Doctor: Picking Up Attributes in the Hospital-Chapter 462 - 382: Expensive High-Field Superconducting MRI Scanner

Chapter 462: Chapter 382: Expensive High-Field Superconducting MRI Scanner

After coming out of Gao Jun’s office, Zhao Heng returned to the ward.

The visit to Yanjing University is scheduled for the afternoon, so he could take a brief rest at noon.

Although Gao Jun was handling various relationships behind the scenes, Zhao Heng still felt that personnel relationships were indeed too complicated.

Clearly a very simple matter had become unbelievably complex.

Sitting on the sofa in the associate director’s office, Zhao Heng brewed himself a cup of coffee. Drinking the freshly made aromatic coffee, he felt slightly better.

At this moment, Ruan Liuzheng came to the office after finishing her medical records. Seeing Zhao Heng was back, she walked in.

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

Ruan Liuzheng asked Zhao Heng.

She was quite looking forward to going to Yanjing University, after all, it’s a top-tier comprehensive university in the country.

"In the afternoon."

Zhao Heng said after taking a sip of coffee.

"Then I’ll go get prepared."

Ruan Liuzheng continued, considering the three-dimensional scans and such were quite unfamiliar to her. This was a blind spot in her knowledge, so she wanted to look up some information to prepare and not waste such a good opportunity.

"Don’t be too tense, it’s just going to do a three-dimensional scan for a patient. At most, the equipment is advanced, so have a cup of coffee and relax."

Zhao Heng casually remarked.

As a student, Ruan Liuzheng was impeccable, but she was a little too uptight. Sometimes, being overly tense at work is not good; one must learn to relax appropriately. 𝙛𝓻𝒆𝒆𝒘𝙚𝓫𝙣𝙤𝒗𝙚𝓵.𝙘𝙤𝙢

"Alright."

Ruan Liuzheng nodded, without any hesitation.

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

"Teacher, are things not going well?"

Seeing a hint of gloom between Zhao Heng’s brows, Ruan Liuzheng couldn’t help but ask.

She was the kind of girl with keen insight and strong empathy, so she could detect any small changes in others’ emotions.

That’s why anyone who’s interacted with her thinks she has a good temper and personality.

In fact, those she didn’t quite like, she always kept at a distance.

"Things are going well."

Zhao Heng casually said, continuing to sip his coffee.

Yes, coffee is just good with a bit of bitterness. It’s like life, if you think about it, most of it is all kinds of bitterness.

"So, does the teacher find interpersonal relationships too complex?"

Ruan Liuzheng probed.

She had always been able to accurately perceive changes in others’ emotions, and the reasons for those changes were often spot-on guesses. Perhaps this is a particularly unique talent.

"How did you know?"

Zhao Heng was a bit surprised; without saying anything, Ruan Liuzheng seemed to know what he was thinking or worried about. Ruan Liuzheng’s intuition, or empathy ability, was incredibly strong.

By comparison, many people’s hearts are as numb and dull as rotten wood.

"I’ve been aware of these things since I was young."

Ruan Liuzheng smiled and said.

Despite her sweet appearance, her inner strength far exceeds most people.

"Apparently, being a doctor really allows you to use your strengths."

Zhao Heng said, looking at Ruan Liuzheng, with her sweet face.

Everyone has their own strengths, and Zhao Heng’s strength naturally lies in technology. As for interpersonal relationships, it’s just average for him.

The time reached three in the afternoon.

Yanjing University Medical Department.

Medical 3D Reconstruction and 3D Printing Innovation Teaching Center.

At the moment, Zhao Heng and Huang Jincheng were standing in the observation room of the MRI scan room, watching a patient undergoing a deep whole-body scan in a strong magnetic field.

Meanwhile, Ruan Liuzheng and Jiang Rui were naturally standing behind them as assistants.

Gazing at the high-strength magnetic field MRI machine in front, worth over ten million and with a magnetic field strength of 7.0T, Zhao Heng was slightly impressed. Such large equipment was exceedingly costly, and even large hospitals might struggle to afford it.

The MRI is a physical process where atomic nuclei with non-zero magnetic moments spin under the influence of an external magnetic field, causing Zeeman splitting and resonance absorption of radiofrequency radiation at a certain frequency.

The working principle of MRI is through the nuclear spin of hydrogen nuclei within water or fat molecules, causing magnetic moments to appear. The nuclear magnetic moment in a static external magnetic field can drive the nucleus, causing energy level splitting. Along with the effect of the oscillating magnetic field, the spinning nucleus absorbs electromagnetic waves at a specific frequency, where low energy levels can transition to high energy levels, creating signals.

Then, using the linear gradient of the magnetic field to locate and collect signals, the magnet, gradient system, and radiofrequency system connect with the computer system for communication between different electronic components, performing complex interactions. Finally, an MRI image is formed.

Therefore, MRI imaging is a method of examination that uses computers to analyze and diagnose images of human cross-sections. It does not utilize X-rays but rather magnetic fields. Its basic principle is that hydrogen atoms present in the human body resonate when exposed to specific high-wave frequencies under a strong magnetic field, producing a high wave number electromagnetic wave.

This is why MRI is non-damaging to the human body, constituting a non-invasive examination.

"Xiao Zhao, such equipment can be immensely helpful for surgeons."

Huang Jincheng said with some admiration, looking at the clear 3D images that appeared with the deep scan within the operating room.

Modern medicine is actually highly dependent on new technologies.
