Imlook4d started as a viewer for 4-dimensional viewer for medical PET, CT, MRI images, but has for more than a decade evolved to include tools typically not available. The most important feature is the easy method to extend functionality by adding a single matlab file into a folder (resulting in it becoming an integrated menu in imlook4d)
Figure: imlook4d PET/MRI with applied temporal Hotelling filter
Easy method: Download from the imlook4d web site (https://sites.google.com/site/imlook4d)
Advanced user: Clone this repository
The program is developed in Matlab
Some features of imlook4d:
-
Full 4D VOI analysis, using brush tool (easier than polygons), and thresholded brushing.
-
DICOM, Nifti, Analyze, ECAT (very fast compared to Matlabs routines), and reads binary, interfile and some other formats
-
Export/Import to Matlab, gives full access to data in Matlab workspace
-
Drop-in SCRIPTS makes it easy to add matlab code to imlook4d menues
-
Some 30 useful scripts for Matrix and ROI manipulations
-
Support for ImageJ and SPM
-
Interactive help, click on the GUI or menu, and a detailed help opens
Requirements: Windows, Linux or MacOS, and Matlab with no extra toolboxes
