Coming out of Gao Jun's office, Zhao Heng returned to the ward.

When you get to Yenching University, it will be in the afternoon, so you can take a little break at noon.

Although it is said that Gao Jun is dealing with various relationships in the back, Zhao Heng still feels that this personnel relationship is really too complicated.

It's a very simple thing, but now it's so complicated.

Sitting on the sofa in the deputy director's office, Zhao Heng made himself a cup of coffee and drank handmade mellow coffee, Zhao Heng's mood was a little better.

At this time, Ruan Liuzheng, who had finished writing the medical record, came to the office and saw that Zhao Heng was back, and Ruan Liuzheng walked in.

"Teacher, when are we going to Yenching University?"

Ruan Liuzheng looked at Zhao Heng and asked.

Ruan Liuzheng is still looking forward to going to Yenching University, after all, it is a ceiling-level comprehensive university in China.

"Afternoon."

Zhao Heng took a sip of coffee and said.

"Then I'll go get ready."

Ruan Liuzheng continued, for three-dimensional scanning or something, she is also black-eyed, which is considered a blind spot in her knowledge, and she still has to check the information and prepare, so as not to waste such a good opportunity.

"Don't be so nervous, just go and do a 3D scan of the patient, at most the equipment is more advanced, drink a cup of coffee and take a break."

Zhao Heng said casually.

This Ruan Liuzheng, as a student, that's nothing, but it's a little too tight, this work, sometimes it's not good to be too nervous, and you have to learn to relax properly.

"Okay."

Ruan Liuzheng nodded, and he was not embarrassed.

Soon, Ruan Liuzheng made himself a cup of coffee, sat on the sofa on the other side, took a sip of coffee, and looked at Zhao Heng again.

"Teacher, is things not going well?"

Seeing a little hazy feeling between Zhao Heng's eyebrows, Ruan Liuzheng couldn't help asking.

She is the kind of girl who is as careful as a hair and has a very strong empathy, so she can detect the slightest change in other people's emotions.

It is because of this that everyone who has been with her thinks that she has a good temper and character.

In fact, for the kind of people who don't like it a little, Ruan Liuzheng is respectful.

"Things are going well."

Zhao Heng said casually and continued to take a sip of coffee.

Well, coffee is only good to taste a little bitter, it's like life, if you taste it in retrospect, most of it is all kinds of bitterness.

"That is, the teacher thinks that interpersonal relationships are too complicated?"

Ruan Liuzheng said tentatively.

She has always been able to know other people's emotional changes very accurately, and the reason for the emotional changes is also a guess, maybe this is a very special talent.

"How do you know?"

Zhao Heng was a little surprised, he didn't say anything, this Ruan Liuzheng seemed to know what he was thinking and worrying about, this Ruan Liuzheng's intuition, or empathy ability, was too powerful.

In contrast, many people's hearts are numb and dull like rotten wood.

"I've known this since I was a kid."

Ruan Liuzheng said with a smile.

Don't look at the appearance of a sweet girl, Ruan Liuzheng's heart is far more powerful than most people.

"It seems that the job of a doctor can give full play to your strengths."

Zhao Heng looked at Ruan Liuzheng with a sweet face and said.

Everyone has everyone's strengths, Zhao Heng's strengths are naturally technical, as for interpersonal relationships or something, he can only say average.

The time came to three o'clock in the afternoon.

Yenching University School of Medicine.

Medical 3D Reconstruction 3D Printing Innovation Teaching Center.

At this moment, Zhao Heng and Huang Jincheng were standing in the observation room of the MRI room, watching the mother do a deep full-body scan with a strong magnetic field inside.

And Ruan Liuzheng and Jiang Rui naturally stood behind the two as followers.

Looking at the high-strength magnetic field superconducting nuclear magnetic resonance instrument in front of him, which costs more than 100 million yuan and has a magnetic field strength of 7.0t, Zhao Heng sighed a little, such a large-scale equipment is too expensive, and it is difficult to equip ordinary large hospitals.

This nuclear magnetic resonance is a physical process in which the spin level of an atomic nucleus with a magnetic moment of non-zero is split by Zeeman under the action of an external magnetic field, and the resonance absorbs a certain frequency of radio frequency radiation.

