CoreTOM, DynaTOM, and UniTOM XL systems are leading-edge micro-CT systems from TESCAN that facilitate image acquisition, 3D reconstruction, 3D visualization, and quantification. Micro-CT systems can reveal structural changes over time as a function of changing variables. These instruments are designed for high throughput and flexibility, they offer novel dynamic CT workflows for which the user will be able to access a wide range of 4D applications in areas from Earth Science to Materials Science and beyond.
