Iranian Researcher Wins Gold Medal for Secondary Radiotherapy Equipment

Sunday, March 30, 2008

Mojtaba Navabpour, an Iranian researcher, has manufactured a secondary radiotherapy machine for treatment of hepatic cancer, which brought him gold medal of Nuremberg International Exhibition of Inventions and Innovations in 2007.

Navabpour, who holds a doctorate in physics and medical engineering, has noted that during the exhibition, which was held in early November 2007, inventors from 34 countries including 24 developed and 10 developing states showcased their inventions in various scientific fields.

The radiotherapy machine ranked the first among 774 inventions in the field of medical technology and brought its inventor a gold medal.

He added that the equipment was produced in 1999 and after being tested on cancerous cells, another more powerful model was manufactured for treating patients.

He noted that manufacturing the equipment was not difficult and its importance lay in the physical mechanism involved and the secondary radiation that it produced.

Navabpour stated that in ordinary radiotherapy the amount of radiation is not adequate to treat the disease and a higher dose may damage patient’s cells.

“In secondary radiotherapy, a lethal dose is injected into malignant cells and normal cells receive less intensive radiation,” he said.

The researcher added that in ordinary radiotherapy methods, patients should undergo the process for 20 sessions, but the new method is implemented in a single session.

He stated that if the relevant permit is issued by medical ethics committee of Ministry of Health and Medical Education, the new equipment would be used to treat cancer.
Navabpour noted that the new method is less costly than previous methods.
