I am studying and eating melons in Chronicle

Sudden.

An idea came to her mind, almost like boiling water to make ice.

If they don’t have a CT machine, can they build one themselves?

According to a brief history of the future: In September last year, an electronic engineer from Eagle Country had already installed a scanning device he designed and manufactured in a suburban hospital, which is a simple scanning device that can enhance the X-ray radiation source.

In October, the hospital successfully completed a head CT scan of its first patient using it.

If foreign countries can do it, why can’t they?
The first-generation CT machine used a rotation-translation scanning method, but her goal was far from stopping there.

Yunling thought that if we want to do it, we must go to the extreme, try our best to "squeeze" the existing scientific and technological means, and achieve it in one step.

She didn't dare to dream about spectrum CT machines and photon counting CT machines, so she could always think about the fifth-generation spiral CT, right?
In fact, the improvement of the spiral type lies in the scanning method at various angles.

The first four generations all used X-ray tubes as the emission end for rotational scanning, and even the first two generations basically used rotation and translation. The scanning speed and performance of X-ray tubes that relied on mechanical rotation were relatively limited.

The spiral fifth generation uses the X-ray tube in a huge circle that surrounds the bed where the patient lies.

During the rotation of the internal rotor, the direction of the emitted electron beam is controlled by the deflection coil, and scanning can be completed quickly in all directions.At the same time, scanning rotation can be achieved directly by controlling the coil current, so the rotation speed can be greatly increased.

Moreover, the fifth-generation CT can not only image the head and abdomen, but also can act on the heart.

Yunling sat on the chair, her heart racing, as if she wanted to start planning immediately.

However, the ideal is full, and the reality is very skinny.

As soon as she got started, she found that she had no way of starting.

No matter how loud the slogans are, they cannot cover up the large gaps left in science and technology.

Yunling suddenly felt that she was digging the ground. She originally thought that the hole in the ground was caused by mice. The simplest solution was to dig up the soil, remove the lesions, and then fill it up.

But now, the more she dug, the more she discovered that the hole inside was getting bigger and bigger.

A CT is not just a piece of paper. This actual industrial product involves all aspects of knowledge disciplines - mechanical engineering, data acquisition and processing, computer science, materials chemistry, medical imaging...

Due to some current technical limitations, she not only had to improve the manufacturing principle structure of the CT machine, but also had to trace back many of the detailed knowledge and theories involved, and then fill them in until it was consistent with the current subject frontier.

It's as if this hole can never be filled...

Even though she knew the answer, it was still a huge project to work backwards.

To be honest, Yunling thought to herself: It would be better to do nothing and just wait for seven days. When the system comes out, everything will be fine.

But she also felt that this would result in her losing her subjective initiative.

If there is no system, wouldn’t these things be done?

Of course it still has to be done.

It's just that she won't be able to complete it. Relatively speaking, China's successful independent research and development will have to be delayed by 20 years.

Even if her abilities are limited, why not do what she can?
If she blindly relies on the system, sooner or later she will completely lose her ability to think and act independently. This will not be her.

Yunling breathed a long sigh of relief, picked up her pen and began to write the title - the basic structure and working principle of medical equipment CT machines.

……

"What's going on over there?"

Yunling has been unusually quiet these past two days.

Although she was originally a quiet person, Ling Li was very surprised that she was not used to being completely confined in a room and having her movements restricted.

This made her wonder, has this little girl had such an experience of being locked up before?Chen Chen also found it strange: "These days, apart from going to the toilet and being accompanied by a female colleague the whole time, her only requirement is to add paper and ink."

"Is it possible that she is really studying a treatment plan?" Ling Li wondered and said to himself, "By the way, where is the feedback from the village?"

When mentioning this matter, Chen Chen hated the irony: "Alas... those two young people didn't ask anything. They even went to contact Yunling's closest friend - Chu Silan, but they didn't ask anything. They just said they didn’t know each other well.”

"It doesn't matter?" Ling Li asked again.

"At the moment, that seems to be the case."

She took a deep breath: "What's the comparison between the two reports?"

Chen Chen's eyes lit up: "This is quite interesting! My colleagues in the identification department also specially found a medical student who graduated from the university to assist in the detection. After three repeated comparisons in various dimensions, it was basically determined that the two reports were about [-]% similar. "

"But I can finally catch a piece of wool." Ling Li's heart that had been holding on finally fell to the ground slowly.

She made a conclusion: "That means there is no way that they are not related to each other."

"Chen Chen, you go notify the trial experts over there and tell them to use Yunling or the report as an entry point. There will be unexpected breakthroughs."

"Yes!"

Although there is only a little progress, it is nothing short of exciting.

If one road doesn't work, find another.

Isn't there a saying that goes well - all roads lead to Rome, and water flowing thousands of miles back to the sea.

Different routes lead to the same goal.

Yunling was not yet aware of the upcoming risks, but Fu Chengxu felt uneasy, as if something worse was about to happen.

It seemed that it had been several days since he had been moved here from the farm, and the number of days had not been calculated.

Of course, modern interrogation will not give in, but to cover up a lie perfectly, you need to anticipate all the other party's logical attacks in advance, and you also have to put yourself in an uninformed position with blind spots in your perspective.

This causes the brain to have no time to breathe and is in a state of constant tension.

As the night fell, Fu Chengxu lay exhausted on the hard bed. When he raised his head, he could see the dormitory building opposite through the small window on the high wall. There was always a light left on.

He didn't know who it was.

But when I think that in the vast and endless desolate darkness, there is still a faint halo of light, like a star, illuminating this dark sky, I feel soothed.

This feeling is similar to the substitute comfort psychology——

He can't get out for a while, but the light is always free.

Fu Chengxu wasn't sure if there would be a bug here, so he didn't even dare to talk to himself casually. He could only think slowly in his heart:
"I wonder if they would believe what he said?"

"If he doesn't believe it, what will be his end?"

"But his only solution at the moment is to hold on to it. Anyway, he is just a transfer officer and doesn't know anything else."

"..."

"Will it involve her?"

To the end of each meditation, the only uncertainty he worried about was another "accomplice."

In other words, I can actually stay at home for a month without going out, provided that the water and electricity network is constant, and I have no worries about food and drink. This is not very comfortable!It belongs to my paradise.
