A live demonstration of X-ray Computed Tomography (CT) data analysis using ImageJ (an open platform for scientific image analysis). You don’t need any commercial software licenses to enjoy this workshop. We will review the basic operations of ImageJ and analyze CT images. All data sets used in the demonstration are available to the audience. We encourage the participants to download the Fiji distribution of ImageJ and demo data sets and follow the process with us. We will send registrants download links to Fiji installer and datasets before the workshop.
