"Master, how do you see nerves and blood vessels at the MRI level? I think it's difficult to see these two structures clearly." Wang Huan explained his doubts after answering some of Zhou Cheng's questions.
"Senior Brother Peng Lingli and Senior Brother Guo Lin also find it extremely difficult to see the shape of nerves and blood vessels." In order to explain that he was not trying hard, Wang Huan pulled these two out for comparison.
First, look at the report, secondly, look at the lesions, thirdly, look at the anatomy, and fourthly, look at the layers...
By being able to see the anatomical layers, you can distinguish the shapes of different tendons and muscles, such as ligaments, muscles, etc.
But if you want to see the level of nerves and blood vessels, you need to read the original MRI film more carefully!
This kind of in-depth content can no longer be read by doctors in the imaging department, and even specialists with insufficient skills cannot see the corresponding distortion.
It requires not only basic anatomy skills and film reading skills, but also some more professional knowledge to assist.
To be honest, this is a hard work in MRI reading of hand surgery. At present, there is no shortcut.
Zhou Cheng was able to help Wang Huan list the approximate levels of different levels, and he had already spent a lot of time: "To see the shape of nerves and blood vessels, in addition to basic professional skills and anatomy knowledge, you also need to have an in-depth understanding of the basics of magnetic resonance imaging.
principle."
"We know that nuclear magnetic imaging mainly relies on the relaxation effect of HO..."
"The display characteristics of nerves in MRI: Nerves usually appear as areas of high signal intensity. This is because the lipid myelin sheath around the nerve has a high repellency of water molecules, causing the surrounding tissue signal to be lower than the nerve signal.
"The imaging principle is: the display of nerves mainly relies on T2-weighted imaging, that is, under certain scanning parameters, the T2 value of neural tissue is longer, so neural structures with high signal intensity will be displayed in T2-weighted imaging."
"Display characteristics of blood vessels: Blood vessels usually appear as low signal intensity areas. This is because the oxygen hemoglobin in the blood inhibits the generation of MRI signals, and the lipid myelin around the blood vessels also inhibits the generation of signals.
"Imaging principle: The display of blood vessels mainly relies on T1-weighted imaging, that is, under certain scanning parameters, the oxygenated hemoglobin in the blood has a longer T1 value, so vascular structures with low signal intensity will be displayed in T1-weighted imaging.
This is different."
"So we usually look at nerves at the T2-weighted level and blood vessels at the T1-weighted level. This requires a lot of practice..."
"There are no shortcuts when it comes to learning, but there are certain shortcuts. This is slightly related to the way we humans learn. You can form your own unique corresponding anchor points when reading pictures."
"Do you know what a learning anchor point is? It's a tool to assist you in learning, just like the spatial memory method and the palace memory method. Looking for a substitute-"
"For example, some people are great masters in the mathematics department. Some people are very sensitive to the three-dimensional structure of space. Therefore, they are very keen in learning number theory and imaginary and real numbers!"
"There are also people who study art and have a strong sense of three-dimensionality..."
"There are also people who are sensitive to words..."
"There are also people who are very familiar with refining. They can quickly dismantle the key parts of a large article, and after reading it, they can restore the general meaning. This is sensitivity to words."
"This kind of person has a natural learning advantage. He can memorize many concepts and content, and then when he understands them, he is very good at writing articles. This is organizational ability."
"There are also some people who are sensitive to numbers. It may be difficult for them to memorize some words alone."
"But once it is linked to the numbers, they will be able to remember them for life. Even when they speak, they may have to extract the numbers first."
"There are also some people who structure the knowledge system into a spatial structure and place different things on different nodes."
"That's the anchor point for learning."
"If you can list the nerves, blood vessels, muscles and tendons into different objects during the process of reading the film, and find a relatively exaggerated pictogram or substitute, then the next time you read the film, you will see
These things will stand out in front of your eyes more clearly."
"It's like, Wang Huan, are you afraid of mice?"
When Wang Huan heard this, he suddenly got excited and shook his head violently. It seemed that upon hearing this word, he had formed a memory of fear in his muscles, and his expression was horrifying.
Seeing this, Zhou Cheng said: "Yes, that's it. As long as it is a mouse, whether it is a picture, text, related words, its cry, etc., you can react immediately. If you can read
Some parts of the film are intended to be related to these, so when you read the film in the future, the first thing you will discover is these memorable things."
"Master, can you not compare nerves and blood vessels to that mouse?" Wang Huan himself doesn't like to say this word, so he uses English instead every day.
"Okay, you can replace it however you want. I'm just giving you an example."
"Well, I asked Yang Yifeng specifically for you. This is how he learned it. His memory method is a compass, and of course it's not just a compass. He is very sensitive to the structure of the plane. He can even combine a large number of
The article is stored in the memory in the form of a polycyclic circle and can be retrieved like this at any time."
"I never thought I could learn like this." Zhou Cheng smiled bitterly.
