Chapter 1674 The First Step of the Long March
Time flies in the busyness, and Saturday is here in the blink of an eye.
Because he has been working for half a month, this Saturday is also Yu Zhiming's rest time.
It was a rare two days off in a row, and Yu Zhiming got up nearly an hour later than on weekdays.
After washing up, Yu Zhiming went downstairs and saw Qing Ning acting coquettishly beside his mother-in-law Lu Hong.
"husband……"
Seeing Yu Zhiming's Qing Ning, she left her mother-in-law and jumped into Yu Zhiming's arms.
"After breakfast, I'll go with you to see the ultrasound echo machine, okay?"
Yu Zhiming was just thinking about how to answer when he heard his mother-in-law's voice, "Zhiming went there for work, why are you running around with him?"
"Besides, you never know when pregnancy symptoms will come. Before they come, you should eat and replenish your body to build a good foundation."
Qing Ning pursed her lips and said to Lu Hong, "Mom, then I won't be with you during the day. I'll go to Director Qi's youngest son's full moon banquet with my husband tonight. Should that be okay?"
Lu Hong directly refused: "That's even worse."
"The food at the banquet is heavily seasoned, and the ingredients are likely not fresh, which is not good for the fetus. Just stay home and eat the nutritious meals I prepare for you."
These words made Qing Ning twist and turn unwillingly in Yu Zhiming's arms, making an aggrieved "engeng" sound from her mouth.
Lu Hong was a little embarrassed to watch and criticized, "What are you humming? Gu Qingning, just because you are pregnant doesn't mean you have become a three or five-year-old child. Grow up a little."
Yu Zhiming smiled dotingly, stretched out his finger and tapped Qing Ning's eyebrows, saying: "I don't have any plans for tomorrow. If you behave at home today, I will take you out to play tomorrow!"
"Is it a deal?"
"It's hard to catch up with the old man..."
After breakfast, Yu Zhiming, accompanied by Zhou Mo, took a Phantom and arrived at a factory building in the southern part of the city at around nine o'clock in the morning. The factory building looked quite old.
Yu Zhiming met up with Gu Qingran, who had arrived earlier and was waiting at the gate. He followed him into a large factory building that required access control, and was shocked to discover that there was a different world inside.
The spacious space of one to two thousand square meters is as bright as day and is divided into several functional areas.
There is an office area with thirty or forty desks, and a work area with a dozen or so various processing machine tools.
There is also an accommodation area with simple wooden houses up to three stories high.
Yu Zhiming was somewhat surprised to see the activity and entertainment area with four ping-pong tables.
In addition, he also saw three 40-foot-long temperature-controlled containers.
"Doctor Yu..."
Yu Zhiming looked in the direction of the voice and saw Qin Zhen, an ultrasound researcher in a white research coat, and a middle-aged man with a flat head, coming towards him, surrounded by a dozen people.
Yu Zhiming also took two quick steps, took the initiative to shake Qin Zhen's hand, and said, "Researcher Qin, thank you for your hard work."
Qin Zhen, who looked thinner, sighed, "I really want to say it's not hard, but that would be too insincere."
"For the past few dozen days, my team members and I have been living and eating here, working day and night. How can it not be hard?"
"Fortunately, my hard work has paid off. I finally got some results. I'll need Doctor Yu to examine them carefully later."
Yu Zhiming stated: "Everyone's hard work will not be in vain and will be duly rewarded."
Yu Zhiming then shook hands with the middle-aged man with a flat head and said, "Thank you for your hard work."
He already knew that the middle-aged man in front of him was the technical director sent by the military for support.
Without the strong support of the military technical team, this ultrasonic whole-body diagnostic device would not have achieved results so quickly.
The middle-aged man chuckled and said, "Seeing this whole-body ultrasonic diagnostic device put into use, allowing our country to occupy an important position in the world of high-tech medical equipment, all the hard work and efforts are worth it."
Yu Zhiming nodded and said, "It won't be too long. This day will come soon..."
Next, Yu Zhiming, led by Qin Zhen and others, walked into a container and his eyes widened.
It turns out that there is an instrument inside the container.
Yu Zhiming actually knew that CT and MRI machines were also quite large in size.
What patients usually see is only part of the instrument.
When hospitals place these large medical instruments, they need to have special rooms.
In Yu Zhiming's opinion, the hospital needs to prepare a large room to install this instrument.
Qin Zhen introduced: "This is the test machine of the ultrasonic whole-body diagnostic device we have currently developed."
