  • Added help topic for the Image calculator utility.
• VOIs
  • Added an option in Help -> MIPAV options to save VOIs in either file coordinates (the old method) or in Left-Posterior-Superior coordinates (the new method).

• Image views & visualization
  • Resolved an error in the Tri-planar view when the Paint grow dialog was closed and the used clicked in the image.
  • Added the option to extend the Tri-planar view crosshairs so that they intersect.

  • Fixed the performance of the Lightbox view.
• Scripting
  • A script action with no images and no VOIs is now handled correctly.
  • When using raw images in a script from the Run script dialog or from the command line, information about the raw file may be specified before it is opened to prevent the Raw image dialog from opening (select multiple images and right click them in the image listing in the Run script dialog; use the '-r "type;xDim,yDim;xRes,yRes;xUnits,yUnits;endianess;offset"'... option from the command line).
  • Fixed the scripting of the Invert utility.
  • More image attribute changes are now scriptable:
    • Endianess
    • Modality
• Miscellaneous
  • Changed the handling of image matrices within MIPAV.

  • Fixed painting so that it follows the user's cursor as expected when approaching the border of a pixel.
  • The Screen capture utility now adds '_screenCapture' to the name of the original image when naming the generated image and keeps the dialog open after each capture to facilitate capturing multiple windows.

  • Performing a Quick LUT will now update the Histo/LUT dialog immediately if the dialog is visible.
  • Fixed the Otsu and Maximum entropy thresholds.

3.0.1 (11/22/2006)

• File handling
  • Fixed 'Save image' for XML images (was saving to imagename.xml.raw).

  • The Save DICOM dialog now sets the modality chooser (for DICOM tag 0008,0060) based on the image's modality.
