New Developments of DeskCATTM: A Multi-Slice Optical Scanner for Teaching CT and SPECT Imaging Principles |
| Abstract: |
DeskCAT is teaching device that helps explain the principles of medical imaging in an interactive and student-friendly way. It is an optical CT scanner that uses visible light rays instead of x-rays which makes it safer for use in the education environment. The system is manufactured as a commercial product (http://www.deskcat.com/) and it includes a set of a "plug 'n play" lab modules. There are three sets of Lab Exercises:
In the beginner labs, students explore 3D medical imaging by localizing fiducial markers, measuring linearity by acquiring scans of various optical attenuation pins, and assessing spatial resolution by imaging an optical line-pair phantom.
In the intermediate labs, students explore a Fourier technique to determine the Modulate Transform Function (MTF) of the scanner, learn the importance of the contrast-to-noise in the context of low-dose imaging and also recognize common artifacts in CT images caused by incorrect or incomplete projection (radiographic) data.
In the advanced labs, students observe performance differences between fan-beam and cone-beam CT systems, investigate SPECT-CT with attenuation corrections based on transmission CT images of the same phantom without light excitation. They also learn how Dual Energy CT (DECT) can be used to discriminate structures according to their differential absorption at various wavelengths. The system is now used routinely at Western University and more than 50 other universities and training centres with medical physics or radiation technology programs. It has also been used for public education. |
