摘要：
Computed Tomography (CT) scanner manufacturers and users are aggressively pursuing radiation exposure reduction strategies for cardiovascular imaging. Strategies include the design of scanner hardware to prevent X-rays not contributing data to image formation from reaching the patient, user manipulation of scan parameters to decrease the number and/or energy of the X-ray photons interacting with the patient, and hardware and software improvements to increase efficiency of data detection and utilization. This paper provides an overview of CT technology with an emphasis on dose related features and scan parameters and describes in detail the options currently available for reducing radiation exposure with cardiovascular CT.
