Dear colleagues, Friends and distinguished Guests.

 On behalf of the congress committees, it gives me great pleasure to welcome you all to 17th Congress of Iranian Radiographer Sciences Association.

This congress is an opportunity to share expert knowledge and learn the principles of radiation protection, imaging sciences and provide the best diagnostic and therapeutic methods.

By pursuing scientific progress and enhancing the educational capabilities of Radiographers in Iran, the Iranian Society of Radiography has tried to provide the best possible results by holding scientific conferences and presenting the latest research papers.

We have tried to turn this Congress into a great success in all fields of imaging sciences so that all participants in Congress can benefit.

Once again, on behalf of IRSA would like to welcome you and wish you a happy and successful Congress.
