Innovations in CT dose reduction strategy: application of the adaptive statistical iterative reconstruction algorithm

AJR Am J Roentgenol. 2010 Jan;194(1):191-9. doi: 10.2214/AJR.09.2953.


Objective: The purpose of this article is to discuss the application of a new CT reconstruction algorithm, adaptive statistical iterative reconstruction (ASIR), to reduce radiation dose at body CT and to provide imaging examples in comparison with low-dose and standard-dose filtered back projection CT.

Conclusion: The ASIR reconstruction algorithm is a promising technique for providing diagnostic quality CT images at significantly reduced radiation doses.
