Su Yunbai was very dissatisfied with her performance.

Huo Qinian was a man who was very good at seizing opportunities. To put it bluntly, he could even be called scheming. She knew his character very well, but she was still not vigilant enough.

After the kiss on the center of her eyebrows, she could even see the joy and excitement in Huo Qinian's eyes - he was such a smart man, he must have been encouraged by her reaction.

This also meant that what was going to greet her next would be an even more intense "crazy bombing" of Huo Qinian's style.

Whenever Su Yunbai thought of this, she felt a headache.

She decided not to give him a good face during the entire winter vacation - he was the kind of person who would take advantage of others and she really couldn't get used to it.

But Su Yunbai's plan was not implemented in time. Even Huo Qinian himself did not "strike while the iron was hot". Their attention was drawn to another thing -

shortly after Christmas, a respiratory infectious disease began to spread in the country...

Later, when Su Yunbai recalled her experience during this period, she always felt that she was living in a magical realist world - the world became something she could not understand at all.

To a certain extent, her perception of the entire world was reshaped because of this.

From the perspective of the moment, no one knows how things will end. This feeling of confusion and hopelessness makes people panic.

At this stage, there were no related cases in the United States, so the two of them paid attention to the news in the country at the same time, but maintained a strange tacit understanding, and neither of them talked about it in front of the other.

Su Yunbai could feel that Huo Qinian was getting more and more anxious day by day. This was already very unusual for him.

He often frowned as if thinking about something, and looked at Su Yunbai, hesitant to speak.

Su Yunbai had some guesses in her heart.

One day in mid-February, Su Yunbai's guess was verified -

she had just returned from school that day and saw Huo Qinian standing quietly at the door of his house.

He did not come alone. Beside him, there were several familiar faces to Su Yunbai - Huo Qinian's two assistants, a vice president of Huo's, and three group executives.

They surrounded Huo Qinian and followed him to stand in the snow in February. The man who was surrounded was frowning and thinking about something, and even the sound of Su Yunbai's car engine could not interrupt his thoughts.

Su Yunbai got out of the car and closed the door.

The heavy sound of the door closing finally attracted Huo Qinian's attention. He looked over, pursed his lips, and frowned slightly. His expression was so depressed that Su Yunbai couldn't even understand his emotions at first.

Huo Qinian looked at Su Yunbai, and his Adam's apple moved obviously, as if he had a lot of words to say. But in the end, he just took a deep breath, as if to suppress his emotions as much as possible.

He said, "Yunbai, I need your help."

Two hours later, several people sat in Su Yunbai's study, each with a computer.

At the same time, twenty-two people came into the online conference room exclusive to the Huo Group, plus the six people on their side, a total of twenty-eight people.

In the split-screen window displayed on the computer screen, most people sat upright with serious expressions.

Huo Qinian spoke first, his voice was very steady: "Hello everyone, I am Huo Qinian. I believe everyone knows the purpose of this meeting - we are developing and improving our intelligent medical system, hoping to make our own contribution to the diagnosis and treatment of respiratory diseases this time.

"The world is difficult, but I believe this is all temporary hardship. During this time, I hope we can work together and support each other...

"The group will not forget your efforts...

"The technical consultant we invited is Associate Professor Su Yunbai Su, an associate professor of medical physics in the Department of Physics at R University. Associate Professor Su’s topics include image post-processing, image noise reduction, and AI automatic target area delineation...

"Before this, she was also the developer of TargetR, a product invested by our group. I believe most of the people here are familiar with her.

"Before Associate Professor Su began to explain her scientific research results, everyone introduced themselves first. "

Microphones lit up one after another in the small window on the computer screen.

"Hello, everyone. I am Zhang Zhiheng, Deputy Director of the Technology Department of Huo's..."

"Xu Fangjie, Director of the Marketing Department..."

