CT scanning protocols, which specify image acquisition and reconstruction parameters, need to be optimized so that minimum radiation dose can be used to achieve sufficient image quality for specific diagnostic tasks. To achieve this goal, the relation among image acquisition parameters, image reconstruction algorithms, image quality, and radiation dose must be clearly understood. This lecture will provide an overview on how to optimize image acquisition and reconstruction parameters in multi‐slice CT. Learning Objectives: 1. Understand how the CT acquisition parameters (helical pitch, collimation, detector configurations, etc.) affect the image quality. 2. Understand how the reconstruction parameters (kernel, slice thickness, etc.) affect the image quality. 3. Understand how to optimize the acquisition and reconstruction parameters for different diagnostic tasks in order to improve image quality or reduce radiation dose.
