Changes from Stradwin 4.6 to 4.7
Surfaces can now be independently updated from their respective contours, which allows for the use of different resolutions, smoothing parameters etc., in each surface.
Added a more sophisticated surface smoothing setting which will not shrink the surface even when significant smoothing is applied.
The femur segmentation task has been improved, with the model now registering closer to the thresholded points.
The 'find' button in the draw task now centres the 3D window as well as locating the 2D windows, for easier visualisation of specific surfaces.
There is now a greater range of possible surface resolutions.
Added an additional QCT phantom (the Image Analysis Solid HA phantom).
Speeded up loading of large DICOM data sets when stored in a single file.
Corrected a data wrapping issue in display when using very narrow windows.
Added support for greyscale data stored as RGB jpeg images in DICOM format.
Cortical thickness measurement
It is now possible to create a new surface from the thickness estimates which defines the inner and outer edges of the cortex and is intelligently smoothed making use of local consistency to remove outliers.
All surface colour map scales now have adjustable maxima.
Thickness estimation is now slightly faster.
When averaging data over a surface (with the line thickness setting), averaging is now performed over a disc-shaped surface region, and the outer cortical surface is aligned before the data is averaged.
