The reconstruction algorithm , adaptive statstical iterative reconstruction(ASIR) , has been introduced that effectively increases image quality by reducing noise .
Iterative recontruction methods are different from filter back projection (FBP) technique that has been used for redusing image noise. In FBP, projection data are filtered and then pushed back along ray paths to form image pixels.
Iterative reconstruction is more straightforward and complex as well , computing image data iteratively via statistical reconstruction algorithms and algebraic reconstruction techniques that predict the characteristics of missing data using any number of factors , from nearby data in the same image to comparable anatomic images from reference database.
The purpose of this study is to evaluate the dose reduction and image quality in paediatric head,chest and abdomen CT examinations , using ASIR