The working principle of nuclear magnetic resonance is to produce nuclear spin through the hydrogen nuclei in water molecules or fat molecules, resulting in the occurrence of magnetic moments, which can cause moving nuclei in the stationary external magnetic field, thereby causing energy level splitting, coupled with the effect of alternating magnetic field, spin nuclei absorb electromagnetic waves of a specific frequency, and low energy levels can jump to high energy levels to produce signals.

The linear gradient of the magnetic field is then used to locate and acquire the signal, and the magnet, gradient system, and radio frequency system are connected to the computer system to communicate between different electronic components, and the complex interaction can be carried out to form an MRI image.

Therefore, MRI is an examination method that uses a computer to analyze and diagnose the image of the human body, it does not use X-rays, but a magnetic field, and its basic principle is that the hydrogen atoms contained in the human body will resonate after giving a specific high wave under a strong magnetic field, producing a high wavenumber of electromagnetic waves.

Because of this, MRI is not harmful to the human body and is a non-invasive examination.

"Xiao Zhao, such a device can be said to be of great help to surgeons."

Huang Jincheng looked at the inside of the operation room, with the clear three-dimensional picture displayed by the deep scan, and couldn't help but sigh a little.

Modern medicine, in fact, is highly dependent on new technologies.

For example, for this patient, what Zhao Heng and Huang Jincheng did was to first conduct a deep 3D scan of the patient, and then use VR to simulate the upcoming operation in advance, and by browsing the patient's MRI and 3D views, they can understand what will happen during the operation, so as to reduce the risk and improve the success rate of the operation.

"It's good, it's just too expensive."

Zhao Heng nodded, such an instrument, for surgeons, is like a magic weapon used by heroes in martial arts, and it has a great bonus to the success rate of surgery.

In fact, today's hospitals are generally short of money, although in large hospitals, tens of millions of MRIs are basically standard.

But in fact, most of the instruments that cost tens of millions of dollars are not funded by hospitals.

Generally speaking, it is the introduction of external capital to buy such a large instrument and then share the benefits.

There is no way to do it, if the hospital spends so much money on such a large instrument, there is no money to do other things such as renovating the hospital.

"You get what you pay for."

Huang Jincheng said with a little emotion.

The equipment of more than 100 million units is naturally different from the ordinary nuclear magnetic resonance that costs 10 million or 20 million.

How can an ordinary MRI scan such a well-structured three-dimensional image?

Although doctors at the director and deputy director levels like Huang Jincheng and Zhao Heng are among doctors, their income is already at the ceiling level.

But this kind of income is still far from this kind of high-end medical equipment that can easily reach hundreds of millions.

Speaking of which, readers should be able to understand the importance of resource allocation for hospitals and doctors!

Because there are some things that can't be done by doctors or even hospitals alone.

Half an hour later, Zhao Heng and Huang Jincheng looked at the three-dimensional imaging that had been scanned, and they were even more amazed, how to say it, it was simply exquisite, if you did surgery according to this model, it could be said that it was directly like opening a perspective hanging.

"I would like to ask, is this imaging software developed in a supporting way?"

Zhao Heng suddenly asked the technical researcher sitting on the operating table.

Seeing such a clear and delicate three-dimensional imaging, Zhao Heng was suddenly a little moved by this set of equipment, but this equipment is currently unaffordable in hospitals, but this imaging software is not so expensive, if it can be used in a set, it can be used in general 4.0t field strength nuclear magnetic resonance.

Although the final level of 3D imaging is not up to the level of research seen so far, it is enough for surgery.

"No, this set of imaging software, is 3D-Doctor software, developed by Able Software, at present, the most advanced 3D modeling, image processing and measurement software in the world."

The researcher pushed the frame of his glasses and said very seriously.

"In other words, this set of software can be purchased separately and can also be used on other MRI machines or other examination equipment?"

Zhao Heng was very keen, grasped the point of what the researcher said, and asked again.

"That's the way it is, in theory."

The researcher nodded.

"How much does this imaging software cost?"

Before Zhao Heng could speak, Huang Jincheng asked first.

"This set of imaging software can be used in many fields, such as MRI, CT\PET, microscopy technology images and industrial image processing, and the usage fee is about one million per year."

The researcher thought for a moment, and said very seriously.

A set of multi-field software has a wide degree of adaptability, so the price of a single set is not expensive, after all, small profits and quick turnover.

