Our country to introduce first 7T NMR to lay the Foundation for research and development scientist

Recently, China's first 7T (Tesla) Siemens-body MRI System power on the ceremony of the international high-field MRI System peak seminar held in Beijing, from more than 20 countries and regions.

The introduction of our first, Asia 2, 7T NMR imaging system is currently the world's most powerful imaging equipment, Institute of Biophysics, Chinese Academy of Sciences has been in before installation is complete, it will be used for functional brain imaging of scientific research.

According to the Institute of Biophysics, Deputy Director of the cognitive laboratory, measure takuhiko magnetic resonance system capable of the most critical factor is the signal to noise ratio, the greater the magnetic field of the corresponding higher signal to noise ratio.

Familiar medical NMR magnetic field strength of approximately just as 1.5T and biophysical the previously used 3T systems. Since the sensitivity is low, is not applicable to further expand scientific research.

The introduction of 7T system can detect the past cannot detect function signal, as research such as depression, dementia, drug addiction, Internet addiction and other disorders of an important means.

More significantly, 7T system spectrum Imaging resolution high, plus it is a lot of nuclear imaging, Physiology and metabolism of nuclear imaging plays a very important role, will significantly increase the brain's cognitive function and disease control research areas.

Takuhiko said: "this device in strong magnetic fields can make Imaging observation more sharp, fine structure of the brain is more clear.

”

In fact, the introduction of 7T NMR imaging system does not mean "everything, use".

Researchers also need to import this new creative convergence of devices, connectivity and integration, find this instrument applies the best conditions to make it more perfect to brain imaging studies.

In addition, 7T and later ultra-high field systems transmitting, receiving system and related studies, always a coil is the focus of competition among scientists.

At present, our scientists have the subject of research and development, and debugging capabilities.

Takuhiko told reporters that the Visual stimulation organisms physical rendering and reaction signal synchronous recording system, high-magnetic field 32 lead synchronous EEG recording system, monkeys functional magnetic resonance laboratory system and the central data processing and storage systems, has acquired no small accomplishment.

"This proves that we are fostering a considerable strength of talent.

"Academician chenlin stressed that" the success of this post is of great significance for our future developed higher magnetic field strength of the magnetic resonance imaging system laid the Foundation and accumulated experience. Soon, we may use their own development of more advanced instruments. ”
