For Education

The last few decades have seen rapid growth in the use of X-Ray Computed Tomography (CT) in health care. Widespread use and rapid innovation in CT have contributed to the need for improved training for physicists and related health care professionals.

The physical principles of CT are difficult to demonstrate in a teaching environment. Most CT scanners are dedicated medical systems in regular clinical use – this limits access for education. Furthermore, the use of X-Rays and the complexity of controls on medical CT scanners limit the ability of students to interact with the scanner and to investigate relationships between acquisition and reconstruction parameters and the resultant CT image.

The Vista Cone Beam Optical CT Scanner for Education is designed specifically for teaching computed tomography in the classroom. It invokes the same physical principles as X-Ray CT imaging using light photons instead of X-Ray photons. The scanner also comes with several laboratory guides that have been developed for student experiments to demonstrate medical imaging physics.

The Vista Cone Beam Optical CT Scanner for Education is ideal for demonstrating the following principles in a classroom setting:

Acquisition – projection images (analogous to digital radiography) of a translucent object, detector characteristics, multiple projection angles for CT, fan and cone angles

Image Review – pre-treatment of images for CT reconstruction, filtering, sinograms, corrections for scattering

Reconstruction – Feldkemp back projection, image resolution and voxel dimensions,
data management

3D Image – interact with the constructed image, artefacts, dynamic range
