History of MITK

MITK 1.x: Implemented basic encapsulation of data structures and algorithms, which included most fundamental functions of data handling, filtering, segmentation, registration and visualization.

MITK 2.0: The Out-of-Core mechanism was introduced, which supported the buffering of large datasets.

MITK 2.2: Some reconstruction functions were introduced which formed a new branch of the algorithm hierarchy.

MITK 2.3: The project was reorganized with the CMake tool provided by Kitware. The source code as well as the binaries were divided into multiple modules, which simplified the management, and made it possible that more compiling environments were supported.

Currently, MITK is extending itself in multiple aspects including the support of GPU alogorithms in a more flexible framework.

The zooming of the plane is also improved to keep the change following the movement of the mouse;

    (2) mitkVolumeRendererRayCasting & mitkVolumeRendererRayCastingLoD: Solve the problem that when the pixel spacing is 1.0mm (e.g. 0.001mm) the rendering result is too small to see. This change also affects the member functions GetBounds() and GetCenter() of mitkVolumeModel.

The bug of intermixing rendering with other models is also fixed and the rendering result is improved (note that intermixing rendering is still not perfect now because of the particularity of the volume rendering algorithm).

    (8) A new multi-raw-file reader: mitkRawFilesReader;

    (9) Adjust the design of mitkManipulator's interfaces: move common responding operations of different mouse messages to public functions OnMouseDown/Up/Move(), and place particular operations of derived classes to the protected virtual functions _onMouseDown/Up/Move(). So users who implement their own manipulators which are derived from mitkManipulator must change the name of functions OnMouseDown/Up/Move() to _onMouseDown/Up/Move() and place them in protected functions, if they want to move their derived class to MITK 1.1;

    (10) Fix some bugs found in MITK 1.0;

    (11) Add a complex demo example (Examples/Demo), an enhanced image browser example (Examples/ImageBrowserEx), a enhanced surface reconstruction example(Examples/SurfaceReconEx2) and a simple volume rendering example (Examples/VolRen).
