During this time, Zhou Zhuang conducted several more tests and added several new experimental subjects, and the results 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 carry radiation, and it will not destroy the body structure, but it just makes the body heat up a little.

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

Now the mice in the experimental area are constantly laser scanning every day, and they can't find any abnormalities so far.

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

In terms of accuracy, through the blood glucose analysis algorithm, it can also be determined that there is no problem with the accuracy of photoacoustic detection, and its accuracy is much higher than that of blood glucose meters, and the current results are basically consistent with blood tests.

"So fast? Is there no problem with the instrument anymore? Father Chen asked.

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

As he spoke, he looked at the date, "The internal imaging program on the side of the intelligent center should have been almost developed, and with this program, the large-scale experiment of photoacoustic detection will be much smoother." ”

Although the current intelligent center is still expanding, it has squeezed out enough manpower to give priority to solving the most urgent internal imaging algorithms and programs.

This procedure can reconstruct images of a person's body, just like ultrasound imaging, but with much greater clarity than ultrasound imaging.

With this procedure, it was possible for him to initiate external tests for photoacoustic detection.

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

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

For this problem, Chen Shen has already estimated.

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

"Shhh The price is a bit too high! Father Chen couldn't help but be surprised, knowing that this was just an experiment.

"There are two main parts to the cost." Chen Shen patiently explained.

"One part is the cost of the instrument itself, the cost of a complete set of photoacoustic scanners is at least 40 million, and this cost cannot be saved."

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

This cost cannot be avoided.

Chen Shen continued: "In addition, the signals collected by the photoacoustic scanner need to be analyzed by a lot of calculations, so we also need to equip it with a powerful enough supercomputing center. ”

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

If you want to get other information, you need to perform tens of millions or even billions of times more complex calculations on the signal, and this operation needs to be done ten times in two seconds.

At the same time, there are thousands of people's data that needs to be calculated, and the computing resources required are terrifying.

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

"Supercomputing center?"

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

He almost thought he had misheard.

"That's right," Chen Shen nodded and said, "According to my prediction, after the photoacoustic signal analysis algorithm is fully mature and can be detected in many aspects, if you want to achieve the computing effect I envisioned, you will probably need a supercomputer at the level of Shenwei Blu-ray." ”

"Your dad and I don't know how to do supermath, you can be more detailed."

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

This cost is estimated based on the construction cost of the Nanji Supercomputer Center, which was built 10 years ago, and its total investment at that time was 600 million.

By this time, the cost of hardware should be lower, but considering other costs, it won't change much overall.

Chen Shen continued: "According to my calculations, such a supercomputer can calculate and analyze the photoacoustic signals of 1,000 people at the same time, which means that once you have this supercomputing center, in the most ideal state, the photoacoustic scanner can complete the detection of 30,000 people per minute." ”

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

Listening to his son's words, Chen's father couldn't help but be a little silent.

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

Money seems to be getting shorter and shorter!

Chen Shen also knew his thoughts, smiled and said, "What I just said is only the highest standard experimental plan, and it doesn't necessarily have to be the above method." ”

Comrade Lao Chen patted his chest: "Then let's talk about other cheaper solutions!" ”

"In the initial testing stage, we only need to build a scanning center, arrange a photoacoustic scanner, and the server platform only needs to be built simply, and the most important computing resources can also be used on the company's current computing platform, but the computing speed will not be too fast."

"If you follow this plan, the cost will be about 100 million."

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

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

He asked again: "But one day we will use supercomputing, and we can't build this, right?" ”

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

"That's good, I don't see that anyone has contacted anyone for specific details during this time, so I'm 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 opportunity.

Once the photoacoustic scanner is put into use, a large amount of real-time body information will be received from the people every day, and it is self-evident how important these data are, and it is impossible for a private company to control this data.

So they honestly do a good job as a technology provider, just hold their thighs and make money.
