Answer to the question "Northeastern University independently developed China's first ct machine" is as follows:
In 1989, domestic CT ushered in the first step of "from scratch", the computer imaging center of Northeastern University was formally established in that year to take over the project of developing the whole CT machine, which was highly valued by the state and included in the national "torch". In 1989, the computer imaging center of Northeastern University was formally established to take over the project of developing a domestic CT machine, which was highly valued by the state and included in the national "Torch" program.
Expanding knowledge:
CT has a core technology called array processor, if you can't overcome this technology, the development of domestic CT is bound to stagnate, but this kind of core technology is bound to be the highest level of commercial secrets, foreign big brands who do not regard it as life, how can it be shared with outsiders.
The Alpine R&D team at Dongda University, which has an advantage in computer technology, has taken advantage of its strengths and avoided its weaknesses by innovatively replacing the array processor with a PC, which not only realizes the technological breakthroughs of the core system of the domestic CT, but also creates a new change in the international CT technology. Since then, large foreign CT manufacturers have also begun to learn to follow suit, and have unloaded the expensive array processor, replaced with a cost-effective PC machine.
In 1994, the dream of "developing Chinese CT" finally became a reality, and the first domestic whole-body CT prototype was successfully developed and passed the national test!
In 1995, the Computer Imaging Center of Northeastern University, together with the domestic CT project and the domestic CT prototype, was incorporated into Neusoft Group. In August 1997, the first domestic CT-C2000 with independent intellectual property rights developed and produced by Neusoft Medical was awarded the production license certificate issued by the state authorities, and more than 50 units were sold in the following year, and was selected as one of the "Top Ten CT Technologies in Asia" in 1998. In 1998, it was selected as one of the "Top Ten Scientific and Technological Advances in CT in Asia".
In 1998, Neusoft Medical was formally established, and the domestic medical equipment represented by CT was developed towards industrialization and scale. By then, the domestic CT successfully completed the industrialization conversion and put on the market, and began to fight with the international big-name manufacturers in the CT market, which also marked that China became another country capable of successfully developing CT after the United States, Japan, Germany and the Netherlands!
The introduction of domestic CT, not only to fill the gap in China in the large diagnostic and treatment equipment market, so that foreign second-hand equipment was forced to withdraw from China, but also make multinational CT products have no choice but to reduce the price of 20% to 30%, after-sales service prices reduced by more than 50%, for patients, the cost of the examination has also been reduced to one hundred dollars.
Subsequently, CT-C2000 passed the European CE certification and the U.S. FDA certification in 2000 and 2002, and began the journey of domestic CT from scratch, from the domestic market to the international market. In addition, Neusoft Medical, as the "originator" of domestic CT, has not stopped its technological progress at all.
In 2009, Neusoft Medical successfully developed China's first 16-slice CT with independent intellectual property rights in core technology; in 2012, China's first 64-slice spiral with independent intellectual property rights was also launched, in which the core components such as the bulb tube, detector, high-voltage generator, and data acquisition system have reached the international level in terms of technology and industrialization.
At the same time, a number of other medical equipment companies have also begun to emerge in the country to join the ranks of CT research and development and production. "China's smart" key areas of high-performance medical equipment is entering a key stage of intelligent manufacturing to seek innovative development.
Here, the story of China's first self-developed CT has come to an end. But Neusoft Medical, which single-handedly created China's first CT, has two other new achievements worth mentioning in recent years.
In 2019, China's first ultra-high-end CT with independent intellectual property rights, Neusoft Medical 256-layer wide-body energy spectrum, was officially granted a medical device registration certificate by the State Drug Administration. Since then, China's CT officially ushered in the era of ultra-high-end CT, China's independent research and development in the field of ultra-high-end CT has stepped into the "international level".
