Abstract: 

Background: The increasing incidence of infertility is alarming. About %30-10 Background: Given the importance of CT imaging in the diagnosis and treatment of diseases, the concern of the dose that patients are receiving while undergoing CT examination and the lack of information about the situation in the centers CT scan was conducted at Shahid Beheshti University of Medical Sciences.
Methods: A descriptive study was conducted. A list of CT scans of patients who are still under the supervision of Shahid Beheshti University of Medical Sciences were prepared (the public sector). Exposure data were collected via referring to the centers (kV voltage level and mA and scan time) and two methods were used and back up CT scan of the patient's history was carried. Dosimetry on phantoms, phantom head and body with the same exposure conditions (radiation) was performed and the organ dose and effective dose received by mili Gary was calculated according mili Sivert.
Results: The research was conducted in five centers with CT scan. In CT scan of the head (head CT) brain dose, the highest dose (31.55 mG) and bladder lowest dose (zero) and in CT scan of the chest (chest CT), breast highest dose (20.67 mG) and bladder lowest dose (0.005 mG) and in CT scan of the abdomen and pelvis (abdominal pelvis) bladder highest dose (16.44 mG) and brain lowest dose (0.002 mG) was calculated. Furthermore, effective dose received by patients for three protocols of the head, chest, abdomen pelvis centers surveyed, respectively. The lowest effective dose for the patient CT scan of the head (1.55±0.16 mSv) and the lowest effective dose for the patient CT scan of the chest (3.4±0.3 mSv) and the highest effective dose received by patients CT scan of the abdomen pelvis (6.8±0.3 mSv), respectively.
Conclusions and Recommendations: It seems organ dose and effective dose in some higher centers of the world standard (ICRP) and the overall dose exposure is a concern.
