The 4D Analysis Module allows you to analyze a time-series of 3D images (4D image) on [http://www.slicer.org/ 3D Slicer]. Currently, the module offers the following functions:
−
*'''4D image loader.''' The module can load up a series of 3D images from a specified directory. It analyzes DICOM header of the files in the directory and split them into time-frames, even if all frames have the same series number (some MRI scanners generates time-series images without incrementing series number, resulting a large number (typically several thousands) of 2D image files output in a single directory). The module can also read a directory, which contains NRRD files.
+
*'''Intensity plot.''' The module can draw intensity curves at the specified regions of interest.
−
*'''Time scroll.''' The module provides a scroll-bar interface to scroll the frame in time-direction. It allows you to scroll the frame for foreground and background screens independently to compare two images at the different time points.
+
*'''Pharmacokinetic model analysis.''' The users can perform pharmacokinetic model analysis based on the intensity curves. Models are defined in Python scripts so that the users can modify the existing models or create their own pharmacokinetic models.

+
*'''Parameter map.''' The module also allows generating a map of pharmacokinetic parameters.
−
*'''Series registration.''' The module provides a user-interface to perform image registration for each frame with a key frame. This function is useful if you want to perform intensity curve analysis on a series of images of an organ moving through the frames.

Module Description

The 4D Analysis Module allows you to analyze a time-series of 3D images (4D image) on 3D Slicer. Currently, the module offers the following functions:

  • Intensity plot. The module can draw intensity curves at the specified regions of interest.
  • Pharmacokinetic model analysis. The users can perform pharmacokinetic model analysis based on the intensity curves. Models are defined in Python scripts so that the users can modify the existing models or create their own pharmacokinetic models.
  • Parameter map. The module also allows generating a map of pharmacokinetic parameters.

Development

Installation

Although the module's source directory is in the trunk repository, it is not included in the CMake configuration. To use 4D Analysis Module, you need edit Slicer3/Modules/CMakeLists.txt and build the module.

(Supposing you have your local copy of 3D SLicer under <working directory>, in the following instruction)

1. Edit Slicer3/Modules/CMakeLists.txt

In subdirs section, insert 'FourDAnalysis' as: 

subdirs(
  MRIBiasFieldCorrection
  
  ...
  
  FastMarchingSegmentation
  FourDImage
  FourDAnalysis                                # <- Here!!
  ExtractSubvolumeROI
  
  ...
  )

2. Build the module

In Linux or Mac OS X, 

cd <working directory>/Slicer3-build/Modules
make

In Windows, open the project file in <working directory>/Slicer3-build/Modules, and build all.

3. Check the module

If the module has been built successfully, it shows up in the '4D' section in the module selection list.


Dependencies

The intensity curve analysis functions depend on SciPy package. Please turn on SciPy option when you build your 3D Slicer.

Known bugs

Follow this link to the Slicer3 bug tracker.


Usability issues

Follow this link to the Slicer3 bug tracker. Please select the usability issue category when browsing or contributing.

Source code & documentation

Customize following links for your module.

Links to documentation generated by doxygen.

More Information

2D Graph

The module provides a set of classes to support 2D Graph for intensity curve plotting, which can potentially be used for other projects. Please refer Slicer3:2DPlotting for more detail.
