Slice viewers can be used to specify oblique reformats using the 'Reformat' orientation (instead of axial, coronal, sagittal) and CTRL-Right-Button-Move
(subject to change).

A new label map smoothing tool has been added to help with our collaboration with Children's Hospital Boston, SCI at University of Utah and Northeastern University. The unfiltered labelmap is shown in blue, and the filtered results are shown in peach.

Clipping with the slice plane is now supported, along with thresholded image display.

The FreeSurfer colour lookup table has been added to the Slicer3 FreeSurfer Library. A curvature overlay file was loaded and displayed on bert/surf/lh.pial as loaded in via the Models module.

The FreeSurfer scalar reader has been integrated as a Slicer 3 Library, and surfaces can be read via the Models module. Shot shows standard bert/surf/lh.pial plus a test script to load the annotation labels file.

Test of making a non-orthogonal slice plane. This was created by manually setting the SliceToRAS matrix in the vtkMRMLSliceNode. GUI is not yet hooked up for oblique slices.

Shows that a single pixel voxel in black is exactly bounded by a unit cube in RAS space. Also the blinking eye buttons for slice visiblility are hooked up and there is now a red-yellow-green color coding for the slice windows (carried over from slicer2).

Test of the new logo widget for adding module-specific watermark logos directly in the 3d view. Uses a vtkLogoWidget from VTK cvs head. Kitware is working on cmake support to notify developers when a VTK cvs update is needed. Once that is done, the logo code will be added to slicer3 svn.

A number of things have come together to allow the new prototype editor module:
- the label map layers are enabled
- lookup table support in the layer logic
- a new set of 2D UI widgets
- generalized painting infrastructure, which is based on requests and feedback from NA-MIC Core 3 users and other users of Slicer2
- paint brush has a 'threshold' option in which the label map only gets painted if the background intensity is in a specified range
- paint brush optionally won't overpaint existing voxels
- 'eye dropper' mode allows you to start painting with the label value where you first clicked (so you don't need to go to the UI to change the label color as often).
- all painting operations can happen on arbitrarily transformed volumes. This allows the painting plane to be aligned with the major axis of a structure like the hippocampus
- background layers are interpolated to current screen resolution (not limited to nearest neighbor sampling as in slicer2's draw mode)
- painting is performed using a circular brush with a diameter selected by the user. this makes it easier to follow the contours of curved biological structures.
- the cursor is turned off on mouse down and reappears on mouse up so you can see the exact pixels you are drawing (a circle around the cursor location indicates the mouse location)
A few limitations make this still a 'prototype' including:
- there's no convenient way to save your label maps volumes (except as dicom)
- the color map is currently random
- only label numbers 0-255 will show as distinct colors
- no hot keys for frequently used operations
- brush radius is in screen space units rather than RAS (means that the brush is effectively getting bigger and smaller as you zoom in and out)
- the paint algorithm is implemented inefficiently and can be slow when painting large numbers of pixels
- much of the code is written in tcl - new vtk classes are needed to implement the functionality more efficiently.

Test of interactive slice textured plane control. Not yet eneabled through GUI, but driven by a test script that you can source into the console.
Type Control-T to bring up interactor, then
source Base/GUI/Testing/TestSliceModels.tcl SliceModelsAdd
This test does things the right way in that it creates model nodes for the slices and the updates of the planes is triggered by observers on the Slice Logic. But it does things the wrong way in that it creates the texture in an ad hoc way for now since we don't yet have a clean way to specify textures in the model display nodes. Also, the Viewer renders on every changes to the slice view, so as you pan/zoom/scroll the slices the redraws are jerky. Next step is to figure out how best to get this functionality integrated into the C++. Probably there should be a vtkSlicerSliceModelsLogic class that's managed by the vtkSlicerSliceGUI.

Now, do something interesting with it!
>>> # import MatPlotLib via pylab functions so we can refer to them directly >>> from pylab import * >>> imshow ( data[128,:,:] ) >>> # Instruct pylab to show our plots... hit return to continue entering commands. >>> show()
About the VisualBlog
The VisualBlog is meant to be an easy place to upload screenshot so that both developers and outside observes can track the progress of the project.
Plans
We're looking into adding the wikimage command as menu item in slicer to further simplify, but for now it can be run on the command line.
Every month or so we can copy the contents of the page to an archive location so this page doesn't get too long.
