Because the lens is a tissue with the highest sensitivity, the lens shielding is very important in CT imaging. However, in clinical terms, there is a lack in the efforts in decreasing dosage on the lens, and the shielding of dosage and the effects on the imaging are researched using bismuth to evaluate the usefulness. As results of the dosage evaluation results, when there is no gantry angle when the thickness of the lens shielding material is 0mm, the dosage was 28.476mGy, and when there is gantry angle, the dosage was 20.852mGy that it was confirmed that the dosage was 27% lesser with gantry angle. It was confirmed that the dosage value decreased with the increase of thickness of lens shielding material when there is gantry angle, and when the lens shielding material was 1mm, the dosage decreased by approximately 39% compared to when it was 0mm. When there is gantry angle, the dosage values were respectively 12.788mGy and 12.776mGy for the crystalline lens shielding material thicknesses of 0.75mm and 1.0mm. In image analysis, the quantitative evaluation and the qualitative evaluation were almost constant regardless of the thickness of the lens shielding material. The optimal lens shielding material thickness to minimize the does of lens and increase the value of diagnosis in Brain CT examination is 0.75mm. Therefore, if this is utilized for easier use in clinical practices, it is considered to be able to contribute to not only the protection of the lens but the accurate diagnosis of diseases.
