I agree that this is an interesting topic.
I belong to the minority too, as I use ImageJ within the field of materials science; more specific the study of electrodes and raw materials used for light metal production. I use ImageJ to visualize and quantify porosity, measure gradients and grain-sizes, failure analysis, etc. In the past I used optical microscopy for the imaging, but I now mostly use micro X-ray CT as the benefits of examining the entire 3D sample in a non-destructive way, by far outweighs the disadvantage of the poor spatial resolution. I usually work with a 5-20 µm voxel size which is sufficient to image the cm-sized structures of the materials.
I don't think the heavy connection between ImageJ and biological sciences matters much, especially when using ImageJ 1.x. Most of the functions there are of a general nature and will work with any type of image data. I very rarely use Fiji, as the many plugins there are focused on biosciences and rarely useful in a materials context. The main exception is BoneJ, which is excellent for analyzing all kinds of connected porous networks. I have also found VolumeJ and TransformJ to be very useful for general handling of 3D data. All these three plugins work fine in ImageJ 1.x too.
The main reason I prefer to use ImageJ over commercial tools like Avizo and Volume Graphics is its simplicity, speed, and flexibility. It only takes a second or two to open the up to 64 GB datasets I get from the µCT data reconstructions, using virtual stack. All the necessary calibrations are taken care of by a macro that interprets the metadata provided by the µCT software. I usually also recommend ImageJ to students who work on our projects, and see that they use a very short time to get started with it, as ImageJ is kind of self-explanatory via its menu structure.

Hi Catherine, and everyone,
I have wondered the same - and not found any numbers anywhere.
I am in a distinct minority, being a metallurgist using IJ for following the precipitation, growth and dissolution of precipitate particles in steel. A particular issue is that we have several species simultaneously present, of distinct (and very different) sizes, shapes, and locations within the microstructure. Selecting imaging conditions that allow sensible resolution and quantification is a challenge.
Various uses of IJ have been published in the metallurgical literature, but often they are characterized by an uniformed approach - using jpeg file format is a common source of error.
There is anecdotal evidence of a reluctance amongst fellow materials scientists to engage with (and benefit from) this list as the world of life-sciences is seen as 'too different' from ours. Yes, there are differences, but much that can be adapted and learned from.
Best wishes!

Does anyone know the statistics on the usage of ImageJ? All I get when I search for the statistics on the usage is country by country stats.
Thank you!
