Aim: The aim of this study is to compare the radiation dose in present Onco protocol and low dose protocol for head and neck and pelvic phantom in radiotherapy planning computed tomography and to establish diagnostic reference level. Objective: We conducted a following study to compare the radiation dose in standard protocol and the scan with different set of parameters. Methodology: A experimental phantom study was performed in CATPHAN 503 measuring 20cm to investigate the optimization of radiation dose for CT head and neck and pelvis by using different parameters available in CT control console. Result: The result showed significant change in radiation dose in terms of CTDIvol, DLP and effective with different combination of kVp and mAs without compromising image quality.
