I'd like to talk about how we can have a reader/writer for reading/writing images and their associated history/descriptions.  The history/description of the files could possibly be coded in XML/MRML.

Tutorial Session on ITK (Luis Ibanez)

Topics

  • How do you efficiently integrate VTK and ITK with respect to reading and writing images? Is there one class that can be used to hold data sets for both libraries?
  • How to do FFTs in ITK?
  • What type of coordinate space should be used, voxels vs. real space?
  • What type of image formats should be used?
  • Is there any standard way to read in coefficient files, i.e., algorithm specific parameters?
  • How are XML/MRML files parced in ITK/VTK? We want to know how to use the vtkXMLparser and MRML objects to parse our XML files.
  • What are the memory and performance issues with ITK?
  • How can we debug memory leaks (or force memory collector to start collecting)?
  • How can I access the metadata of each slice in a 3D DICOM volume?
