Module Description

The 4D Analysis Module allows you to load, visualize and analyze a time-series of 3D images (4D image) on 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.
• 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.
• Intensity plot. The module can draw intensity curve at the specified region of interest.
• 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.
