I’ve used 3D slicer for generating 3D models. I’ve used the wacom stylus and tablet for drawing the segments. Wacom has a tablet where you can draw directly on the screen, which I think would be really useful in the segmentation process, especially for students with no drawing experience, it would provide more control. Obviously, the threshold tool is extremely useful, but having more control when drawing is always helpful.
Segment editor works well on Windows computers with stylus (and Surface Dial, etc.). You can draw directly on the screen on all Windows touch-enabled PCs and modern stylii are fast, highly sensitive and support tilting. Do you still need Wacom pen? Does Wacom pen work differently?
I use a medium-sized wacom tablet/stylus (Wacom Intuos PTH-651) with a Mac laptop to do segmentations and it works great. I’ve customized pen buttons and tablet buttons for specific functions so I can quickly switch between paint and island removal (for example) to do segmentations. When you switch between functions a few hundred times a day, saving even a couple of seconds per operation adds up.
I’d be curious to hear about what workflow ideas others have for segmentations.
Have you seen the Wacom Cintiq? I was wondering if you could use 3D slicer on it… I
I’m working on a medical imaging elective and I want the students without an “artistic” background as much control as possible. Because i’m in medical library, I need a drawing system that interfaces with PC and MaC, but I like the idea of using a touch screen…
I’m working on models that can be presented in parts.
Also note there are a number of keyboard shortcuts that you can use in Segment Editor: http://slicer.readthedocs.io/en/latest/user_guide/module_segmenteditor.html
For example, a very effective shortcut is
space key, which switches between last two effects (for example: paint/erase) or activates/deactivates an effect (for example: activate scissors/deactivate scissors so you can rotate the 3D view).
Let me know if you have any other suggestion for additional keyboard shortcuts that would make your workflow more efficient.
Sorry for the very slow reply. I use the space key shortcut constantly.
I was wondering if there’s a way to make the “Editable intensity range” checkbox a shortcut key. I turn it on and off all the time for efficiency - for brush erase and island removal, it runs noticeably faster when Editable intensity range is unchecked (one less compare per voxel adds up).
Any thoughts? I’m sure that adding shortcut keys can rapidly turn into feature creep, with everyone wanting shortcut keys for anything and everything.
Thanks for the feedback. I’ve added a shortcut for toggling masking by master volume intensity by
i key. It’ll be available in Thursday’s nightly build.
Wow, this works GREAT!
I use a left-handed 3 button programmable mouse and a Wacom Intuos tablet. I’ve set up one pen button to select sphere brush and turn on Editable intensity range and a second to select remove islands and turn off Editable intensity range. This allows me to basically do all my editing functions with minimal mouse movement and I never have to reach for the keyboard (“HOTAS, or Hands On Throttle And Stick”, as they say in the aviation world - I have my mouse buttons customized for other functions to speed up workflow.)
This probably just saved me a couple of hours per week in just mouse movement and computation time (island removal with editable intensity range off is a lot faster than with it on).
Thanks again! You guys are awesome!
Zoom and rotation are possible on 3D view, and I will display sliders or arrow buttons to let the user translate the view.
To inform other users, I am using a XP-Pen Artist 12 drawing tablet with screen and Slicers is running perfectly, including volume rendering.
What do you mean? Display where?
Using shift key, you should be able to translate the view.
Does the tablet has programmable keys? If yes, then you can configure keyboard shortcuts for translating views.
xp-pen artist 12 display tablet has 6 programmable keys and I touch bar . 11.6 inch IPS Screen . 8192 levels of pen pressure . 5080LPI
Could you share a video with Slicer running on the tablet ? This would be very informative.
