摘要
As multi-detector-row computed tomography (CT) technology evolves, manifold applications of CT scanning have been adopted in clinical practice and optimization of scanning protocols to comply with an "as low as reasonably achievable" radiation dose have become more complex. Automatic exposure control techniques, which have been recently introduced on most state-of-the-art CT equipment, aid in radiation dose optimization at a selected image quality. The present article reviews the fundamentals of automatic exposure control techniques in CT, along with the scanning protocols and associated radiation dose reduction.
