Objective
Implement a set of 3D Slicer modules to handle 4D images in 3D Slicer for perfusion analysis, cardiac, etc. including:
- Loading 4D image. We will implement a feature that allows the user to load a series of 3D images from a specified director. The data can be either in DICOM or NRRD format.
- Time line. We will develop 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.
- Motion compensation. We will develop a method to compensate organ motion (respiratory motion, cardiac motion etc.)
- Intensity plot. We will implement an interface to plot temporal changes of intensities at specified regions. This feature is useful for analyzing dynamic contrast images.
- Model fitting. The module provides a python interface to analyze intensity curves obtained from the 4D images. The interface will be used to fit pharmacokinetic models to intensity curves to obtain perfusion parameters.