If it is used alone for medical image processing, it will be several times more expensive.

"A million, that's okay."

Huang Jincheng said with a deep groan.

Zhao Heng listened, but he felt a little uncomfortable in his heart, the domestic medical software anesthesia assistant developed by him and Wang Yaoqing is relatively good, but the annual usage fee is only about 200,000, and this set of one million software, that is a five-fold gap.

However, this set of imaging software can be applied to imaging in many fields, and in terms of technical strength, it is still higher than the anesthesia assistant developed by Zhao Heng and Wang Yaoqing.

After all, the software of anesthesia assistant is essentially a clinical database, and then it is an analysis and judgment module, which is very innovative in terms of creativity, but in fact, the technology is not much innovative.

Next, the patient was sent back to the hospital, and Zhao Heng also came out of Yenching University, and when he looked at the time, it was already six o'clock in the afternoon.

At this point, it is already off-duty time, and Zhao Heng does not have to work the night shift, so he can go home.

However, at this point in time, Xu Manni has already gone home, and her parents have just returned, so Xu Manni is back to her parents' house.

Zhao's father and Zhao's mother's words are estimated to be in the noodle shop, and they have already eaten at this point.

After thinking about it, Zhao Heng looked at Ruan Liuzheng who was standing next to him waiting for the car.

"Teacher, would you like to have dinner together?"

Seeing Zhao Heng looking at himself, Ruan Liuzheng smiled and asked.

"You really are a prophet of the unknown.

”

Zhao Heng said with a somewhat strange expression.

He didn't say it yet, just glanced at Ruan Liuzheng, and she knew what it meant, it was really interesting.

With such a terrifying intuition, Zhao Heng is the first time he has encountered it, presumably a psychology master like Gao Qilan should be very interested in someone like Ruan Liuzheng.

"Normally, I don't show it, otherwise others won't like it."

Ruan Liuzheng said very bluntly.

There is a marginal space for people to interact with people, after all, no one likes to be seen through their minds.

"And you're still showing it in front of me?"

Zhao Heng asked with interest.

I have to say that this Ruan Liuzheng is a very interesting person, and her heart does not match her appearance at all.

"Teacher, you don't care about these things for a frank and unscrupulous person."

Ruan Liuzheng said very realistically.

Really powerful people are not afraid of being seen through their minds, or in other words, the real masters are all playing cards and using yang schemes.

"I know a master of psychology, and she must like you very much."

Zhao Heng smiled and said.

Ten minutes later, in a restaurant next to Yenching University, Zhao Heng and Ruan Liuzheng sat face to face at a table by the window.

Zhao Heng ordered a few dishes very casually, and now it was the time to wait for the dishes to be served.

"It's been a long time since I've felt this kind of relaxation."

Ruan Liuzheng suddenly said with a sigh that since she went to medical school, whether it was going to school or graduating and working, she felt like she had been wound up all the time, and there was no moment of relaxation.

"It's hard to be a doctor, you can choose other professions, even now, if you want to think about changing careers, it's too late."

Zhao Heng said casually.

Ruan Liuzheng is very smart, which he can see, even if Ruan Liuzheng has graduated from clinical graduate school now, he can actually choose not to be a doctor.

After all, medicine-related work is not only for doctors.

To put it simply, many medical schools actually need teachers.

There are also medical journals, medical device companies, etc., which also need medical professionals.

"Becoming a doctor has been my dream since I was a child, and no matter how hard it is, I will persevere."

Ruan Liuzheng said with a smile.

She is telling the truth, if it weren't for her dreams, ordinary people would not be able to persevere in a profession like a doctor, where the input and output are completely disproportionate.

Let's talk about Ruan Liuzheng, after she graduated from graduate school, she found that most of the classmates who studied clinical undergraduates together at the beginning were not working as doctors.

"Do you want to stay in the hospital?"

Zhao Heng looked at Ruan Liuzheng with firm eyes, and suddenly asked.

"Of course I think so, who doesn't want this batch."

Ruan Liuzheng said without hesitation.

There is nothing to hide in this kind of thing, and now the competition is also on the surface.

"Then let's do our best."

Zhao Heng encouraged Ruan Liuzheng and said.

Although he already thinks that Ruan Liuzheng is not bad now, he still wants to see it again.
