The procedure of CT scan-paranasal sinuses is as follow.
• On the CT table, we have to get into position with the help of CT technologist.
• When we lie on the table then there is the movement of the table within the centre of the
• Pictures are taken from many angles by forming area’s cross-section images through the
revolution of the X-ray tube around us.
