This course provides a general overview of X-ray computed tomography (CT), covering its historical development and diverse applications in medicine, research, and industry. It introduces the fundamental principles of X-ray interaction with matter, including attenuation and beam hardening. The course details various CT instrument configurations: medical CT, microCT, and synchrotron-based systems. The mathematical basis of image formation are described in terms of the Radon transform. Analytical reconstruction via filtered back-projection and iterative reconstruction methods (e.g., SART, SIRT) are derived and explained. Finally, techniques for interpreting and visualising volumetric data, such as tomographic slicing, segmentation, and isosurface rendering, are discussed.
What you will learn:
- Describe the essential components of a CT instrument and explain the mode of operation of such instruments
- Explain the fundamental physical mechanisms that lead to image contrast
- Define the Radon transform and explain describe the most common reconstruction strategies for CT data
- Describe visualization approaches for reconstructed volumes
Course enrolment will open on March 23.
