It's not that hard to open a hospital in another world, right?

Chapter 1376 Lord of Thunder, can you know Fourier transform?
The Thunder Lord glared at Gretel.

Gretel looked up at the Thunder Lord.

Wink, wink, wink.

"Teacher~~~Look at this heart valve, you really can't see clearly~~~"

The sugar content in the sound is definitely to poke over the honeycomb, and then double the sugar in the honey.The Lord of Thunder couldn't help but want to frown. If he was in another place, he would have already opened his mouth to scold him:

Such an adult, still acting like a baby?You are already a fourteenth-level high-level mage, not those fourth-level little guys who are just out of school and running around everywhere!

Uh, the little guy at the fourth level, it seems that he hasn't come to his door yet...

But looking around, he swallowed the scolding again.Gretel looked at him eagerly, and the silver dragon girl looked at him eagerly;
Forget it, all the elves standing on the ground respectfully and respectfully looked at Gretel.

Although unlike Nevis, mages mostly wear level badges, but the aura, at first glance, is the powerhouse of level [-], [-], [-], [-], and even a half-step legend.

In front of these people, I still have to save some face for my disciples.

Two hours.

Gretel paced up and down, up and down.

The Lord of Thunder remained expressionless, experimenting silently.The icy breath from rubbing hands has indeed greatly enhanced the strength of the magnetic field.This little guy, the direction mentioned in a casual sentence, is actually really useful!

The commercial version commonly used in tertiary hospitals, 3.0T MRI, can also achieve a resolution of 1 mm, that is to say, tissues as small as 1 mm can be seen clearly;

"Teacher... lower the temperature..."

"Teacher, look, I can't see clearly like this! I can barely see the outline, whether there is incomplete opening and closing, what shape it is, and whether there is any growth on it, I can't see clearly at all!"

Ok?
The Thunder Lord cast a sidelong glance at him.Lowering the temperature can increase the power of lightning, which he has long known.Starting from this point, it is possible to increase the strength of the magnetic field, he also thought about it;

Then, layers upon layers around him, a huge tornado was sucked in by him like a funnel.The cloud surged, almost covering his figure. Gretel subconsciously wanted to follow, but was grabbed by Cerilla:
The silver dragon girl stared at the Thunder Lord's figure hidden in the clouds and mist, her small face was tense, and her whole body trembled slightly.

1 minutes.

Three 10 minutes.

The oscillation of each magnetic field also has a time dimension.The magnetic field is enhanced, and the oscillation frequency can also be increased. To find the signal he needs from the messy feedback, and finally to image, means to process more information...

Although he really doesn't know whether liquid nitrogen or liquid helium can be used for Void rubbing, but cooling down, cooling down, down to an extremely low temperature seems to be a way of thinking?

Set up a force field wall, condense a cold liquid from the air, and dance lightning in the liquid.The consumption is only doubled, but the magnetic field has increased by more than ten times!
However, the increase in the strength of the magnetic field does not mean that you can easily see things more clearly.The Lord of Thunder simulated it a little bit, and he felt a headache:
The improvement in accuracy means not only an increase in energy, but also a significant increase in the required computing power.

If it wasn't for Gretel's suggestion, try it with an orange first, he couldn't tell the difference between the peel, the petal, and the core;
Then, in order to see the mouse's head clearly, he increased the output power of the magnetic field by ten times, and only got a blurry image, where the eyes, the skull, and the brain could not be seen clearly;

The face of the Lord of Thunder became serious little by little.Gretel's request cannot be said to be unreasonable, and it can even be said that in order to achieve a good enough treatment effect, it must be seen so clearly;

But the problem is that this path, in his plan, is ranked fifth...sixth...eighth to try!This kid, why is his mouth so fast!

A very simple reason.From a cube with a side length of 3 mm, 27 cubes with a side length of 1 mm can be cut out;

But now, he can finally see the pig's heart clearly, and even show the beating of the pig's heart. Little Gretel actually wants to see the valves in the pig's heart clearly!
That thing about the valve... that thing... The Lord of Thunder tried hard to recall the information that Gretel handed him:

15 minutes.

But it's the same shape.The inside of the clam shell is messy and black, and the internal structure is basically invisible.

Gretel probed his head.

"Need to see so clearly?"

Even if this is impossible, at least give me a 1.5T NMR!

I'm afraid I'm going to be beaten into a meatloaf!

The power rising from the cloud was condensed, fierce and cold.Compared with her breath, compared with the breath of the elders in the family, it is much colder and more terrifying!
This is... a legend...

Gretel opened the record book, flicked his fingers, and a mysterious eye passed over the pig's ear, and the number on the ear tag was clearly displayed.Gretel flipped through the record book following the numbers on the ear tags:

"Continue to improve!" Gretel nodded firmly.The nuclear magnetic resonance of later generations, before he crossed, there were already 7T machines, and the resolution could reach 0.5mm;

Gretel yawned, but didn't dare to go to sleep again.Teacher, how long have you been doing this round of NMR...

