Chapter 539 Digital Human Project

After sending Professor Liang away, Yang Ping returned to the hospital, sorted out the materials, and brought them to the patient room for distribution.

Huang Jiacai was already waiting downstairs. They were going to the Digital Medicine Laboratory of Nandu Medical University.

This laboratory has been researching the "digital human" project, but it was difficult to continue the research because of the shortage of funds.

Huang Jiacai took the initiative to find Professor He Jirong, the director of the laboratory, and proposed to establish a cooperation, and Ruixing Company will provide continuous research funds.

At that time, Professor He was very skeptical that "digital human" was a basic medical research, and no company was willing to invest money.

This kind of purely basic project cannot generate profit, and the enterprise has no interest.

Enterprises like projects that are short, flat and fast, and can make money quickly.

At that time, Professor He wondered whether Boss Huang had other intentions. When Huang Jiacai showed him the cooperation agreement, there was no clause requiring profit, but only the sharing of the results of the cooperation project.

The prudent Professor He took the agreement back to discuss for several days, and then with the attitude of trying, he met with Huang Jiacai again, and the two signed the agreement.

After signing the agreement, Huang Jiacai made a phone call on the spot, and the Nandu Medical University account left by Professor He received the first scientific research fund from Ruixing Company - 2000 million.

2000!

Just give it as you say, Professor He was a little dazed at the time.

At that time, Professor He saw Huang Jiacai's sincerity and courage, and felt that his project had hope.

This is the first time Yang Ping has met Professor He, and it is also the first time he has used Professor He's "digital human" technology.

Yang Ping will use the "digital human" technology to establish a dynamic model of Fang Faquan's motion system.

Then use the computer to optimize the line of force, calculate the position and direction of the osteotomy, determine the pinhole position of the external fixator, and dynamically simulate the correction process.

For these simulations, Yang Ping can use experimental bodies in the system space.

However, the experience gained in the system space can only become his personal surgical reference, and he is not satisfied with this.

He wants to elevate these experiences into science and technology, which can promote medical progress.

Then, the use of computer for surgical simulation is the best choice.

If the data obtained in the system space can be used for computer modeling, then computer simulation technology will become very accurate.

Professor He is already waiting at the entrance of the experimental building. There are many laboratories in this experimental building, and the digital medicine laboratory is just one of them.

The respect for Huang Jiacai and Yang Ping is not because Professor He bowed his head to the sponsor, but because Huang Jiacai, the boss with a high school education, is really far-sighted and respects Professor He and the researchers very much.

Professor He and Huang Jiacai have become close friends.

Huang Jia brought Yang Ping here today, and he must have attached great importance to it.

Of course, he still doesn't know the true relationship between Yang Ping and Huang Jiacai.

The digital medicine laboratory only occupies half a floor on the third floor. After introducing each other and exchanging pleasantries, Professor He brought Yang Ping and Huang Jiacai to their usual office.

"If it's convenient, can we start modeling now?" Yang Ping proposed to start working as soon as he sat down.

"Yes, I'm ready. Mr. Huang said that Professor Yang needs to build a model of the walking function of the lower limbs this time. We have already perfected the simulation of the lower limbs function. There was no digital human function module before, and the construction of this kind of model did not take a few months. Time will definitely not be completed, now there are digital human lower limb functional modules, on this basis, adding the external fixator module, the modeling can be completed in a few days, and after these modules are maturely matched, the modeling can be completed in a few hours." Professor He I am very happy that someone uses his technology and feels a sense of accomplishment.

Huang Jiacai said to Professor He: "Professor He, you can just call me Xiao Huang, don't call me Mr. Huang, it seems to be born."

Professor He felt very good about this young man, and immediately said: "We had just entered the simulation of lower limb function before, and there was a difficulty in funding. It happened that Xiao Huang was generous and gave 2000 million. We worked hard and just completed the walking function modeling of lower limbs not long ago. .”

At present, digital humans are still at the stage of anatomical humans, and only the motor functions of the lower limbs have entered the stage of functional humans.

Professor He asked a graduate student to take Fang Faquan to the sports information collection room.

Professor He, Yang Ping, Huang Jiacai, and several graduate students are in the computer room next door.

The two rooms are separated by a glass wall and connected through a small door.

The graduate student told Fang Faquan to act according to the instructions, explained each instruction clearly, and showed Fang Faquan a demonstration.

