In the past, the global medical device market was monopolized by European and American countries, accounting for 80% of the market share. China can only import equipment from them at a high price, which has paid a heavy price. According to statistics, China spends sky-high prices on imported medical devices every year, of which the most expensive is the nuclear magnetic resonance instrument. Known as "the king of medical equipment", this instrument has incomparable advantages in diagnosing various diseases.
However, after 20 years of unremitting efforts and innovation, China has finally made a major breakthrough in the field of medical devices. In July 2023, China successfully mass-produced 3.0T nuclear magnetic vibrator, and developed the world's most advanced 5.0T nuclear magnetic vibrator for the first time. These two instruments surpass European and American products in imaging quality and speed, but the price is only 1/5 of European and American products.
Basic principle of nuclear magnetic vibration machine
The nuclear magnetic vibration machine puts the human body in a special magnetic field, and uses radio frequency pulses to excite the hydrogen nuclei in the human body, so that the hydrogen nuclei vibrate and absorb energy. After stopping the radio frequency pulse, the hydrogen nucleus sends out a radio signal at a specific frequency, and releases the absorbed energy, which is collected by a receiver in vitro and processed by an electronic computer to obtain an image, which is called nuclear magnetic resonance imaging.
Nuclear magnetic resonance (NMR) vibration is a physical phenomenon. As an analytical method, it is widely used in physics, chemical biology and other fields. It was not used for medical clinical examination until 1973. In order to avoid confusion with radiological imaging in nuclear medicine, it is called magnetic resonance imaging (MR).