5 minutes.

The Lord of Thunder stood by the lake for a long time, and suddenly waved.A clam the size of a palm flew out from the bottom of the water and fell into his demiplane.

What clam feet, what adductor muscles, what aorta, what intestines...

Generally speaking, a scan takes 15 minutes to half an hour, and the emergency department can get the report in half an hour at the earliest... It takes two hours!It's been two hours!

2 minutes.

I can only make difficult guesses in the dark black and light black mess, which is a test of people's spatial imagination.

Then, the Lord of Thunder lowered his eyes silently, and stood like a statue by the lake.

Well, the main reason is that liquid helium is more expensive, and the magnet is immersed in it; liquid nitrogen is cheaper, and it is kept warm outside~~~
In the unlikely event that a hospital should be unlucky and someone/has a wheelchair/something the hell gets sucked into the machine and has to be degaussed to get it off, those liquid nitrogen and liquid helium out, that's a big job!

Forget it, let's think of it as working overtime in the emergency department, or the patient's family members waiting for news outside the clinic.The closest family members, who can sleep at this time?
After waiting for another two hours, the Thunder Lord finally let out a sigh of relief and waved to Gretel.

While speaking, he held a liquid nitrogen test tube under his fingertips and shook it at the teacher.He doesn't know anything else, but the nuclear magnetic resonance machine in the previous life used liquid nitrogen and liquid helium to cool down to achieve the superconducting effect.

"Let me think about it." He whispered softly, "Let me think about it..."

"Teacher, the radius of the pig's heart valve ring is about 10 millimeters. If you want to see clearly, your accuracy here should be increased to at least 1 millimeters, not to mention 2 millimeter!"

One hour.

"No. 51... No. [-] is infundibulum and pulmonary valve stenosis, combined with pulmonary valve and right ventricular outflow tract vegetation... You see, if you can't see this clearly, you will have big problems if you do surgery!"

Then put a row of mosaics on it, each mosaic grid is as big as two centimeters by two centimeters...

To increase the accuracy from 3mm to 1mm, the computing power required is not 27 times.

Has the teacher finished the scan and is calculating the results, or has the scan not yet been completed?Just such a small river clam...

"So the accuracy will continue to improve?"

In order to perform surgery, do you need to see this thing clearly?

"Of course we need it!" Gretel puffed out his chest confidently.As soon as he stretched out his hand, an elf sprinted into the laboratory, and then sprinted out, holding a record book in both hands;

Gretel trotted over, and sure enough, a silent phantom hung in front of the Lord of Thunder, and its shape was exactly the same as the clam shell next to it.

The valve seems to be a piece of the heart?Sometimes it is opened, sometimes it is closed. When it is opened, blood can pass through it, but when it is closed, blood cannot pass through it?

While talking and making gestures.First use light and shadow to outline a radius of 10 cm, divided into three roughly equal fan-shaped things that open and close continuously;

Well, it's definitely not because it's on the territory of elves, it's not easy to beat children!

After thinking about it, the Lord of Thunder finally decided to return to the topic, and asked in a deep voice.

When he first participated in this project, all he could "see" was a piece of shit that couldn't be explained in words——

Indeed, for a healer, the clearer he can see, the better, but for an exporter like him, the more clearly he can see, the more tired he is!

Can he go back to sleep and come back tomorrow morning to wait for the results?He is not a legend yet, he still needs a certain amount of sleep and meditation to maintain his mental state and spell position!
Gretel didn't dare to go back to sleep with such slander in his heart.The teacher was busy with his affairs, so he went back to sleep leisurely, and woke up tomorrow morning...

The problem is that with his current probing accuracy, the side length of the grid he punched out even exceeds 5 millimeters.It needs to shrink to a size of 2 millimeters, and the energy he needs to spend in one cast is more than 10 times!

However, since the little guy said it, it's all right for the Lord of Thunder to put it first in the queue to try.He took a few steps outside, his figure suddenly disappeared from the spot, and the next moment, he appeared by the lake several hundred meters away;

Teacher, you are a legend, you cannot be inferior to a 1.5T NMR!

He lowered his eyes, contemplating.Beside him, Grete turned his left foot to his right foot, and his right foot to his left foot. After waiting nervously for a while, he whispered:

Gretel sighed helplessly.

It was his fault, it was his fault.The signal obtained by nuclear magnetic resonance needs to be transformed by Fourier to make a detailed image that can be understood by doctors at a glance.

So now comes the question -

Teacher, you are a legendary mage, do you understand Fourier transform?
I have learned this stuff, tested it, and immediately forgot it. If you don’t understand it, I really don’t have the confidence to explain it to you...
