The objective of the study was to enhance patient safety and imaging efficiency by analysing the radiation doses received by organs in different head CT protocols. A female Rando phantom was used to simulate a patient, and thermoluminescent dosimeters were employed to measure organ radiation doses in various head protocols. Furthermore, CT-Expo software was used to calculate organ doses. The results indicated that scout images taken prior to CT scans have a considerable impact on patient radiation exposure, contributing approximately 4% and 23% additional doses to the eye lenses and thyroid in the headache protocol. The angled head CT protocol decreased eye lens and thyroid doses by 88% and 7%. Sinus CT scans resulted in doses of 11.9 mGy for eye lenses and 1.2 mGy for the thyroid, according to the CT-Expo software. In addition, head trauma patients faced higher radiation doses, particularly to the parotid glands, eye lenses, and thyroid. The study highlights the importance of considering scout image doses when assessing radiation risks for CT imaging procedures. It was also demonstrated that excluding eye lenses from the scanning area in head CT examinations significantly reduced radiation doses to sensitive tissues, such as the parotid and thyroid glands, as well as the eye lenses. These findings emphasise the necessity of standardising procedures for dose monitoring and optimisation in medical imaging to minimise unnecessary radiation exposure to sensitive organs.
