Abstract : In the recent years there has been an increasing use of Computed Tomography (CT) in diagnostic radiology, and introducing Helical Multiple-row Detectors Computed Tomography (MDCT) in the King Abdulaziz University Hospital, assessment of doses received by different radiosensitive organs during scanning is a requirement for radiation protection and patient's safety, in compliance with the principal of keeping balance between image quality and minimization of doses. The research project aims at reducing doses to primary target organs in the scanning process, without compromising the clinical needs, as well as keeping minimum doses to other organs from scattered radiation. Rando Phantom, shielding for different organs, CT pencil ionization chamber coupled with Radcal system and high sensitivity TLD-100H chips will be used for vartied CT imaging parameters such as kVp, mAs, CT slice width, etc. Dose reduction from scattered radiation with the introduction of shielding to the adjacent organs will be estimated by TLD technique characterized by high precision. The assessment of absorbed dose distribution in primary target organs; brain, eye lenses, thyroid, chest/breast and gonads during CT examination are envisaged. The expected outputs of the planned study are reduction of CT doses, shielding effects against scattered radiation during CT examination, increased patients' safety and quality control assurance relevant to current status of CT procedures being practice din KAUH as well as outside of KAUH, Jeddah.
