3D Cursor in RadiAnt DICOM Viewer 4.5.8 BETA

The wait is over. This small but highly desirable feature is now available in the latest beta version.

Just press Ctrl + Shift + Left mouse button and move the crosshair cursor in one viewport to synchronize its 3D position in other viewports. If the cursor is in some distance away from the plane it is displayed in red color.

It works just as planned! It`s great! Thank you.

We have another small update - version 4.5.9

You can now choose the 3D cursor tool from the "Measurements and tools" menu on the toolbar. Or use 'Q' key to select it.

All basic tools can now be assigned to different key modifier + mouse configurations. Just select "Customize keyboard" from the "Help" menu and type "Mouse" to display all possible mouse button/tool pairs. You can assign Ctrl, Alt, Shift or their combinations to the specific mouse button/tool. So for example you could make RadiAnt draw Length using Ctrl + Right mouse button and draw Ellipse using Shift + Right mouse button.

I remapped the cursor from the "Q" key to the "Alt" key
if works at first try, then if you change tool (i.e. "L" for line measures) then you click back the "Alt" key it doesn't activate the 3D cursor again.

'Q' key is mapped to the permanent selection of 3D cursor.
You need to remap the Ctrl+Shift shortcut ("MouseModifiers.LeftButton.3DCursor" command).

It is so great to see Radiant (the most effective DICOM viewer in my eyes) now has this feature. There is no word to express my gratefulness.

By the way it works smooth.

the 3D cursor was a major improvement, indeed.

so, what's next? :-)

Tommy, we have one in mind - a local database of studies.

A local database will be great. It opens expectations to come with a DICOM listener function, should we hope for it?

I would like to see a customizeble print layout for images, any chances?

Sure, you will be able to push DICOM studies from servers/modalities to RadiAnt when the local archive is ready.
Currently no printing features are planned in the near future.

Great feature.. even the famous DICOM viewer from OSX doesn't have this feature (it only allows it on MPR viewer).

I love RadiAnt! A local database of studies must be the next step please!
And let me dream of other features like...
- Spine Labeling
- Synchronise 3D MPR,
- Synchronise the window behavior (When im comparing 2 studies, once you click on "sync window" and you switch to the next series and both studies change to the next series).
- Allow to collapse the thumbnails if a patient has many studies.
- Add a sidebar where the measurements that you do are saved and than simply clic on the sidebar to see where the meassurment was made (idealy por pulmonary nodules).

@Perebre MD

Thank you for your kind words and suggestions!
In fact, a local database is in the works right now.

Is it possible to load two studies in the same window using the command line arguments? I am looking to open chest films of dogs for comparison. Same patient. Different dates.

I found a bug relative the the "3D cursor" hotkey customization.

I wanted to assign the "Alt" key to that function but hitting the alt key has no effect... it doesn't activate the 3D cursor... you have to enable it using the toolbar menu.

instead other regular keys do work.

basically even if the "Alt" key is assigned to that function, it won't work.

tested on 2 different PC (one running Win7x64 and the other Win8.1x64)

this is important to me since I want to exactly match in RadiAnt the same hotkeys I have in iQ-VIEW where the ALT key activates it's 3D cursor,

Tommy, you have to assign the Alt key to the "MouseModifiers.LeftButton.3DCursor" function.
Then, you press Alt and use left mouse button to operate the 3D Cursor.

fixed. It was my fault. I was trying to assign it to the ViewerWnd.Select3DCursorTool that's why it did not work

I could not found
- 3D Cursor in MPR mode
- HU field measurement tool
So please tell me how to use these tools

The functionality of "3D cursor" in 3D MPR mode is actually provided by the axes that you can drag - their intersections always show the same point in 3D space.

HU measurement tool is not yet available in 3D MPR mode.
