Chapter 1184： Chief complaint (1/2)
”Director Huo, check it up, just take an MRI, what are you nervous about?” The nurse on duty was spontaneous, and at his young age, he was also very careful when speaking to the director.
At the age of Huo Congjun, seeing the little girl in her early 20s naturally made her smile, and only hung a bit of bitterness in the corner of her mouth, deliberately complaining: ”Where do I need to do MRI. The MRI is required, it should be Ling Ran Right.”
”Dr. Ling also cares about you.” The director guessed that the little girl didn't have to hide it.
Huo Congjun hummed and said, ”You young people, know what cares about people. You are not experienced until my age...”
He was expressing emotion, and saw the little girl in front of her with a mouthful of laughter, and frowned and asked curiously: ”Which part of the story do I have a joke?”
”You young people.”
”This kind of title can't be used now?” Huo Congjun was surprised.
”What kind of title is this?”
”It's like a little princess.”
”Where do you want to go?” The little girl acted passively, and then said: ”I laugh because you said ”you young people”, including me and Dr. Ling.”
Huo Congjun said: ”How long has it been, even if Ran Ran is handsome, he is handsome enough.”
”No, still as handsome as before.” The little nurse held her hands in both hands.
Huo Congjun chuckled and took the initiative to lie on the MRI metal sheet bed.
The little nurse did another check before pushing the door out.
Soon, the rumbling noise of the rumble of the nuclear magnetic resonance rang.
Speaking of which, MRI is really high-tech, and it can even be called black technology. Its principle is to use atomic nuclei to resonate in the magnetic field, thereby reconstructing the imaging.
It sounds like a problem that can be solved with a strong magnetic field, but actually contains at least two Nobel Prizes.
The first Nobel Prize came out in 1944. It rewarded the discovery of the 1930s: the nuclei in the magnetic field would be arranged in an orderly parallel direction in the forward or reverse direction of the magnetic field, and after the application of radio waves, the spin direction of the nuclei reversed .
The second Nobel Prize came from 1952 and was used to reward the discovery of 1946: placing an nucleus with an odd number of nuclei in a magnetic field and then applying a radio frequency field at a specific frequency will cause the nucleus to absorb radio frequency field energy.
After this, a round of basic scientific research investment is needed to slowly establish the foundation of the MRI machine.
In 1974, Robo Loher and his team took the famous MRI picture ”Nottingham's Oranges”, not to mention how much it cost to build a 0.15T MRI machine by hand in the past, just ten A team of several people, for more than ten years, is an amazing project cost.
Before patients can do MRI in the hospital, more professional terms are needed. Such as Fourier transform, such as superconductivity, such as surface coils and active shielding...
It can be said that nuclear magnetic resonance is an instrument that truly reflects the development of modern science and technology, and it is a great application to modern science, especially basic science.
If someone asks, what is the investment in science projects, especially basic science that seems useless? If you take nuclear magnetic resonance as an example, then you can answer politely: don't hide it, it can be used to save your mother.
Of course, most people do not believe that they need to be saved.
Just like Huo Congjun, after finishing the MRI, he was still unhappy and said: ”I am really okay. Forget it. Doing an inspection will also give you peace of mind.”
”It's alright to be the best.” The little nurse pretended to be cute and quickly led the director out. There are more patients waiting to see a doctor later, especially after Ling Ran’s return, the MRI machine of the whole hospital can’t wait to work for 25 hours a day.
”Ling Ran?” Huo Congjun went out and asked with a clear cough.
”Doctor Ling is in the office.” The little nurse smiled.
