Chapter 737: 726 Data Primitive Reconstruction, Then Rebuild

726 Data Primitive Reconstruction, Then Rebuild

"Huh?" Director Chen stared for a moment.

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

In the ruins of Nanchuan Town, a life‑or‑death surgery let him touch a major bottleneck in technique, and unintentionally break those shackles.

Although it was only temporarily evident in surgery, Zheng Ren knew his film‑reading ability had surely undergone a huge change.

When doing surgery at Pengxi Township Hospital, every time he saw a patient's X‑ray, related information would involuntarily surface in his mind.

If it weren't for the front line, with countless wounded awaiting treatment, Zheng Ren would have long been unable to resist his curiosity to ponder it.

At this moment, facing a patient with abdominal pain, the CT film Zheng Ren saw and the fragments appearing in his mind were not the same.

The CT film was simplified into data, then merged in his mind, becoming exactly what Zheng Ren wanted.

Because Zheng Ren had seen the patient's diagnosis, the workload of doing all this was not great; he immediately located the abnormal spot on the film and pinpointed the problem.

Looking at the CT film before him, there was only a tiny, vague abnormality; if not carefully examined, it would be an ordinary CT of a retroperitoneal hematoma. That slight abnormality could be judged as a fat shadow or an artifact.

However, Zheng Ren now sees the CT film as something quite different.

Su Yun leaned over, frowned, and asked, "Boss, I think this film is fine."

Director Chen also found it strange, but he said nothing. His experience in Nanchuan Town had made him realize this young doctor was special; otherwise he wouldn't have called Zheng Ren over specially.

"Su Yun, look…" Zheng Ren said, then suddenly recalled something and immediately said, "Director Chen, micro‑pump, lower the pressure, control the patient's blood pressure. The patient is in severe pain; first give 5 mg morphine."

Zheng Ren spoke politely, but his confident expression and tone that brooked no refusal were exactly the bearing of a senior doctor.

Director Chen, though doubtful, did not refuse. He immediately called a nurse, who first gave 5 mg morphine as Zheng Ren instructed, then set up a micro‑pump to infuse sodium nitroprusside intravenously to control blood pressure.

Now the patient cannot be moved, and Zheng Ren can do nothing about it despite his anxiety.

Although the blood pressure on the ECG monitor is not high, there remains a possibility that moving the patient could cause a sudden spike, rupturing the abdominal aorta.

We must first control the blood pressure.

This is similar to when I first went to Du Du and, on the plane, foresaw Cui Heming's thoracic aortic dissection.

But now we have micro‑pumps and various drugs, so everything is far better than the conditions on that plane before.

Seeing that side was busy and wouldn't be ready for surgery anytime soon, Su Yun wouldn't let go, grabbing Zheng Ren and asking, "How did you see that? Anyway the patient can't be moved for now—tell me quickly."

Zheng Ren nodded, picked up the film, and walked to the doctors' office.

The viewer was lit, with two films inserted into it.

Zheng Ren tidied the films inserted in the viewer, found the appropriate sleeve by the time and name in the upper‑right corner, then inserted the abdominal CT of the patient with abdominal pain into the viewer.

"Look here carefully," Zheng Ren said. "It looks normal, like a normal vascular structure. But don't you feel the density differs from the surrounding vessels?"

He pointed to a spot on the film and said firmly.

Su Yun stared at the spot Zheng Ren was pointing at, his expression strange.

"It's like this: you arrange the pixels according to a numeric matrix, then reverse it. Uh… it's indeed a bit hard—can you imagine that?"

Su Yun glanced at Zheng Ren contemptuously and said, "You mean the numeric matrix goes through a numeric converter, turning each number into a pixel ranging from black to white, not equal grayscale, and then arranged according to the matrix?"

This is the basic principle of CT imaging; Su Yun of course understands it. But if you reverse it… what do you get?

"If you know, give it a try: reverse it to obtain the most primitive data, then reconstruct it three‑dimensionally with a 64‑slice CT, and transform it once more."

"……" Su Yun froze.

Doing this transformation is like using the human brain as a machine—and a high‑frequency one at that.

Can a person actually do that?

The arrogance in his eyes turned into countless doubts as he gazed at the film inserted in the viewer, remaining silent for a long time.

After Director Chen had finished arranging the nurses' work, he also came over.

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

As an veteran imaging worker, when Director Chen was young the hospital imported a machine that, whenever it broke, he had to repair himself.

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

But… would that even work?

"Doctor Zheng, are you constructing a 64‑slice CT three‑dimensional reconstruction in your own brain?" Director Chen asked doubtfully.

"Not that exaggerated," Zheng Ren laughed. "If we had to reconstruct all the data, it would be very difficult. But if we limit ourselves to just this point, the amount of data to rebuild is much less, making it relatively simple."

Director Chen thought, "Is it really that powerful? In my view it's absolutely impossible, yet little Doctor Zheng merely says it's hard, not that he can't do it at all!"

"I get it!" Su Yun slammed his hand on the table before the viewer and shouted, "Here, there is a vascular intimal layer tear!"

"Yes," Zheng Ren said. "When injured, blood pressure spikes instantly, causing a rupture in the vascular intima. But immediately, massive bleeding drops the pressure, so this segment of intima doesn't suffer major problems. After the interventional procedure, the bleeding vessels are embolized, the patient's blood pressure gradually rises, and that causes the tear in the abdominal aortic intima to start ripping again."

"Boss, I remember you glanced at it and just knew." Su Yun had some doubts; the diagnosis was fine, and he even thought Zheng Ren's lengthy explanation was just nonsense.

The key point is that Zheng Ren restores the CT image to raw data and then reconstructs it—this speed is simply too fast!

Moreover, Su Yun's biggest doubt remained unasked: namely, how Zheng Ren judged that point to be problematic.

Zheng Ren pointed out the location; even he himself would need a long mental calculation to restore and reconstruct it, while this guy, after taking the film, casually said they needed emergency surgery.

Damn, what a monster, Su Yun muttered to himself.

"Just from looking at many films, I have a feel for it," Zheng Ren replied offhand.

Director Chen knew, but he was too old; his mental capacity could no longer handle such complex calculations as when he was young.

Following the normal procedure, one must take the patient to the CT room for a vascular CTA scan, then confirm the diagnosis. After confirmation, issue a surgical order and place a stent in the patient's abdominal aorta to solve the problem.

Before interventional surgery existed, aortic dissection was a major, life‑threatening disease. With interventional surgery, as long as you can diagnose it, everything except type 1 aortic dissection becomes a minor problem.

As long as you perform interventional angiography, the location of the aortic dissection can be seen on the image, and there's no need to do a three‑dimensional reconstruction of the blood vessel.

But this presupposes that the diagnosis is correct.

Director Chen began to hesitate.