"...Zheng..., Head of the Intelligent Medical Group of Maosheng Medical under Huo's..." "

...Gong Shaowen, Director

of the Research and Development Department of Huo's Leading Technology..." In general, among the 28 people attending the meeting, except for those leaders who can directly decide on the Huo's major strategies and those who are related to market research, most of them are the backbones of research and development under the major topic of Huo's intelligent medical care.

Huo Qinian made a "please" gesture to the camera and said, "Minister Xu, please tell us first, in the market...or at this stage, what kind of technology and what kind of medical functions are the most scarce and most needed."

"Okay. At this stage, what we want to do most is to help medical staff quickly confirm the patient's condition and complete the triage of light and severe cases.

"At present, the diagnosis of the disease mainly depends on various symptoms, but this is actually not accurate enough. After the symptoms appear, you still have to take a chest X-ray and confirm the diagnosis through CT scans.

"Nowadays, medical resources are in short supply. We hope that smart medical care can help medical staff read films and confirm symptoms, thereby relieving the pressure on medical staff.

"In addition, we also hope to help develop a rapid detection method to confirm whether a patient is infected. Of course, this is the second plan..."

After Minister Xu finished speaking, Huo Qinian wanted to look up at Su Yunbai, but he held back.

He still faced the camera and said calmly: "Professor Su, if I remember correctly, CT scan diagnosis of cases... is this one of your topics?"

Su Yunbai nodded.

"Yes. Everyone should be short on time, so I skipped the greetings and got straight to the point.

"For the function of intelligent medical reading of images and helping to confirm the condition, I think three major technologies can be combined..."

Su Yunbai shared his screen and opened the PPT.

"The first one is AI automatic target area delineation technology, which is actually a type of image recognition technology. The reason I mentioned this is because this technology has been used in TargetR...

"The so-called automatic target area delineation technology, in layman's terms, means that when you provide a CT scan, AI will read the information in the scan, determine where the tumor is, and delineate the area of ​​the tumor with an accuracy of...

"The same principle can be applied to the chest CT scan of the patient this time. We all know that patients' lungs will show varying degrees of fibrosis, which is one of the important bases for diagnosis.

"Fibrosis can be seen on CT scans. What we have to do is to shift the target of 'delineation' from cancer to fibrosis. In other words, AI previously diagnosed cancer, but now it determines fibrosis.

"The accuracy of the delineation will be directly linked to the degree of fibrosis. To some extent, this is one of the bases for distinguishing between mild and severe illnesses.

"This involves comparing various numerical values ​​of CT technology, CT images and human tissues. After all, the imaging of cancer and fibrosis on CT is definitely different...but the basis of automatic outlining technology is there, and this part of the technology should not be difficult.

"In addition, standards for severity and degree of fibrosis should also be established.

"We all know that AI processes digital information, even images, in the final analysis are digital information. We humans can judge which degree is mild and which degree is severe based on our feelings. But AI is different. AI must have a digital standard. If it exceeds this number, it is one degree, and if it does not reach this number, it is another degree.

"We must establish this digital standard in advance, which can be guided by experts..."

Huo Qinian's "forced approach" to Su Yunbai over the past year or so was not in vain.

At least now, he can understand most of what Su Yunbai said.

Huo Qinian looked at Su Yunbai in front of the camera through the screen.

Her serious look was really attractive.

The camera was facing Huo Qinian, and this meeting was also recorded in real time. ... Huo Qinian knew that as President Huo, he really shouldn't show any distraction at this time.

But he still couldn't help but raise his head and look at Su Yunbai.

She was sitting not far from him, wearing headphones, talking seriously in front of the computer screen.

Huo Qinian looked at her, thinking of what he was going to do after today, and his mind wandered uncontrollably.

Su Yunbai continued: "The second technology is image noise reduction technology. Taking CT scans involves the issue of radiation dose, which is actually a bit similar to the exposure in film photography...

"It's a very simple truth. If you give too little radiation dose, the image that comes out will definitely not be clear, just like the film is not well exposed. "

Of course, this doesn't mean that the more dose you give, the better. There is a reason why people are afraid of radiation. A healthy person should not be exposed to large doses of radiation...