"Because it's a test machine, we're mainly concerned with its functionality, not its size or appearance."
"Once the functions are perfected, we will consider its size and appearance. It must be easy to produce, install and use."
"Preliminary estimates suggest that when it is finalized, it will be half or even one-third of its current size."
Yu Zhiming let out a soft "oh" and looked at the sink-like component in front of him that could accommodate one person and was filled with colorless liquid.
"The patient is going to lie down in here for an ultrasound?"
"Is this water or oil?"
"Do you want to get naked while lying in there?"
Qin Zhen explained: "We developed a liquid with a certain ratio, which is similar to oil. The attenuation of ultrasound waves in it is almost zero, and it is harmless to the human body."
"You need to take off all your clothes during the inspection."
Yu Zhiming asked again, "Is it harmless if I drink it? Is it easy to clean? Do we need to change the liquid after each examination?"
“Also, is the cost high?”
Qin Zhen replied, "It's colorless and tasteless, so drinking it isn't harmful. It should be easy to clean, too."
"To avoid cross infection, this liquid needs to be changed after each inspection, but it can be reused after filtering and disinfection."
"We've roughly estimated the cost of reuse, and it should be around 50 yuan per person."
Yu Zhiming nodded.
Because this test machine would make quite a loud noise when turned on, Yu Zhiming was not allowed to use it.
Next, Yu Zhiming came to the main purpose of his visit today, the ultrasonic echo collector.
It is not small in size and takes up half of a container.
As soon as Yu Zhiming entered the container, he noticed something different and it instantly became much quieter.
"Is this place soundproofed?"
Qin Zhen softly explained, "To avoid interference from noise and ensure we capture even the subtlest ultrasonic echoes, we've implemented professional soundproofing."
Yu Zhiming hummed and said, "I don't understand this instrument either. Let's just test its echo collection effect..."
Following his words, everyone except Qin Zhen retreated.
The moment the heavy soundproof door of the container was closed, the noise outside disappeared immediately, and Yu Zhiming had an illusion that he was expelled from the outside world.
Qin Zhen, who stayed behind, gently pressed the switch of the instrument, and immediately a buzzing sound arose.
She looked at Yu Zhiming with concern and saw that his brows were furrowed and his face was full of patience.
Fortunately, the roar lasted for more than ten seconds, then quickly slid down and finally maintained at a lower level.
Qin Zhen noticed that Yu Zhiming's brows slowly relaxed, and she secretly breathed a sigh of relief.
"Doctor Yu, our preparations were a bit hasty. Next time you come, we'll isolate the sound from the main unit and the acquisition probe. That way, you'll feel much more comfortable."
Yu Zhiming nodded, and then saw Qin Zhen lying on the examination bed, lifting her clothes to reveal her lower abdomen.
"Researcher Qin, what are you doing?"
Qin Zhen explained with a puzzled look on her face, "It's an ultrasonic echo acquisition. You perform an ultrasound on me and then check the echo acquisition results."
Yu Zhiming rolled his eyes and said, "I don't need to do on-site data collection. You just need to play back the ultrasonic echoes collected in the previous experiment."
Qin Zhen let out a light cry, turned over and got off the examination bed, and turned off the machine first.
Feeling a little hot on her face, she said awkwardly, "If we only listen to the echoes collected previously, there's no need to turn on the instrument. The echoes collected in the previous experiments are all stored in the computer."
Qin Zhen turned on the desktop computer in the container, called up the test database, and clicked on an audio file.
After clicking it, she set it to loop playback mode.
After doing all this, Qin Zhen looked at Yu Zhiming, only to see him standing there motionless with his eyes slightly closed.
At this moment, Qin Zhen could no longer hear any sound except for the slight noise coming from the desktop computer.
However, she knew that there were sound waves that she could not hear, echoing in the container through a speaker that could be said to be the most precise and high-fidelity in the country.
Qin Zhen not only stood still, but also slowed down her breathing and heartbeat, fearing that she would disturb Yu Zhiming...
The extremely familiar subtle sounds gathered in Yu Zhiming's mind, like various materials, constructing models of one organ after another.
Uterus! Ovaries! Corpus luteum! Fallopian tubes!
Kidneys! Bladder!
Part of the intestine!
Reproductive tract...
At first, the organs were just outlines, but as the sounds continued to flow in, they quickly became three-dimensional and clear.
