Statistical model based iterative reconstruction in clinical CT systems. Part III. Task‐based kV/mAs optimization for radiation dose reduction

Purpose: For a given imaging task and patient size, the optimal selection of x‐ray tube potential (kV) and tube current‐rotation time product (mAs) is pivotal in achieving the maximal radiation dose reduction while maintaining the needed diagnostic performance. Although contrast‐to‐noise (CNR)‐based...
