The Laser Ablation Tomography (LAT) system was developed by the Roots lab, including former student Ben Hall who has created a company focusing on this technique ( L4IS ).

Anatomical traits are measured from LAT images using a number of image analysis programs, including RootScan , a program developed by our lab.

To obtain quality images, it is important to understand the basic concepts of photography. See Photography for Beginners: A Complete Guide and Basic Principles of Photography for helpful information.
