SPIE - Education Principles and Advancements in X-ray Computed Tomography SC471

This course will present a description of the fundamental physics and mathematical principles of CT. Key system performance parameters and design tradeoffs are reviewed. Causes and corrections of various image artifacts are extensively discussed. Potential impact of image artifacts and performance parameters on other computer-based algorithms, such as CAD and 3D volume rendering, is outlined. The second part of the tutorial will focus on the recent technology advancements in CT. Basic principles, benefits, and inherent issues associated with the helical (spiral) CT, multi-slice CT, and volumetric CT will be described. Different reconstruction approaches to combat artifacts associated with cone beam and helical interpolation are examined. The tutorial will conclude with a discussion on the recent advancements in CT applications, such as cardiac imaging, perfusion, dual energy, and fluoroscopy.
