Measurements Absorbed Doses to Some Organs during Head CT Imaging

T. M. Taha, S. H. Allehyani

Purpose to measure absorbed doses to brain, eyes and thyroid organs during head computed tomography imaging. Materials and Methods. Thermoluminscence dosimeters, TLD-100 placed inside the Head CT dosimetry phantom at four peripheral and central holes and irradiated to reference dose of CT beam. Results: The weighted dose conversion factor for TLD (s) at four peripheral holes and central hole of head phantom, at 120 kV and 400 mAs is generated. The mean absorbed doses to brain, eyes and thyroid during head CT protocol using phantom of human are found to be 1.02 mGy, 1.17 mGy and 0.99 mGy respectively. Conclusion the mean absorbed doses to brain, eyes and thyroid organs are lower than International Commission of Radiological Protection recommendations.
