Doctor: I picked up attributes in the hospital

Chapter 383 Expensive high-intensity magnetic field superconducting nuclear magnetic resonance instrument
After leaving Gao Jun's office, Zhao Heng returned to the ward.

We will arrive at Yenching University in the afternoon, so we can take a break at noon.

Although it was said that Gao Jun was handling various relationships behind him, Zhao Heng still felt that the personnel relationship was really too complicated.

It is obviously a very simple thing, but now it is so complicated.

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

At this moment, Ruan Liuzheng, who had finished writing the medical records, came to the office. Seeing Zhao Heng coming back, 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 comprehensive university with a ceiling level in China.

"In the afternoon."

Zhao Heng took a sip of coffee and said.

"Then I'll go get ready."

Ruan Liuzheng went on to say that for [-]D scanning or something, she also had a blind eye, which was considered a blind spot in her knowledge, and she still needed to check the information to prepare, so as not to waste such a good opportunity.

"Don't be so nervous, just go to do a three-dimensional scan for the patient. At most, the equipment is more advanced. Drink a cup of coffee and take a break."

Zhao Heng said casually.

Ruan Liuzheng, as a student, is fine, but it's a bit too tense. Sometimes it's not good to be too tense in this job, and you have to learn to relax properly.

"Row."

Ruan Liuzheng nodded without being shy.

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

"Teacher, is something not going well?"

Seeing the dark 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 strong empathy, so she can detect even a little 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.

In fact, Ruan Liuzheng always keeps a respectful distance from people who don't like them a little bit.

"Things are going well."

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

Well, coffee tastes good only if it tastes a little bit bitter. It's like life. When you think about it, most of them are all kinds of bitterness.

"So the teacher thinks that interpersonal relationships are too complicated?"

Ruan Liuzheng said tentatively.

She has always been able to accurately know the emotional changes of others, 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. Ruan Liuzheng seemed to know what he was thinking and what was bothering him. Ruan Liuzheng's intuition, or empathy ability, was too powerful.

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

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

Ruan Liuzheng said with a smile.

Regardless of her appearance as a sweet girl, Ruan Liuzheng's heart is far stronger than most people.

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

Zhao Heng looked at Ruan Liuzheng, who had a sweet girl's face, and said.

Everyone has their strengths. Zhao Heng's strengths are naturally technical. As for interpersonal relationships, he can only speak of mediocrity.

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

Yenching University School of Medicine.

Medical 3D reconstruction [-]D 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 undergo a deep body scan with a strong magnetic field.

Ruan Liuzheng and Jiang Rui naturally stood behind them as followers.

Looking at the high-intensity magnetic field superconducting nuclear magnetic resonance instrument with a cost of more than 1 million yuan and a magnetic field strength of 7.0T, Zhao Heng sighed a little. Such a large-scale equipment is really too expensive, and it may be difficult for ordinary large hospitals to equip it. .

This nuclear magnetic resonance is a physical process in which the atomic nucleus whose magnetic moment is not zero undergoes Zeeman splitting in the spin level under the action of an external magnetic field, and resonantly absorbs a certain frequency of radio frequency radiation.

The working principle of nuclear magnetic resonance is to generate nuclear spin through hydrogen nuclei in water molecules or fat molecules, resulting in the appearance of magnetic moments. Nuclear magnetic moments can cause moving nuclei in a static external magnetic field, thereby causing energy level splitting, coupled with the effect of alternating magnetic fields , the spin nucleus absorbs electromagnetic waves of a specific frequency, and the low energy level can transition to a high energy level to generate a signal.

After that, the linear gradient of the magnetic field is used to locate and collect the signal. The magnet, gradient system and radio frequency system are connected with the computer system to realize communication between different electronic components and perform complex interactions, and finally the nuclear magnetic resonance image can be formed .

Therefore, nuclear magnetic resonance imaging is an examination method that uses computers to analyze and diagnose images of human body sections. It does not use X-rays, but magnetic fields. The basic principle is that hydrogen atoms contained in the human body will resonate after being given specific high waves under a strong magnetic field. , producing an electromagnetic wave with a high wave number.

It is precisely because of this that MRI has no damage 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."

Looking at the inside of the operating room, Huang Jincheng couldn't help but sighed at the clear three-dimensional picture displayed with the depth scan.

Modern medicine is actually highly dependent on new technologies.

For example, for this patient, what Zhao Heng and Huang Jincheng did was to perform a deep three-dimensional scan on the patient, and then use VR to pre-simulate the upcoming operation. By browsing the patient's MRI and 3D view, you can Knowing what to expect during surgery can reduce risk and increase the success of surgery.

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

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

In fact, hospitals nowadays are generally short of money, although in large hospitals, MRIs worth tens of millions are basically standard equipment.

But in fact, most of these tens of millions of instruments are not bought by hospitals.

Generally speaking, it is to introduce external capital to purchase such a large-scale instrument, and then share the proceeds.

