Tomsk development will reduce the dose for X-ray examination

Scientists Tomsk State University (TSU) developed the technology to create gallium arsenide sensory structures and X-ray detectors based on them, which reduce the radiation dose received by the patient during X-ray examination, told RIA Novosti on Friday, general director of OOO "gallium arsenide sensors" Maxim Chepezubov.

According to him, since the 1960s in the detectors for X-ray machines as an absorbent material used semiconductor silicon. However, manufacturers need an alternative material that exceeds silicon in radiation resistance and at the same time will reduce the radiation dose to the patient.

"We propose to bring to market a sensor material based on gallium arsenide. This material can reduce the radiation dose to man, and get better quality X-ray images," — said Chepezubov. 

He noted that earlier gallium arsenide could not be used in X-ray machines because of its specific properties. However, researchers headed by Professor TSU Oleg Tolbanova could enter into its composition chromium, resulting material was suitable for X-ray detection. "This development is unique, unparalleled in the world" — the source said.

According to him, with the successful development of the project in Tomsk planned to set up the production of the material, it will set up with the participation of the TSU and the Nanotechnology Center of "RUSNANO" enterprise "gallium arsenide sensors." Nanotehtsentr will finance the first phase of the establishment of pilot samples sensors for further testing of the material on the X-ray equipment.

Partner of the project in terms of testing may be one of the divisions of Samsung Inc., Specializing in the development of medical technology. "Our specialists Samsung Inc. Appreciated available developments and prospects for the creation of a new generation of malodoznyh detectors for mammography, dental imaging," — said Chepezubov.
