Imlook4d is a research grade 4-dimensional image browser, with the following capabilities:
It is strong in medical imaging where it can be used for static (3D volumes) as well as dynamic/gated (4D volumes).
What makes imlook4d stand out is its scripting capabilities. Due to its strong integration with the Matlab environment,
it is very easy to integrate menu-driven home-built algorithms, simply by saving a short Matlab m-file in a special folder.

imlook4d capabilities
This is just a brief description of the capabilities of the base imlook4d. Lots and lots of extensions are added in the SCRIPTS menu,
which is the mechanism to add functionality without having to change the base imlook4d software.
- Opening the following file formats: DICOM, ECAT, Hamamatsu SHR, Analyze (experimental), Interfile (experimental)
- Saving to original file format (DICOM, ECAT, Analyze supported)
- Opening data from medical PACS storage.
- Interactive help button
- Easy mouse-wheel scrolling in slice or time dimension.
- Powerful window handling.
- Brush tool for easy VOI (Volume-of-interest) giving activity curves in the 4-th dimension (time)
- Generation of Principal-component images.
- Noise-reducing Hotelling filter (PCA-filter).
- Definition of own colorscales.
- Definition of own preset window levels.
- Export and import to Matlab workspace.
- Export and import to ImageJ, if installed.
- Easy scripting, using Matlab (see below)
- Possible to write interactive image-processing model, for instance instant click-and-see pharmaco-kinetic models.
Extra features:
Workaround for right-click on ROI menu
- On some unix-based computers right-click on ROI dropdown menu does not work
Press [Ctrl] key on keyboard, at same time as right-click on mouse.
Workaround if using old Matlab/Java:
- Blank buttons in DICOM Save dialog
Change to using an external java runtime, by setting the windows environmental variabe MATLAB_JAVA. The value of MATLAB_JAVA reflects the path of a java installation on the computer, for instance C:\Program Files\Java\jre6
Requirements:
Windows, OS X, or Linux with installed Matlab and Java,
and a not too old computer, with at least 2 GB of memory.
Memory requirements depends on number of images in an exam.
OpenGL graphics card may accelerate graphics updates.
