Module Description

The 4D Image module is designed to handle a time-series of 3D volume images (4D image), e.g. fMRI, cardiac images, dynamic contrast-enhanced (DCE) images in 3D Slicer. You can do:

• Load and save a series of 3D volume images from a directory, which contains multiple volume images.
• Scroll through a time-series.
• Edit (add, delete and insert) frames in a time series.

The core component of 4D Image module is time series bundle node, which is defined as a vtkMRMLScalarVolumeNode class. This special MRML node is designed to hold pointers to scalar volume nodes in the time series, and in addition, two scalar volume nodes for visualization. The two visualization scalar nodes contains byte arrays that are displayed in the 2D and 3D viewers; whenever the user scrolls the time-series, the module copies byte arrays from the scalar volume node at the current time point in the series to the nodes for visualization. This approach gives a flexibility to use the existing frame works of image processing for each scalar volume nodes in the time-series data. The reason why it holds two visualization scalar nodes is that one is used for background and the other is used for foreground for comparing two volumes at different time points.