"Image noise reduction technology, in short, means that I can get a clear image with a smaller dose..."

Su Yunbai turned the page of the PPT, "Next is the third technology, image sharpening technology..."

In half an hour, Su Yunbai quickly finished her PPT, "These are the three technologies I want to share today. Do you have any questions?"

While waiting for questions, she took the opportunity to drink some water.

Before she put down the cup of water, a noisy sound came from the earphones - she was almost drowned by questions.

"Hello, Professor Su. I agree with what you said about AI automatic outlining being able to help with diagnosis. But what I don't understand is why image noise reduction is also used here?

" "I can understand that good image quality can help medical staff and AI diagnose the disease. But things have their priorities. Integrating one more technology means that more time will be needed, and what we lack most now is time.

"I suggest taking an appropriate amount of dose when taking the CT scan to obtain a CT film of appropriate quality, and then directly diagnose. After all, we all know that in terms of medical radiation doses, it is actually far from causing irreversible harm to the human body..."

"I suggest that this part of the image noise reduction technology be regarded as a supplement to the second update. What do you think? "

Everyone present here is a backbone of R&D. Although they may not have any ill will towards Su Yunbai, they all have their own pride.

If Su Yunbai cannot convince them, or is stumped, then her role as a technical consultant will be a bit ugly.

Of course, Su Yunbai is not afraid of this at all.

She picked these three out of her own topics, and naturally she had thought it over carefully.

Su Yunbai put down the water glass and said, "I understand what you mean, and this is indeed an idea. But I still suggest integrating this technology, mainly for two reasons.

"First, no matter what, the less radiation, the better. Especially when the patient is ill and may still be suffering from various complications, I think any approach that can reduce the burden on the body is not in vain. "

Of course, this is only one consideration. Most importantly, for AI, this technology can help them make more accurate judgments.

"We know that image denoising is actually a process of machine learning. In this process, adjusting parameters can actually change the sharpness of the image...

" "As I said before, if we look at it from the perspective of human eyes, changes in sharpness may result in the loss of some information. This hinders our naked eye's ability to distinguish.

"But for AI, the discarded information may be its interference. A certain degree of distortion will highlight other truly critical information...

" "Our group's project has verified this point - if these three technologies are combined, only for cancer, the combination of the three can increase the accuracy of judgment by two orders of magnitude."

"I think this is very important for those with mild symptoms, or in the earliest stages of the disease. After all, early diagnosis means more opportunities..."

There was an awe-inspiring silence in the headset.

After a few seconds, the questioner's voice softened a lot: "Yes, this is indeed a very convincing consideration. Thank you, Professor Su..."

Gong Shaowen, Su Yunbai's old subordinate, cleared his throat: "Minister Su... Professor Su, you just said that your team has verified the combination of these three?"

Su Yunbai laughed.

Minister Gong was still as direct as ever.

She said, "Yes, I have the code, but it's a rough version with manual input and output, and it's only for specific cancers..."

"I can make these codes available to you. You can add fiberized information on this basis, retrain AI, and package the transmission interface between the three technologies..."

Huo Qinian came back to his senses, "Professor Su, I will discuss this with you later."

The meeting lasted more than three hours. It gets dark earlier in winter. By the time everyone got up from their computers, it was already dark.

The people who followed Huo Qinian tactfully left the study, saying that they were going to prepare dinner.

After everyone left, Huo Qinian put down his computer and walked over to Su Yunbai.

Su Yunbai handed him a USB flash drive: "This is the code."

Huo Qinian took it and said, "The Huo family will pay for the intellectual property rights."

Su Yunbai glanced at him and said, "There's no rush for this. Use it first. Anyway, part of it is supported by your funds."

Huo Qinian looked at her and said nothing.

The study suddenly fell into an unsettling silence.

After a long while, Huo Qinian seemed to have finally gathered up his courage.

He said, "Yun Bai, I'm going back to China."
