How much room for imagination is left in the 70 years of medical imaging equipment changes?

The medical industry in New China has gone through seventy years of ups and downs

An X-ray machine that no one knows how to use

In 1954, a nursing home specialized in treating tuberculosis patients in Qinhuangdao City introduced the unit's first medical imaging equipment, which was a 100mA X-ray machine made in Hungary

Recalling 67 years ago, Li Changtai said: “At that time, this kind of equipment was rare in China.

The 16-year-old nurse Li Changtai was entrusted with an important task and began to explore with colleagues to use X-ray machines to take pictures of patients

In the 1950s and 1960s, the incidence of tuberculosis in China was still high.

The strategy adopted by the state at that time was to "proactively find patients in X-examination", and extensively carry out group inspections in urban industrial and mining enterprises and institutions

It was also during this period that the construction of tuberculosis prevention and treatment institutions was greatly developed.

In the beginning, X-ray machines were not popular in primary medical institutions, and many tuberculosis patients only saw this equipment when they organized their physical examinations

Li Changtai said that in the nursing home at that time, doctors mainly made general judgments on the development of the disease based on the clinical manifestations of the patients.

"After the film is taken, the internal conditions of the patient can be seen very clearly.

After the sanatorium received new equipment, the young and capable Li Changtai was sent to Tianjin No.

Compared with the small city sanatorium, the equipment here is newer, better, and there are more in number.

After returning to the nursing home, Li Changtai gained a new identity as a "professional filmmaker".

The miniature change from import to domestic

Nowadays, many medical universities have opened medical imaging majors, and students can learn the basic theoretical knowledge of basic medicine, clinical medicine and medical imaging, and accept routine radiology, CT, magnetic resonance, ultrasound, DSA, nuclear medicine imaging Basic training for learning and other operational skills

Nevertheless, after entering the hospital, medical students who have truly begun to contribute to the relief of human diseases still often feel that they have more than enough energy

Medicine is a complex and profound knowledge.

Xu Guochang said in an interview with Cyberlan that when he returned to China from abroad, his biggest feeling was that the British machine could scan the whole body, but most doctors in China have not seen it, and they are still very concerned about radiation and self-protection.
Very at a loss, some doctors even wear a "leather jacket" and a white lab coat as work clothes
.

"The image quality at the time was very poor.
Only particularly complicated diseases could be used for approval once with the hospital's superiors.
There was no way to achieve multi-slice comparison, and even patients didn't know what the machine could detect.
Some thought it was a treatment device.
, Lie down in front of the machine to cure the disease
.
" Xu Guochang recalled
.

As the country attaches importance to medical technology, domestic equipment manufacturing has gradually entered a state of acceleration
.
Xu Guochang said: China's first ECG machine was first available in Shanghai, but its performance was unstable and it could not be mass-produced
.
Later, when I went to study in the South in the 1960s, I saw the domestically produced products being put into use, and then I saw it after the 1970s
.
Gradually there are integrated circuit types
.

Similarly, in the 1960s, Li Changtai's nursing home once again ushered in new equipment, which was a domestic X-ray machine
.

Compared with the obsolete Hungarian X-ray machine, this domestically-made device has accompanied the nursing home for a longer period of time.
It was not until 1985 that the only medical imaging device in the hospital was announced to be retired and replaced by another one.
A 500mA X-ray machine made in Shanghai, worth 100,000 yuan
.

Looking back on the past, it is not easy for domestic imaging equipment to go from a blank to today's prosperity
.

In 1895, the German physicist Roentgen discovered X-rays, and this discovery made him the first Nobel Prize winner in physics
.
Only two years later, in 1897, Suzhou Bo Xi Hospital introduced the first X-ray machine from the United States
.

After the founding of New China, the construction of medical equipment was stepped up
.
In 1952, the first domestic 200mA medical X-ray machine "National Day" came out.
The equipment was successfully developed by Shanghai Precision Medical Instrument Factory and was installed and tried in Zhongshan Hospital
.
At the end of 1959, the factory successfully trial-produced a 400mA X-ray machine
.

Since then, domestic X-ray machines have been mass-produced, and medical work has also taken a big step forward
.

At that time, Li Changtai, who was buried in the first medical book, did not know that a brand-new domestic imaging device would come to his work in a few years, and in the next 20 years, he would work with him to relieve the pain and suffering of patients.
Watch the new life

How much room for imagination in medical treatment?

The medical industry is a knowledge-intensive industry.
For many medical workers, the concept of lifelong learning is inscribed in their bones
.
Learning has become a habit, a daily life
.

Many grassroots medical workers in the last century have not received formal and systematic professional learning.
The occasional short-term expatriate training opportunities that may appear are extremely precious, and self-study is a routine operation
.

Xu Guochang said: At that time in Jinan, the opportunity to study abroad was very precious.
The most memorable thing is when I saw the first NMR.
At that time, it was not made in China, but it was imported.
It was developed by the Chinese Academy of Sciences in cooperation with a company.
The first MRI system in China that was released was later used in hospitals.
It was only available for approval when used, and the price was naturally very expensive
.

In the 1970s, the nursing home where Li Changtai was located merged with several other hospitals and was no longer a specialized tuberculosis prevention and treatment institution.
There were more patients coming to see the doctor, and the types of diseases he suffered increased, and orders began to appear on X-ray films.
It is difficult for doctors to judge image information
.

During that period, Li Changtai took a train to Shanghai, more than a thousand kilometers away, to find a well-known expert across the country to watch a movie and ask him to help analyze his condition
.

Li Changtai learned a lot from experts? "No.
The
experts are very busy.
Many people come to see him to watch the film.
They are all rushed there
.
He just watches and analyzes the problem.
There is not much time for communication
.
"

In fact, whether in the last century or now, the imbalance of medical resources is a common problem of every era
.
However, advances in technology have greatly accelerated the overall operating efficiency of the medical system
.

In recent years, with the continuous advancement of hierarchical diagnosis and treatment and the construction of medical consortia, the medical ecological landscape has taken on a new look
.
In the remote imaging diagnosis center, with the help of an information platform, doctors in the Medical Union can conduct online image reading, diagnosis, and difficult imaging consultations
.

From traveling thousands of miles to exchanges with Taiwan, the new China's medical development has gone through 70 years of ups and downs
.
The grassroots doctors of the last century may have long been unable to understand the operating modes and operating methods of today's CT and nuclear magnetic equipment, and can no longer provide patients with diagnosis and treatment conclusions that they have relied on years of experience and continuous accumulation
.

But the mountains and rivers remain the same, and there are later generations
