Chapter 208 Preparing for the Practical Experiment of Photoacoustic Detection (44)

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

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

In fact, if you think about it, you know that this thing does not contain radiation, and it will not damage the body structure, it just makes the body slightly warm.

A fever has a more serious impact on the body than a photoacoustic test.

Now the mice in the experimental area are scanning lasers non-stop every day, and no abnormalities have been found so far.

Therefore, the security of this technology has been preliminarily passed in both principle and practice.

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

"Is it so fast? Is there no problem with the instrument?" Father Chen asked.

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

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

Although the current intelligence center is still expanding its enrollment, it has squeezed out enough manpower to give priority to solving the internal imaging algorithms and programs that he needs most urgently.

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

With this program, it was possible for him to start an external experiment with photoacoustic detection.

Otherwise, the photoacoustic scanner is equivalent to an oversized blood glucose monitor, and no one will 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 to need for this experiment?"

For this problem, Chen Shen had already estimated it.

He immediately said: "The cost should be between 100 million and 1 billion."

"Hiss! This price is a bit too high!" Father Chen couldn't help being surprised, you know this is 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. A complete set of photoacoustic scanners costs at least 40 million yuan. This cost cannot be saved."

Although the photoacoustic scanner is very small compared to other medical instruments, if the main components such as the host, laser scanner, and photoacoustic sensor are all disassembled, they can be placed on a table, but The various fine parts used in it are not cheap at all, and all of them need to set up another production line and use new technology to produce them.

This cost cannot be avoided.

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

Although he used the computer in the base to calculate the blood sugar level information in the signal, it was just the most basic and simplest algorithm program.

If you want to obtain other information, you need to perform calculations that are tens of millions or even hundreds of millions of times more complicated on the signal, and such calculations must be completed ten times within two seconds.

At the same time, there are still thousands of personal data that need to be calculated, and the computing power resources required are terrifying.

In addition, after calculating the result, it is necessary to output the result and give feedback to the inspector through the network, so an additional server center is needed.

"Supercomputing Center?"

Father Chen was even more surprised when he heard God Chen's words.

He almost thought he had heard wrong.

"That's right," Chen Shen nodded and said, "According to my estimation, after the photoacoustic signal analysis algorithm is fully mature and can perform multi-faceted detection, if I want to achieve the calculation effect I imagined, I will probably need a Sunway Blu-ray A level of overcomputing."

"Your dad, I don't know supercalculation, so please explain in more detail."

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

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

By this time, the hardware cost should be lower, but considering other costs, there will not be much change overall.

Chen Shen went on to say: "According to my calculations, such a supercomputer can simultaneously calculate and analyze the photoacoustic signals of a thousand people, that is to say, once you have this supercomputing center, in the most ideal state, the photoacoustic signals can be processed every minute." The scanner can complete the detection of 30,000 people."

"In addition, the cost of the supercomputing center plus the cost of the server, and other small 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 figured it out, the intelligence center will expand wildly recently, and the brain-computer center is also consuming a lot of funds...

Money seems to be getting worse and worse!

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 necessarily have to follow the above method."

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

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

"If this plan is followed, the cost will be around 100 million."

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 there will be a day when supercomputers will be used. It is impossible for us to build this?"

"No, our project is a cooperative project, and the supercomputing center should be in charge of Dasheng Industry."

"That's good. I don't think anyone has contacted anyone with specific details during this period of time. I'm a little worried."

"Someone will contact you after a while." Chen Shen said.

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

We must know that once the photoacoustic scanner is put into practical use, a large number of real-time physical information of citizens 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 as a technology provider, and just hold their thighs to make money.
