Elimination of biological and physical artifacts in abdomen and brain computed tomography procedures using filtering techniques.

Introduction: Medical images are usually affected by biological and physical artifacts or noise, which reduces image quality and hence poses difficulties in visual analysis, interpretation and thus requires higher doses and increased radiographs repetition rate.

Objectives: This study aims at assessing image quality during CT abdomen and brain examinations using filtering techniques as well as estimating the radiogenic risk associated with CT abdomen and brain examinations.

Materials And Methods: The data were collected from the Radiology Department at Royal Care International (RCI) Hospital, Khartoum, Sudan.
