Chapter 725 Data Originalization and Reconstruction

"Huh?" Old Director Chen was taken aback.

Zheng Ren held the patient's CT film in his hand, and countless thoughts flew into his mind.

In the ruins of Nanchuan Town, the operation between life and death caused him to touch the big technical shackles, and broke these shackles unintentionally.

Although it is only reflected in the operation for the time being, Zheng Ren knows that his ability to read films must have undergone a huge change.

During the operation at Pengxi Township Hospital, every time I saw the patient's X-ray film, more relevant information appeared in my mind involuntarily.

If it wasn't for being on the front line, with countless wounded waiting for treatment, Zheng Ren would have been unable to hold back his curiosity to ponder it for a long time.

At this moment, facing a patient with abdominal pain, the film that Zheng Ren saw was different from the clip that appeared in his mind.

The CT film was simplified, turned into data, and then fused in the mind to become what Zheng Ren wanted.

Because Zheng Ren saw the patient's diagnosis, the burden of completing all this was not heavy. He immediately found the abnormal points in the film and found the problem.

Looking at the CT film in front of me, there is only a little vague abnormality. If you don't identify it carefully, this is an ordinary CT film of retroperitoneal hematoma. And that point of abnormality can be judged as fat shadow or artifact.

However, when Zheng Ren watched CT films now, it was a different scene.

Su Yun leaned over, frowned and asked, "Boss, I'm fine with this movie."

Old Director Chen was also very strange, but he didn't speak. The experience in Nanchuan Town made him realize the specialness of this young doctor. Otherwise, they wouldn't have made a special call to ask Zheng Ren to come over.

"Su Yun, look..." Zheng Ren said, suddenly remembered something, and immediately said: "Director Chen, micro pump, lower blood pressure, control the patient's blood pressure. The patient is in severe pain, first push 5mg of morphine."

Zheng Ren spoke very politely, but with a confident expression and a tone that could not be refused, it was a standard superior doctor's posture.

Although Director Chen was puzzled, he did not refuse. He immediately called the nurse, and according to Zheng Ren's instructions, first pushed 5mg of morphine, and then installed a micropump to inject sodium nitroprusside intravenously to control blood pressure.

Now the patient cannot be moved, and Zheng Ren has nothing to do in a hurry.

Although the blood pressure on the ECG monitoring is not high, there is still the possibility that the blood pressure suddenly rises during the moving process and breaks through the abdominal aorta.

Be sure to control your blood pressure first.

This point is similar to the first time I went to the imperial capital and predicted Cui Heming's thoracic aortic dissection on the plane.

It's just that now there are micropumps and various drugs, and everything is much better than the conditions on the planes before.

Seeing that the other side was busy and wouldn't be having surgery for a while, Su Yun refused, grabbed Zheng Ren and asked, "How did you find out? Anyway, the patient can't be moved for the time being, so hurry up and talk about it."

Zheng Ren nodded, and walked to the doctor's office with the film.

The film reader is on, and there are two films inserted in it.

Zheng Ren packed up the films inserted in the film reader, found the film bag according to the time and name in the upper right corner and put them away, and then inserted the abdominal CT of the patient with abdominal pain into the film viewer.

"Here, look carefully." Zheng Ren said: "It looks normal, like a normal blood vessel structure. But do you feel that the density is different from the surrounding blood vessels?"

He pointed to a point on the film and said with certainty.

Su Yun stared at the position of Zheng Ren's fingers with a strange expression.

"It's like this, you arrange the pixels in a digital matrix, and you reverse it. Uh... it's a bit difficult, can you imagine?"

Su Yun glanced at Zheng Ren, and said contemptuously, "You mean that the digital matrix passes through a digital converter to convert each number into black, white, and gray pixels, and arrange them in a matrix?"

This is the basic principle of CT imaging, of course Su Yun understands it. But if it's the other way around... what do you get?

"If you know it, try it. In turn, get the most original data, and then transform it again according to 64-slice CT three-dimensional imaging."

"..." Su Yun was stunned.

This transformation is to treat the human brain as a machine, and it is still a high-frequency machine.

Is this something humans can do?

The arrogance in his eyes turned into countless doubts, and he was speechless for a long time looking at the film inserted in the film viewer.

Director Chen also followed after arranging the work of the nurses.

He was very curious about how Zheng Ren made the diagnosis.

As an old imaging worker, when Director Chen was young, the hospital imported a machine, and he had to repair it himself if it broke down.

So what Zheng Ren said, he understood more thoroughly than Su Yun.

It's just... that's okay?

"Doctor Zheng, have you constructed a 64-slice CT three-dimensional imaging in your brain?" Director Chen asked suspiciously.

"It's not that exaggerated." Zheng Ren said with a smile: "It would be difficult to reconstruct all the data. But if we only limit ourselves to this point, there will be much less data to reconstruct, which is relatively simple."

Director Chen thought to himself, is it so powerful? In my opinion, it is absolutely impossible to do it, but Dr. Xiao Zheng only said it was difficult, not completely impossible!

"I understand!" Su Yunmeng slapped the table in front of the film reader and said loudly, "Here is a vascular intima fault!"

"Yes." Zheng Ren said: "When injured, the blood pressure rose instantly and the intima of the blood vessel ruptured. However, the blood pressure dropped immediately due to massive bleeding, and there was no major problem with the intima of the blood vessel. After the intervention, The blood vessels that were bleeding were all embolized, and the patient's blood pressure gradually increased, which caused the rupture of the intima of the abdominal aorta to start tearing again."

"Boss, I remember you knew it after just a glance." Su Yun was a little puzzled, the diagnosis was not a problem, and he even thought that what Zheng Ren said was nonsense.

The key point is that Zheng Ren restores the CT images to the original data and then reconstructs them. This speed is simply too fast!

Moreover, Su Yun's biggest doubt was not asked. That is—how did Zheng Ren judge that there was a problem with that point.

Zheng Ren pointed out the location, and he had to do mental calculations for a long time before restoring and rebuilding. And this guy, when he brought the film, he casually said that he needed emergency surgery.

What a monster, Su Yun muttered in his heart.

"I've watched a lot of movies, and I feel it." Zheng Ren said casually.

Although Director Chen knew it, but he was too old, and his brain power was no longer able to do such complicated calculations as he did when he was young.

According to the normal process, the patient needs to be taken to the CT room for vascular CTA examination, and then the diagnosis can be made. After the diagnosis is made, the operation sheet is raised and a stent is placed in the patient's abdominal aorta to solve the problem.

Before interventional surgery, aortic dissection was a serious disease, a fatal one. With interventional surgery, as long as it can be diagnosed, except for type 1 aortic dissection, it is a minor problem.

As long as the angiography is involved, the location of the arterial dissection can be seen on the image, and there is no need for three-dimensional reconstruction of blood vessels.

But this needs to be established on the basis of correct diagnosis.

Old Director Chen hesitated.
