[Source: ScienceDaily] - Computed tomography (CT) scans are responsible for more than two thirds of the total radiation dose associated with medical imaging exams. However, a newly adapted low-dose technique called adaptive statistical iterative reconstruction (ASIR) may enable radiologists to reduce patient radiation resulting from CT up to 65 percent, according to a study published in the September issue of the American Journal of Roentgenology (AJR).
Iterative reconstruction is a technique that allows radiologists to reduce the noise in an image and improve image quality (like adjusting a TV antenna to make a "fuzzy" image sharper) while significantly reducing the radiation dose.
