| Abstract: | The dose distributions of head,maximum surface exposure,organ doses and effective dose equivalent in computed tomography of headusing Hitachi CT-W_4 scanner(20 slices).Were estimated with thermolumi-nescent dosimeters and a human body phantom.The formulae for estimatingdoses for were derived. |
