Chapter 155: 0152 Private Customization (Middle)

Zheng Ren rubbed his face, making his smile look more amiable.

No matter how you put it, he was coming to ask for a favor; although he was using Su Yun's face, losing face would be losing Su Yun's, but… being too stern was never good.

"Sister Zhao." Zheng Ren pretended not to hear Sister Zhao's nagging, entered the CT room's control area, a rare smile on his face, startling Su Yun and Chang Yue.

"Chief Zheng, I'm not saying this about you." Sister Zhao lowered her voice a lot, after all you don't hit a smiling face, but the nagging still had to be nagged.

"You say, you say." Zheng Ren put on a pose of not fighting back, not talking back.

"CT 3D reconstruction is a highly difficult operation; our hospital bought the machine when it was founded, yet no one figured it out." Sister Zhao operated the machine while examining Zheng Yunxia, chattering away, doing two things at once, "Later the hospital sent three batches for training; I studied a whole year before I barely got a handle on it."

"Yes, yes." Zheng Ren wore a smile, completely unembarrassed.

"You say you want to do 3D reconstruction?" Sister Zhao grew increasingly unhappy, "Have you studied it?"

"Just watching you operate once, I wanted to try."

Su Yun: "……"

Damn it, this is what I often say!

"……" Sister Zhao was speechless, silent for a while, then said: "The machine is too expensive to let you play around with it. I'll watch; if anything's wrong, I'll refuse."

"Of course." Zheng Ren kept his low profile as always.

These days, asking someone for help is really hard. Zheng Ren knew Sister Zhao's difficulty; if she asked him to say she could do surgery, to do an appendectomy, he'd probably slap her away.

Even though Su Yun had already proved his ability, Zheng Ren was unwilling to let him do it easily. It wasn't about suppressing the young…

It's not certain who's younger. It's just that because his surgeries are better, Zheng Ren insists on personally handling every special case.

"Half an hour." Sister Zhao finally said.

"Sister, half an hour isn't enough." Zheng Ren said: "A routine 3D reconstruction takes half an hour per patient. I need to do reverse 3D reconstruction, which requires at least two hours."

"!!!" Sister Zhao turned, giving Zheng Ren a sideways glance.

What the hell is this guy talking about? Reverse 3D reconstruction? What the heck is that?

"It's a method where, based on 3D reconstruction, you locate the abnormally proliferating blood vessels, then retrograde search for the weak, abnormal vascular signals to reconstruct." Zheng Ren gave a brief explanation, seeing Sister Zhao's grim expression, he quickly added: "Sister, you don't know—last surgery, the tumor's feeding vessel had a branch coming off the diaphragmatic artery; I stood in the operating room wearing dozens of pounds of lead clothing for four full hours before I found it."

Sister Zhao was moved.

Although Zheng Ren's words were a bit exaggerated, they were basically true. Su Yun was about to retort, but Zheng Ren's complaining held him back.

"Do you really know how?" Sister Zhao recalled Zheng Ren's words; although she hadn't seen it, she thought she could do it. Only the required time… that's a huge amount of computation.

It's not that the CT staff don't want to do it; the 64‑slice machine is extremely expensive, and the core technology of the operating software is held by multinational corporations. Even if the hospital were rich, it absolutely couldn't splurge on buying ten or eight software packages.

Even if they bought it, doing a reverse 3D reconstruction would take several hours, and there simply aren't enough personnel to spare.

So this is just a special case—a situation that even a senior CT deputy chief like Sister Zhao has never encountered.

"Then go ahead and try." Sister Zhao's curiosity finally won out; she stopped being angry and voluntarily agreed.

Half an hour later, Zheng Yunxia's examination was finished, the routine reconstruction done. Sister Zhao stepped aside, and Zheng Ren took the console.

"Little Su, does he really know?" Sister Zhao still didn't believe it; although Zheng Ren spoke fluently, who doesn't understand theory? Reading a few books lets you spout a whole set of theory. Only when you actually operate does it become the real test.

"I really don't know." Su Yun gave a wry smile, "At Xiehe I've never seen anyone do 3D reconstruction themselves, let alone reverse 3D reconstruction."

"If you say you're a thief, I was still wondering why you ran to the Emergency Department—turns out you've got a thick thigh to cling to." Sister Zhao teased.

"Sister, I myself am that thick thigh; I don't need to cling." Su Yun brushed back his forehead hair.

"If he really can do it, that would be awesome. With this skill plus surgery, going to a private hospital in the south, forget a million‑year salary—even five‑million‑a‑year would have takers, and it'd be after tax." Sister Zhao felt a twinge of envy.

This spring she had also wanted to quit. Using paid leave, she toured southern hospitals, sent out a few résumés, so she knew the market.

But because her lover had a cerebral hemorrhage, the plan to quit and go south was put on hold.

That didn't stop her from knowing what kind of technical talent is valued in the south and what salary it commands.

Zheng Ren's hands danced across the console, skilled as hell.

If you didn't know his background, you'd think he was a CT department head from some hospital showing off his technique.

Su Yun also felt a bit dazed—how could Zheng Ren know CT 3D reconstruction? When did he learn it?

From the moment Zheng Ren began operating, the initially reconstructed liver on the screen started to rotate; Sister Zhao stopped talking and stared intently at the images.

In her mind she was guessing the significance of each of Zheng Ren's steps.

As for the earlier worry that Zheng Ren might break the machine, that had long been forgotten.

His technique is pure; breaking it? Sister Zhao guessed that if the machine broke, this Emergency Department Chief Zheng would fix it himself.

In the images, Zheng Yunxia's liver, after interventional surgery treatment, was already fully controlled. The periphery of the nearly ten‑centimeter tumor had necrosed and fibrosed, but because the tumor was large, Zheng Ren hadn't embolized it too heavily.

If it were completely necrotic, the tumor interior would liquefy, seriously leading to sepsis or bacteremia; even necrotic tissue could corrode surrounding tissue, and once a small vessel corroded and ruptured, bleeding would be life‑threatening.

The tumor diameter shrank to about five centimeters, achieving effective control.

But Zheng Ren seemed unsatisfied, still searching frame by frame.

Ten minutes…

Twenty minutes…

One hour…

Su Yun grew tired; even with his high talent, lacking any 3D reconstruction training, he couldn't tell what Zheng Ren was looking for.

Not to mention Su Yun—even Sister Zhao couldn't follow Zheng Ren's operation.

The frames filtered one by one, occasionally rolling back, pulling up the raw data, glancing at it, then continuing downward.

What the hell is he doing?!
