viewers like Sante Viewer and K-PACS have it and is quite useful in nuclear medicine studies (scintigraphy and PET) and MRI as well (I think about watching color maps of breast studies or body DWI)

There are some things more important but yes, we plan to add this feature, too.

after watching the PET-CT fusion preview I wonder if you have implemented support for color lookup tables

That's right. PET-CT fusion couldn't be done without color lookup tables. However, right now they're only used to draw overlayed semitransparent images. Later we'll add CLUT selection in "normal" images.

feature added in beta 1.3.9

- Change color scale in fusion images (click color bar)
- Change fused image opacity (left mouse button down and drag over color bar)

well done, as usual!!!

hi, is it possible to use color lookup tables even on non-fused images?
actually you can apply them only in fusion
it would be nice to have them available as an alternative to gray-scale in normal images

I'm afraid there is no other way than fusion to apply CLUT... This feature will be enhanced most probably next year. Also, now you can only use a linear table, we will add other types (logarithmic, etc.)

I call this "fixed". Now multiple color schemes have been added.

It's 2018, can color lookup tables be used on non-fused images?

what would be the purpose of it? nuclear medicine studies?

I've just figured out that I personally made this request in 2011...

Yes, Tommy you did ask that question in 2011 and I re-asked it in 2018 to confirm that it was made. The purpose would be research. I've opted to use MRIcroGL instead BUT might consider reverting to use RADIant if the functions I need are available

We try to prioritize features based on the potential user base for certain functionality. Yet, the color look-up tables will be added for sure at some point.
