Task-based image quality assessment for CT optimisation

Current metrics for measuring CT image quality are often unrepresentative of clinical utility or highly subjective in nature. Task-based image quality assessment enables objective, quantitative measurement of the visual detectability of image features to an observer. This facilitates fast, direct comparison between CT systems and protocols. This talk will discuss the principles of task-based image quality assessment, and share how it is being used to optimise imaging in Lincolnshire.
