Otsu Thresholding Segmentation with the 3D ROI Tool

Since its introduction in 2010, the 3D region-of-interest (ROI) operator has aided our users in quantification and volume estimation from their image data.  The prerequisite of any quantification or volume estimation task is an accurate segmentation for the volume of interest.  The 3D ROI tool’s combination of manual, semi-automated, and fully-automated segmentation routines provides a highly complete toolbox with an emphasis on accuracy and efficiency for the user.

iPACS reporting: Generating PowerPoint Presentations

After a VivoScript has been run, it is often useful to organize its output in a single document that can be used for a quality control check or to present the results. This is especially helpful in compiling many results into one document–reporting tools can loop through a study with hundreds of datasets and compile their relevant results into a single document, saving you a lot of time. You may be familiar with VivoScript reporting tools that create PDF presentations or XLS spreadsheets, but did you know you can also generate Microsoft PowerPoint Presentations from VivoScript? Keep reading for an overview of how it works and a few examples of cool features that give you a lot of freedom to control formatting, hyperlinks, and more in the resulting presentations.

Introduction to VivoScript – Part III: Automated Segmentation

Histogram based auto-thresholding (based on Otsu’s algorithm) is a great way to automatically segment two Gaussian distributions of values, e.g. background vs. animal. In this post we are looking into automating this process and placing the segmentation function into a library file so it can be reused in other scripts.
