8. A 3D scanner is used to create a 3-dimensional image of an object. The scanned 3D image is then worked upon to improve many of our favourite and widely used products.
9. MRI Scanners and CT scanners play a vital role in the healthcare sector, diagnosing many fatal diseases in their early stages.
