Movie black technology

During this period of time, Zhouzhuang conducted several tests and added several new subjects. The results all proved that photoacoustic detection is harmless to humans.

This also confirms the evaluation of this technology in the system.

In fact, thinking about it, this thing does not carry radiation, nor does it damage the body structure, but only makes the body slightly hot.

The impact of a fever on the body is more serious than a photoacoustic test.

Now the mice in the experimental area are performing laser scanning uninterrupted every day, and no abnormality can be found until now.

Therefore, the security of this technology has been initially adopted in principle and practice.

In terms of accuracy, through the blood glucose analysis algorithm, it can also be determined that the accuracy of the photoacoustic detection is no problem. Its accuracy is much higher than that of a blood glucose meter. The current results are basically consistent with the blood test.

"Is that fast? Is there any problem with the instrument?" Father Chen asked.

Chen Shen leaned on the wall and said, "Now we can conduct a preliminary large-scale experiment, so that we can not only test the test results of the machine, but also observe the society's reaction to it."

As he said, he checked the date, "The internal imaging program on the smart center should be almost developed. With this program, the large-scale experiment of photoacoustic detection will be much smoother."

Although the current smart center is still expanding its enrollment, it has already squeezed enough manpower to solve the most urgent internal imaging algorithms and procedures.

This program can reconstruct the image of the human body, just like ultrasound imaging, except that the clarity is much better than ultrasound imaging.

With this program, it is possible for him to start the external test of photoacoustic detection.

Otherwise, the photoacoustic scanner is equivalent to an oversized blood glucose monitor, and no one would agree to spend a lot of money to build a blood glucose monitor.

Father Chen continued to ask: "Then how much money do you expect for this experiment?"

Chen Shen had already estimated this problem.

He immediately said: "The cost should be between one billion and one billion."

"Hey! The price is too high!" Father Chen couldn't help being surprised, knowing that this was just an experiment.

"The cost here is mainly divided into two parts." Chen Shen explained patiently.

"One part is the cost of the instrument itself. The cost of a complete set of photoacoustic scanners is at least 40 million yuan. This cost cannot be saved."

Although the photoacoustic scanner is very small compared to other medical instruments, if all the main components such as the main unit, laser scanner, and photoacoustic sensor are removed, they can be placed on a table, but The various fine parts and components used in it are not cheap at all, they all need to be set up separately and produced using new technologies.

This cost is unavoidable.

Chen Shen continued: "In addition, the signal collected by the photoacoustic scanner requires a lot of calculations to analyze, so we need to equip it with a sufficiently powerful supercomputer center."

Although he used the computer in the base to calculate the blood glucose level information in the signal before, it was only the most basic and simple algorithm program.

If you want to obtain other information, you need to perform tens of millions or even billions of times on the signal, and such calculations must be completed ten times in two seconds.

At the same time, there are still thousands of people's data that need to be calculated, and the computing resources required for this are very scary.

In addition, after the results are calculated, the results need to be output and feedback to the inspectors through the network, so an additional server center is needed.

"Supercomputing Center?"

When Father Chen heard what Chen Shen said, he was even more surprised.

He almost thought he had heard it wrong.

"Yes," Chen Shen nodded and said, "According to my expectation, after the photoacoustic signal analysis algorithm is fully mature and can be tested in various aspects, to achieve the calculation effect I envisioned, you probably need a Shenwei Blu-ray. Level of super calculation."

"Your dad, I don't know super calculations, so you can elaborate more."

"It's probably an overcalculation with a continuous computing capacity of 750 trillion times per second, and the cost is about 600 million."

This cost is inferred from the construction cost of the Nanji Supercomputing Center. As a supercomputing center started 10 years ago, its total investment at that time was 600 million.

At this time, hardware costs should be reduced, but considering other costs, the overall situation will not change much.

Chen Shen went on to say: "According to my calculations, such a supercomputer can calculate and analyze the photoacoustic signals of 1,000 people at the same time. That is to say, once you have this supercomputing center, in the most ideal state, every minute The scanner can detect 30,000 people."

"In addition, the cost of the supercomputing center plus the cost of the server, and other fragmentary expenses, the cost of the entire experiment is at most one billion."

Listening to his son's words, Father Chen couldn't help being a little silent.

He calculated that the smart center has been expanding wildly recently, and the brain-computer center is also consuming a lot of funds...

Money seems to be getting insufficient!

Chen Shen also knew what he was thinking, and smiled and said: "What I just said is only the highest standard experimental plan, and it doesn't have to be the above method."

Comrade Chen patted his chest: "Then you should talk about other cheaper solutions!"

"In the initial testing phase, we only need to build the scanning center and arrange the photoacoustic scanner. The server platform only needs simple construction. The most important computing resource can also be used with the company's current computing platform. But the calculation speed will not be too fast."

"If we follow this plan, the cost will be around 100 million yuan."

Hearing this, Old Chen breathed a sigh of relief: "This is acceptable."

If it's only 100 million, the company can still get it.

He asked again: "But someday there will be supercomputers. It is impossible for us to build this, right?"

"No, our project is a cooperative project. The Supercomputing Center should be in charge of Dasheng Industrial."

"That's good, I see no one has contacted people for specific details during this period, so I am a little worried."

"Someone will contact you in a while," Chen Shen said.

In fact, even if they want to build a supporting supercomputing center, they don't have that chance.

It is important to know that once the photoacoustic scanner is put into practical use, a large number of real-time physical information of the people will be received every day. It is self-evident how important these data are. As a private company, it is impossible to control these data.

So they honestly do a good job of providing technology and make money with their thighs.