To Yu Zhiming, it felt like the resolution was constantly being refreshed, from the initial blurred mosaic outline...
Then to 120P...
240P……
480P……
720P……
Yu Zhiming listened for a while longer and found that the clarity could not be improved any further, so he knew that this was the end of it.
However, he was already very satisfied, as the clarity of the images was not much different from that of the ones he had constructed by himself.
When Yu Zhiming opened his eyes again, he met Qin Zhen's nervous gaze.
"Very good. The clarity of the echoes collected exceeded my expectations. There is no problem in putting it into practical use."
Yu Zhiming commented and said, "Well, tell that volunteer not to be so rude."
"The corpus luteum has slightly ruptured, and the reproductive tract has also been torn, which is not good for the body."
Qin Zhenteng's face flushed red as he murmured, "I'll definitely tell that volunteer to pay more attention..."
When Yu Zhiming opened the soundproof door of the container, he saw thirty or forty people quietly guarding outside.
Before Yu Zhiming could speak, Qin Zhen shouted, "Doctor Yu said..."
Qin Zhen's voice rose two notches. "The original words were, 'Very good! The clarity of the collected echoes exceeded his imagination. There's no problem putting it into practical use.'"
Yu Zhiming nodded as he faced the dozens of eager eyes that were cast upon him again, saying, "That is indeed my evaluation."
Before he even finished his words, the place became boiling with dozens of people either jumping and dancing or hugging each other enthusiastically.
Gu Qingran came close to Yu Zhiming and said with emotion, "This must be the first successful step in a long journey."
"What do you think next?"
Yu Zhiming knew that this ultrasonic echo collector was just a tool to prepare for the next step of work.
Data collection and the establishment of a comprehensive disease database are the core and key to making ultrasonic whole-body diagnostic equipment a powerful tool for disease diagnosis.
This step is long and boring.
The important thing is that Yu Zhiming cannot delegate the task to others.
Yu Zhiming sighed softly, "What else can I think of? I'll just work hard like an old ox, day by day, slowly collecting data."
"There will always be a day when it will be completed, but I can't say when that day will be."
"Maybe in five years! Maybe in ten years!"
Gu Qingran laughed and said, "We have an idea. We should focus on one organ first, such as the heart."
"We spent several months collecting ultrasound echo signatures of various heart problems and building a heart disease database."
"We have temporarily downsized this whole-body ultrasound diagnostic device into a cardiac ultrasound diagnostic device and are launching it on the market for trial."
Yu Zhiming nodded in agreement and said, "That's a great idea. We'll upgrade it every time we complete an organ, and eventually it will become a true whole-body diagnostic device."
"During this process, the instrument itself can also be improved based on problems that arise during actual use."
Gu Qingran smiled and said, "That's what we think..."
What surprised Yu Zhiming was that there was a kitchen in the factory.
The chef had obviously prepared for today and purchased a lot of ingredients for the celebration.
After a brief celebration, the chef called on a few staff members to help prepare a celebratory lunch.
Yu Zhiming discussed the next steps with Gu Qingran, Qin Zhen, and seven or eight core technical personnel.
Since Yu Zhiming only needed to listen to the collected ultrasonic echoes, everyone discussed bringing patients diagnosed with various heart problems here to collect ultrasonic echo data.
Yu Zhiming can conveniently use his own time to listen to these ultrasonic echoes, process the echoes, and edit out the typical echo characteristics corresponding to heart problems.
Not only that, Yu Zhiming also has to draw a schematic diagram of heart disease based on ultrasound echoes and hand it over to the technical team for modeling.
After all, after the ultrasonic cardiac diagnostic device makes a diagnosis, it not only provides the diagnostic results, but also produces imaging images to facilitate the attending physician in formulating a treatment plan.
It is somewhat time-consuming and laborious for Yu Zhiming to draw a map of heart disease. The technical team said that they can first build a heart model based on the patient's heart ultrasound test data.
Yu Zhiming only needs to draw the specific condition of the disease on this heart model...
Yu Zhiming stayed in the factory until after three in the afternoon before leaving with Gu Qingran and others. In addition to having a celebratory lunch together, they also discussed issues with the technical staff.
If Yu Zhi hadn't had an appointment tomorrow morning, it's possible that everyone would have continued discussing it until the evening.
The person who had an appointment with Yu Zhiming and Gu Qingran was a retired medical expert from Union Hospital.
They want to discuss Zhai Yan's Life No. 1 medical AI...
