Looking back and looking forward to: imaging technology 30 years development

People are aware, the doctor took a film that is invisible, touched by Ray through one's own body, a doctor will be able to take sick part see clearly and plainly.

Imaging technology in the medical field status is important, because this is the most intuitive way, to let the body's internal "molecular" hide trick or treat.

Medical development today, no imaging technology advances, disease diagnosis and treatment techniques forward almost even.

In the late 1970s, China began from abroad computer tomography (CT).

In the mid-1980s, the country also has a magnetic resonance imaging (MRI). As digital subtraction angiography (DSA), computer x-ray radiography (CR) and digital x-ray radiography (DR), now Department of Radiology doctors in the hands of the "weapons" is very diverse. 30 years of imaging technology development, with the Chinese medical radiological branch Chairman, University affiliated Professor Keith Chi Word to sum up, the radiology doctors are seeing more and more things, more and more "rich".

In the 1980s

At first glance, the latest CT is particularly excited that this is a "only heard but not seen" machine

Witnesses: white Kinga (Hegang city, Heilongjiang province he Group General Hospital Department of Radiology)

"You can't imagine, I first saw the new equipment, dumbfounded.

Because only heard the name, but not seen. "White Kinga told 1986 saw the imported CT is both excited and proud.

In 1985, white Kinga from Mudanjiang graduated from medical imaging, was assigned to the local Hegang city which is the largest hospital in the Department of Radiology.

"I went to the year that just caught up with the good. The Hospital decided to support the development of our Department of Radiology, bought imported (Shimadzu) CT scan, can be the whole body, the whole of the Daqing, Heilongjiang province, has a terrace. "He said.

Late 1970s and early 1980s, beginning in the area of radiation medicine and foreign standards, some have been out of reach of cutting-edge equipment in China, even in lands, municipal medical institutions are also able to find a "floor".

In the introduction of imaging equipment, radiation professional ushered in the first "golden decade", and cultivate a new generation of medical imaging professionals.

Hospital with CT, the most direct impact is that patients have immediately.

White Kinga recalled: "we are very busy and sometimes don't have time for lunch. The place, were previously required to do the whole-body CT, had to run to Shenyang, Tianjin, Beijing hospital. "White Kinga said:" you reckoned that patients to this trip, eating, housing, and much more. ”

"At that time, CT, x-ray machines were not able to check out the disease.

For instance of chest diseases and heart, great vessels, overlapping lesion can see clearly, pleura, septum, chest wall lesions can also be clearly displayed. Again such as acute Miliary Tuberculosis, Lung x-ray shows a miliary shadows take 3 weeks or so, some acute patients will not get a timely treatment. The application appears in the chest CT, miliary shadow will be displayed before the pulmonary parenchyma in Nodular lesions. "This machine is accompanied by white Kinga has nearly 20 years.

Link: China in 1978 by Peking Union Medical College Hospital introduces CT this new technology.

In a short span of 30 years, all over the country and even in the county town of hospitals total installed various models of CT machine thousands, CT throughout the rapidly expand, CT machine become indispensable in medical diagnostic devices.

The 1990s

After filming the drill black House, then to see magnetic resonance, the clarity of the gap to make you feel incredibly

Witnesses: fan tree peaks (Zhejiang Province Taizhou hospital Radiology)

"30 years ago, the image section of the working conditions of doctors is what it is that drilling black filming in the room, dry wood and photographer makes no difference.

"Fan tree said.

In 1994, Vincent tree peaks graduate.

He came to the Hebei Handan rural, found that there is an antique-x-ray machine in use. "And we speak almost on textbooks, x-ray films, film and photography, the first shot in the dark room, and then to the doctor to the developer, flushing, spend 3 minutes to 5 minutes to dry. In addition, into the black House is still unable to work right away, so let the eyes adapt to the Dim light. ”

Fan tree said, similar work experiences, many radiotherapy doctors became a master of photography and photographic enthusiasts.

After entering the fan tree peaks, graduated from Tongji University School of medicine to Taizhou hospital, start using magnetic resonance imaging for patients with a diagnosis. "How to explain this gap? anyway you used x-ray machine, and then to take this kind of magnetic resonance, resolving power gap will make you feel incredibly magnetic resonance clear. For example, a tumor, previously used x-ray machine, we can only see the tumor size and location, others know nothing, doctors concluded that also the ' about ', ' maybe '. Now, to see the patient's blood supply, can see the bleeding, infarction, inflammation, parasites, and other diagnostic information. ”

A stay of the black House through summits fan tree, said: "now Radiology doctors no longer need to wash the film, computer technology has replaced the film.

Radiology doctors just ' filming ', but also for patients in the next step of treatment to provide specific guidance and help, to participate in the entire treatment process. ”

Link: 1980, world's first magnetic resonance in the United States with Setup.

In 1985, was the first military medical university affiliated hospital of South hospital introduced our first magnetic resonance imaging machines. Through the 1990s, to 2000, China has over 950 a magnetic resonance imaging machines.

30 years of road still regret

"Throughout my development of imaging technologies, is based on the x-ray machine,

CT, MRI, etc. equipment development as a starting point, the 1990s initial shape modern medical imaging system. Today, radiology doctors see images, more and more clear, more and more ' rich '. "Qi JI said.

As Chairman of the China Medical radiological branch, Qi JI full experienced imaging technology for 30 years history.

He said that the previous doctors need will operate the machines, the radiology doctors, clinical medicine, only understand radiation medicine is not enough, you have to understand the physics, chemistry, mathematics, knowledge of computers, it is a versatile, doctors must possess solely on the basis of a radiology information to make a clear diagnosis.

New technological developments, old technology does not mean to be abandoned.

Qi-JI said that traditional x-ray machine in orthopedics has its own place, also because more and more concerned about the iatrogenic radiation, some not so high precision equipment, rediscovering the value of it.

Academician Liu Qing said that the development of medical imaging is mainly by the General morphology of the physical, functional, metabolism and gene Imaging transition, image analysis by the "qualitative" to "quantitative" development, diagnosis by film-like and read the film's digital production and the development of electronic transmission.

And molecular imaging technology also began in the beginning, this is the new direction of the 21st century, the possibilities to microcosm.

Review of 30 years of radiological road, an imaging experts not without regret to say: "30 years of progress, we rely on a variety of models, categories of imported image equipment development, device walking in front of the foreign equipment manufacturers as we cultivate a large number of Radiology doctors.

Domestic in equipment research and development has yet to take on a release of product, which say that it is a pity. ”
