Abstract

Effective dose analysis research has been carried out on head CT scan. The research was conducted at RSUD Sanjiwani Gianyar using secondary data from head CT scan, namely the value of CTDIvol, DLP, current, voltage and scan length. Data are grouped according to age and gender, namely ages 0-4 years, 5-14 years, and over 14 years. The effective dose value is obtained from the product of the DLP value with the conversion factor k. Effective dose analysis was performed using standard DRL values ??for Bapeten Head regulation and ICRP 102. The effective dose of each group was obtained, namely male patients aged 0-4 years were 2.34±0.04 mSv and female patients were 2.4±0.28 mSv; age 5-14 years, male patients were 1.96±0.45 mSv and female patients were 1.89±0.32 mSv; age over 14 years, male patients were 1.88±0.35 mSv and female patients were 1.8±0.35 mSv. The values are still in accordance with the standard determined by Bapeten and ICRP and the CT Scan plane is still suitable for use for a CT scan of the head.