There is no other way to do this. If the hospital spends so much money to purchase such a large-scale instrument, it will have no funds to do other things such as rebuilding the campus.

"You get what you pay for."

Jin Cheng said with a little emotion.

A piece of equipment worth more than 1 million yuan is naturally different from an ordinary MRI with a cost of 2000 million yuan.

Ordinary nuclear magnetic resonance, how can scan such a clear three-dimensional image.

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

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

Having said that, readers, you should be able to understand the importance of resource allocation for hospitals and doctors!
Because there are some things that doctors or even hospitals alone cannot handle.

Half an hour later, Zhao Heng and Huang Jincheng looked at the scanned [-]D imaging and were even more amazed. How can I put it this way? Hang the same.

"May I ask, is this imaging software a supporting development?"

Zhao Heng suddenly asked the technical researcher sitting on the console.

Seeing such a clear and detailed 4.0D imaging, Zhao Heng was immediately moved by this set of equipment, but this equipment is currently unavailable in hospitals, but this imaging software is not so expensive. If you can buy a set It is also possible to use it in general [-]T field strength NMR.

Although the final three-dimensional imaging level is not up to the research level seen now, it is enough for surgery.

"No, this set of imaging software is 3D-DOCTOR software, which was developed by Able Software. Currently, it is a relatively advanced three-dimensional modeling, image processing and measurement software in the world."

The researcher pushed the glasses frame and said very strictly.

"That is to say, this set of software can be purchased separately, and can also be used on other MRI machines or other inspection equipment?"

Zhao Heng grasped the point of the researcher very keenly, and asked again.

"Theoretically, it does."

The researcher nodded.

"How much does this imaging software cost?"

Before Zhao Heng opened his mouth, Huang Jincheng asked first.

"This set of imaging software can be used in many fields, such as MRI, CT\PET, microscopy images, and image processing in industrial fields. The usage fee is about 100 million per year."

The researcher thought for a while and said seriously.

A set of software for multi-field purposes naturally has a wide range of adaptability, so the price of a single set is not expensive, after all, small profits but quick turnover.

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

"If it's 100 million, it's okay."

Jin Jincheng pondered for a while and said.

After Zhao Heng heard this, he felt a little uncomfortable. The domestic medical software anesthesia assistant developed by him and Wang Yaoqing is relatively good, but the annual usage fee is only about 20, and this set of 100 million software, That's a five-fold difference.

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

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

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

At this point, it was already off-duty time, and Zhao Heng didn't have to work the night shift, so he could go home.

However, at this point in time, Xu Manni had already returned home, and her parents had just returned, so Xu Manni always went back to her parents' house.

According to Zhao's father and Zhao's mother, they are probably also 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 beside him waiting for the bus.

"Teacher, do you want to have dinner together?"

Seeing Zhao Heng looking at himself, Ruan Liuzheng asked with a smile.

"You are really a prophet..."

Zhao Heng said with a strange expression.

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

It was the first time Zhao Heng met someone with such a terrifying intuition. Presumably a master of psychology like Gao Qilan would be very interested in someone like Ruan Liuzheng.

"Usually I don't show it, or people won't like it."

Ruan Liuzheng said straightforwardly.

There is a marginal space for people to communicate with each other. After all, no one likes to be seen through their minds.

"Then you still show it in front of me?"

Zhao Hengrao asked with great interest.

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

"Teacher, you don't care about these kind of frank people."

Ruan Liuzheng said very seriously.

Really powerful people are not afraid of being seen through their minds, or in other words, real masters all play open cards and use ulterior motives.

"I know a master psychologist, she must like you very much."

Zhao Heng said with a smile.

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 casually ordered a few dishes, and now he was waiting for the dishes to be served.

"It's been a long time since I felt this relaxed feeling."

Ruan Liuzheng suddenly sighed and said that since she went to medical school, whether she was going to school or after graduation, she felt like a clockwork was being wound up all the time, and there was no easy time for her.

"Being a doctor is very hard. You can choose other industries. Even now, if you consider changing careers, there is still time."

Zhao Heng said casually.

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

After all, medical-related jobs are not just for doctors.

In the simplest terms, many medical schools actually need teachers.

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

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

Ruan Liuzheng said with a smile.

She was telling the truth. If it weren't for dreams, most people wouldn't be able to persist in a profession like a doctor whose investment and output are completely disproportionate.

Let’s talk about Ruan Liuzheng. After she graduated from graduate school, she found that more than half of her classmates who were in clinical undergraduate studies together did not become doctors anymore.

"Do you want to stay in the hospital?"

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

"Of course I want to, who in this group doesn't want to."

Ruan Liuzheng said without hesitation.

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

"Then work hard."

Zhao Heng encouraged Ruan Liuzheng and said.

Although he already felt that Ruan Liuzheng was not bad, he still wanted to take another look.
