Multi-slice Optical CT Scanner for Education

DeskCAT Optical CT Scanner

The DeskCAT™ Multi-slice Optical CT Scanner for Education is ideal for safely demonstrating the following principles in a classroom or laboratory.

Acquisition: Projection images (analogous to digital radiography) of a translucent object, detector characteristics, multiple projection angles for CT reconstruction, fan and cone beam geometry.
Image Review: Pre-treatment of projection images for CT reconstruction, filtering, sinograms.
Reconstruction: Feldkamp back projection, variable resolution and voxel dimensions, image data management.
3D Image: Interact with the reconstructed image, demonstrate artifacts, adjust contrast (level, window).

User-friendly Software  

The DeskCAT™ scanner and software make it easy for students to learn about the principles of medical imaging in a classroom or laboratory environment by enabling students to acquire, review and reconstruct CT images without the use of potentially harmful x-rays.

Interactive Learning
The above screenshot shows the software layout, which includes 4 windows that display different views of the data. Each window can be enlarged to analyze specific results as necessary.

  A) The Camera View window displays the live projection images of the phantom inside the aquarium.
  B) The Centre Slice Sinogram window displays the centre sinogram of your scan and updates for each projection angle during a scan.
  C) The Slice Reconstruction window displays the reconstructed central slice and updates in ‘live mode’ for each projection angle during a reconstruction.
  D) The 3D Reconstruction View window allows you to observe, analyze and manipulate the images in 3D.

DeskCAT Testimonial

The Importance of Interactive Learning

“The teaching of the principles of Computed Tomography to a wide range of students in medical physics or medicine has been very challenging. The DeskCAT™ Scanner fills a real need by providing the educator and students with an interactive experimentally-based teaching tool used in the laboratory or classroom. By scanning a wide range of specimens, students of all sciences will find this  device very helpful in understanding optical techniques and CT reconstruction. I highly recommend DeskCAT™ to educators at all levels of undergraduate, graduate, and post-graduate programs.”