The young man is quite smart and has good receptivity, and he quickly learned how to follow instructions.

There are many sensors on the floor of the sports information collection room and on Fangfa’s body. There are high-definition high-speed cameras at different angles on the ceiling and walls to capture the movement status of different sides.

First walk slowly, then run forward, then jump, stop suddenly, and turn.

Each movement state needs to capture many dynamic pictures.

On the screen in the computer room, a model man was shown doing exactly the same movements as Fang Faquan.

This manikin is a stripped human body movement system, only bones, joint capsules, ligaments, muscles and tendons, etc.

This image is composed of Fang Faquan's CT [-]D reconstruction of bones, MRI reconstruction of muscles and tendons, etc., combined with digital human modules.

After Fang Faquan's motion information was collected, the screen was divided into two halves.

Half of them are still models of lame Fang Faquan, and the other half are models of normal Fang Faquan.

The latter model is produced by modifying the former model.

Then use animation to demonstrate the dynamic process from deformity to normal.

Yang Ping explained to Professor He and graduate students the methods of surgical intervention, the information that surgeons need to obtain, and how the model can assist surgeons.

These people are all masters and doctors with high IQs, computer graduate students with medical background, and they can quickly understand what Yang Ping said.

In the process of orthopedics, they added the influence of the external fixator model, and then found the best distraction core line, which is the osteotomy line.

According to biomechanics, find the best distribution point of the pinholes of the external fixator.

Then let the external fixator stretch to complete the deformation from deformity to normal.

"Give us three days, and we will give you a satisfactory digital model." Professor He was very confident after hearing this.

The combination of digital technology and clinical practice exerts great power.

"If we have an independent supercomputer in the future, this project will progress faster."

Owning a supercomputer is Professor He's dream.

Huang Jiacai encouraged the professor: "Take your time, in the near future, we will have everything, not to mention supercomputing, even supercomputing clusters will also be realized."

This project is the most basic project in Huang Jiacai's plan, and he will pool funds to support this project.

At present, the company is short of funds and can only provide so much. After earning money, it will continuously inject funds.

"If the funds are sufficient, we can expand the research team and be able to complete the modeling of the motor functions of the lower limbs, spine and upper limbs within one year. Among the three, the most complex is the upper limbs, especially the functions of the hands, which will take a long time. "Professor He is full of confidence.

"Professor He, you can study with peace of mind in the future, and tell me directly if you have any difficulties. We will continue to support this project." Huang Jiacai gave Professor He a reassurance.

Professor He didn't doubt Boss Huang's strength at all: "Xiao Huang, with your words, I feel relieved. To tell you the truth, our kind of basic project is most afraid of being half abandoned."

Computer assistance in medicine will play a pivotal role in the future.

For this kind of orthopedics, if the operation is guided by experience, it is difficult to achieve the desired effect.

With computer simulation, everything becomes very easy.

In the system space, Yang Ping can rely on a large number of case simulations to achieve the ultimate in surgery. He has always hoped that he can achieve the ultimate in surgery without the system. This is what Yang Ping pursues.

The system is just a tool for him, and now he wants to make a system for every doctor.

Digital humans can help Yang Ping achieve this goal.

If one day, the digital human can realistically simulate the human body in terms of anatomy and function, all patients can use the digital human to model and simulate the operation, and then combine the data with surgical robots or computer-aided equipment to make the operation easier. Effortless and precise.

In the future, digital humans can be combined with virtual reality technology to develop a doctor training system, allowing doctors to repeatedly train certain operations.

With digital humans as the core, many technologies can be developed.

In this way, every doctor has a powerful plug-in.

Yang Ping and Professor He continued to discuss the details of Fang Fa's full lower limb function modeling.

In the digital medicine laboratory of Nandu Medical University, Yang Ping stayed all morning, and at noon, Huang Jiacai treated Professor He and all the researchers in the laboratory to dinner.

Professor He was very excited at the dinner. Intellectuals only pursued it—concentrating on scientific research.

Now someone has invested in him, and respects him very much, without making any demands, and does not interfere with scientific research.

Don't those who do research just dream of this state?

Professor He has already decided to cooperate with them. It is meaningless to judge or win awards.

As long as there are funds for scientific research, it doesn't matter if he devotes his life's energy to it.
