Chapter 569
So even if there is indeed a small part of toxic data in so much data, most of the data can be useful in specific databases!
Of course, even a small part of the poison data cannot be allowed to contaminate the entire database.
They have to be caught.
As for the way to find out….
In Lu Yu’s heart, he had already thought about it.
“Doctor Jiang, for our current situation, on the one hand, we need past data to judge.”
“On the other hand, new data is just as important.”
“In the past, the data was more likely to occur because of the different models used. Although the total amount of emerging data is relatively small, but scattered to each data module, their value is very large!
“So we’re going to take the first step next.”
“In fact, it is through some technical means to accelerate data collection!”
Lu Yu said: “And the way I can come up with is to use rapid imaging technology.
“Simply put, it is the use of special methods to speed up data acquisition, such as parallel acquisition, echo chains, windmill technology.”
“All of these technologies can dramatically reduce scan time, improve throughput and patient comfort.”
“For example, SENSE technology uses multiple coils to receive signals simultaneously and restore the complete image through reconstruction algorithms; EPI technology uses multiple echo signals to fill k-space; TURBO technology uses multiple excitation pulses to accelerate data acquisition…”
Dr. Lin cheered up and recorded everything Lu Yu said!
If at the beginning, he still thought that Lu Yu’s words had some credibility, but there would not be many that could really be put into practice.
But now that the topic has reached this level, if Dr. Lin still has the same idea, it proves that he is too stupid.
But how can someone who can do his position be stupid?
Therefore, Dr. Lin also began to take out his notebook for the first time, and wrote down many ideas that Lu Yu was talking about now in his notebook so that he could expand the specific time in the future.
No matter how much the human brain can remember, it is limited.
What’s more, what is currently being said is such an important thing, if any key point is missed, even if only a few words in the key point are missed, it may cause other medical personnel to have a one-sided understanding of the relevant technology, thereby further… Trigger some unimaginable consequences.
So….
For the current situation.
It is the best choice to record all the technical details that Lu Yu will tell next.
“Good.”
Old Doctor Jiang glanced at his student with satisfaction, and a look of praise appeared in his heart.
He had realized this problem earlier than Dr. Lin, but listening to Lu Yu was too serious, and now that he was so old, even if he wanted to record it himself, it was easy to remember something wrong even if he wanted to record it himself.
I was going to let Dr. Lin write those things down later.
But I didn’t expect that Dr. Lin was one step ahead of him, and he started recording on his own before he gave his opinion, and it seems that the master and apprentice all want to go together!
After listening to a lot of Lu Yu’s talk about the technical part….
Doctor Jiang frowned and thought for a moment, then slowly asked
, “What you just said is more inclined to software technology, so if you go according to your plan, are there any requirements for hardware?”
Of course, NMR device technology includes not only the software program in the device, the hardware of the device itself is also very important, even more important than the software in it!
If you really want to implant a neural network in the MRI device to carry out the deep learning of artificial intelligence.
Although Dr. Jiang doesn’t know much about artificial intelligence technology, according to his guess, the hardware level should also use the knife, right?
“That’s right.”
“I just wanted to say this, but I didn’t expect you to take the initiative to mention it.”
Lu Yu nodded gently: “For the current stage of nuclear magnetic resonance equipment, the most important thing is to improve the performance of the probe first.” ”
The probe is an important part of connecting the sample to the machine, and it can receive and send electromagnetic wave signals.”
“Different probes have different characteristics and scope of application, liquid probes, solid probes, multi-core probes, cryogenic probes…. The results are all very different.
“But at this stage, our domestic nuclear magnetic resonance instruments are not deep in the probe, and many probes are mixed.” This… The problem is bigger.
“You also know that choosing the right probe can improve signal sensitivity and resolution. As an example, liquid probes are typically used for the analysis of solution samples, which can eliminate the effects of magnetic field inhomogeneity through spin echoes or gradient echoes…”
“Solid probes are commonly used for the analysis of solid samples, which can improve signal strength and resolution through magic angle rotation or cross-polarization.”
“Well, I understand what you said. In fact, in domestic medical devices in developed cities, these situations are already rare. A hint of helplessness flashed in Dr. Jiang’s eyes:
“But in some second-class and second-B hospitals in less developed cities that do not have so abundant medical funds.”
“There are real cases of this type, and there are quite a few of them.”
“If the probe of the NMR device is classified very carefully, then the capital requirements for the purchase of equipment will be greatly increased, and the improvement effect itself is not so powerful, so some manufacturers have chosen a way to reduce costs.”
“However, if you build a neural network, the hardware requirements in this area are very high.”
“I believe that the hardware can also be lifted!”
“Well, you definitely know more about this than I do, I trust you.”
Lu Yu nodded and continued:
“In addition to the hardware probe problem you just mentioned.”
“Data processing and analysis is also an important part of nuclear magnetic resonance combined with artificial intelligence detection, which can perform some operations on raw data, such as baseline correction, peak fitting, integral calculation, spectrum plotting…”
“Especially next, if we need to implant neural networks in it, the process of data processing and analysis is even more important.”
“Data processing and analysis can improve the readability and accuracy of data.”
“Baseline what? There are also peaks: Peak? “Old Doctor Jiang didn’t hear clearly.
“Baseline correction refers to the removal of baseline drift or noise from the spectrum to make the spectrum smoother and more symmetrical;”
“Peak fitting, that is, using a mathematical model to fit peaks in a spectrum to obtain more accurate peak positions and widths; And the integral calculation value is to calculate the peak area in the spectrum to reflect the relative content of different nuclides…
“Lu Yu patiently explained:
“These are the specific parts involving neural network algorithms combined with data processing and analysis.”
“In fact, you don’t need to understand so completely, and you can leave this aspect to the relevant experts at that time.”
“There is a specialization in the industry, although you are excellent in your field, but in other fields, you have to have their experts to really come forward, and it is possible to create a more complete MRI medical device.”
“Hahaha, I know!” Old Doctor Jiang said with a smile.
“What we said today is too shallow in the end.”
“In this way, when the time comes, we will make a special time to talk to the specific laboratory.”
“If I have any inspiration, I can start working directly, and maybe I can produce results on the same day.”
Lu Yu finally said.
“Makes sense.” Old Doctor Jiang bowed his head slightly, his eyes showed a touch of approval, they had talked enough here today.
Even if we continue to talk, there is only a limit to what we can talk about.
To put it bluntly, the research work is still a practical work in the final analysis, not simply by moving the mouth can be solved, if the solution to the domestic nuclear magnetic resonance device technology can be so simple, just talk about the technology can be solved, will not bother the dragon country until now.
There is limited point in blindly engaging in technical conversations.
“Mr. Lu, today you mentioned so many innovative ideas, we also need to go back and digest them.”
“Thank you so much for your teaching today.”
Dr. Lin on the side also stood up and politely extended a hand to Lu Yu.
“Thank you.” Lu Yu smiled slightly, and then shook his hand, and an inexplicable light flashed in his eyes.
The smoothness of today’s mission was also beyond his expectations. Originally thought…. It would take a while for the hospital system to accept his MRI device technology improvement plan, but the arrival of Dr. Jiang made it all smooth.
It only took a few hours to explain the stakes to Dr. Jiang and Dr. Lin.
Let’s be honest…. It was a real bonus.
“Then, we won’t bother.”
Old Doctor Jiang and Doctor Lin stood up and just wanted to say goodbye to Lu Yu, but their steps were slightly sluggish at the same time.
The two turned their heads and looked at each other, both of them were quite embarrassed in their eyes!
“So, it seems…” ”
We’re the medical examiner here?”
Dr. Lin said awkwardly.
“Ahem, yes.”
“Then Mr. Lu, we won’t bother you, if you feel anything uncomfortable at that time, you can come directly to the physical examination center.”
“The old man will try to help you find out the problem.”
Old Doctor Jiang also used a cough to hide his discomfort.
The two people almost went out just now, but when they turned around, they recalled, this is their physical examination center, where are they looking?
The person who should leave is obviously Lu Yu!
This was listening too seriously, so that both people subconsciously thought that Lu Yu was the master here, and they were the students who came to listen to Lu Yu’s class….
But in a sense, the reality is still true! After all, although they also put forward their own understandings and conjectures throughout the “defense” process.
But most of the time….
It’s all spoken in Lu, and they listen.
To say that in this technology, Lu Yu is their teacher, there is really nothing wrong with this statement.
“Okay, then I won’t bother the two of you to continue to receive the doctor.”
Lu Yu immediately saw why the expressions of Dr. Lin and Dr. Jiang became so embarrassed at the same time, but he did not say it directly, but endured a smile and left the physical examination center all the way.
“Gone.”
He waved the researcher’s hand, signaling for the two of them to leave.
“Okay, Mr. Lu… Mr. Lu. The
researchers from the Zhurong-2 Aerospace Research Center were also stunned for a second, then stood up and planned to leave.
Looking at Lu Yu’s back when he slowly stepped onto the car, his eyes showed a hint of apprehension:
“This… If I go back and explain to Director Lin like this, it should be fine, right? The
reason why Director Lin brought him over with Lu Yu today was also because he was worried that Lu Yu would “serve yang and yin”, although he agreed to the request for a physical examination on the surface, but in fact, he went out to secretly continue the command and arrangement of the microsatellite network.
In order to allow Lu Yu to undergo the physical examination with peace of mind, Director Lin is also well-intentioned.
But who would have thought that things would go in such a strange direction?
Obviously, Lu Yu came over today, he came for a physical examination!
But…. In the end, it has become to take the domestic NMR device technology to a higher level, from the identity of a patient to a teacher!
Not to mention Director Lin, who was far away in the research center, even he who followed Lu Yu did not dare to think about the development of things in this direction an hour ago!
“Ahem.”
“Anyway, at least it’s a good thing.”
“Even if Director Lin really wants to blame me, he shouldn’t punish me, and scold me at most twice… Well, yes, definitely.
After comforting himself in his heart, the researcher did not stay in this physical examination center for a long time, but left the physical examination center all the way with Lu Yu’s steps.
“Let’s go!”
Lu Yu smiled.
At least on the way to the physical examination, Lu Yu never dared to imagine that today’s physical examination task could be so smooth!
Just the next task… It’s going to have to get more!
No way, the greater the ability, the greater the responsibility.
Lu Yu secretly recalled this sentence in his heart, and after traveling into this world, he had become more and more fully aware of the meaning of this sentence.
—
Kyoto, in a hotel
, “In the past two days, why have your legs not improved, but have become more and more sore?”
“It seems that our kind of hospital in Luohai City still has no way to compare with the big hospitals in Kyoto.”
A middle-aged man rubbed his thighs and sighed continuously.
“Old Willow, I said you don’t need to be suspicious, you should be too busy with work, running around every day, running legs sore!”
“There shouldn’t be any problems.”
A lady next to her slowly comforted.