The gap between geniuses and ordinary people is huge. Zhou Cheng's ability to have such a profound knowledge reserve can be said to be either a trick or the accumulation of time. Zhou Cheng has been immersed in the simulated world for who knows how many years, all by rote memorization.
Memorize it hard and rely on cheating to complete the directional memory of some things.
But Yang Yifeng is different. His time is limited. Although his current knowledge reserve is not as good as Zhou Cheng's, his learning efficiency per unit of time is many times that of Zhou Cheng's.
And although Zhou Cheng copied other people's talents, the same was true for An Ruo.
But their talents have only improved slightly in recent years. People like Yang Yifeng have already been like this before, so they have accumulated a lot of things, but if they don't show it on weekdays, most people don't know it.
"Thank you, Master." Wang Huan also knew that the teacher had put a lot of effort into his studies.
"By the way, Master, the two senior brothers and I have already downloaded the closed beta version of the app you asked us to download. The two senior brothers also gave us some feedback. He said, if you want this game to be more interesting, you can
Create a skills exchange system.”
"For example, if a player has any skills, they can be packaged into skill scrolls and sold, so that other players can pass the level..."
When Zhou Cheng heard this, his expression was wonderful: "They really treat this thing as a game, right?"
"I use it as a learning app, not a gaming app."
Wang Huan nodded again: "Yes, Master, this is a learning app, but the two senior brothers said that if the player still cannot kill the monster after having the skills, then there is something wrong with their operation, so they are looking for a way to kill the monster."
When killing monsters, look for the logic and principles behind the operation."
"This can further stimulate players' desire to learn. After all, in the game you developed, teacher, every surgical step is optional, and the threshold mechanism is set in advance..."
"For example, joint replacement surgery cannot be performed before reaching the proficiency level. It is actually a bit difficult to obtain such a skill scroll. It is better to let other players make a profit, obtain game funds, and get more
Skill."
"At the same time, if other players cannot clear the level even though they have acquired skills, that means they are too bad. Senior Brother Peng Lingli said that the word bad can very much stimulate gamers' desire to learn." Wang Huan relayed it seriously.
.
Zhou Cheng was thoughtful after hearing this.
To be honest, the game Zhou Cheng liked to play before was StarCraft. In the stand-alone computer version, Zhou Cheng could play one against seven.
But when you play against other people, the operation is really not something you can master through practice. Others' APM can reach hundreds per minute. And it's still an effective APM. How can you compare?
Even if you practice too many times, you won't get effective improvement. It requires talent, so it's difficult to get started.
But some games being developed now don’t seem to be like this.
Moreover, the mechanism proposed by Wang Huan and Peng Lingli is not difficult, so it seems feasible.
"Okay, I'll think about it." Zhou Cheng nodded.
"And more," Wang Huan said immediately.
"Senior Brother Guo Lin is involved in games a lot. He suggested to Master that during the public beta, it is better to change the name of the game. Instead of calling it a doctor simulator, it is better to call it a medical persuasion game. It will be more able to attract some unique interests.
player."
"Of course, if your position is not to make money, you can do this." Wang Huan added.
Zhou Cheng suddenly couldn't laugh or cry, what the hell was this Guo Lin, but their suggestions were indeed effective.
But Zhou Cheng's plan was actually more than that.
"You should go back first and look carefully for anchor points or substitutes for nerves and blood vessels during the film reading. I will think about it again," Zhou Cheng said.
To be honest, the reason why Zhou Cheng wants to develop such an app is actually to widely improve the professional capabilities and level of relevant practitioners, and even through this game or app, it can objectively reflect the normal level of a doctor.
Of course, this ambition is a bit ambitious.
If you want to take into account the fun ability, it is a bit putting the cart before the horse, but if there is not a certain number of users, then there is not so much meaning in designing this app.
There are so many recreational games on the market today that only have two elements: monster fighting and skills, and it is difficult to attract people.
Moreover, this app is actually a bit boring from an objective point of view and is not particularly suitable for killing time. Therefore, it may be better to add some worldview and story elements to it.
After all, a mature game should have a storyline.
Thinking of this, Zhou Chengcheng went to Yang Yifeng again and made a phone call: "Yifeng, how do you design the storyline of the doctor simulator? Don't worry, how you design it will determine how the game will be presented in the end, and
You can write and send it at the same time. It’s best if it’s a little more detailed and attractive.”
The plot of the game is a very important part.
"Brother Zhou Cheng, don't worry about this. I'm better at writing games than you. I've prepared several plots. If the protagonists have different initial backgrounds, the storylines they encounter will also be different."
"Let me tell you, I have listed a total of more than a dozen initial identities now, and I have also invited other authors who can write medical stories to help write them."
"Most of them are old doctors from township health centers, with regular training, master's degrees, pharmaceutical agents who have changed their profession, etc."
"Speaking of this, I'm not bragging. I'm much more professional than you." Yang Yifeng was probably not busy with experiments at the moment, so he was very interested.
"I believe this. Thank you for your hard work. I will settle the matter with you when the time comes." Zhou Cheng said.
He had previously offered Yang Yifeng a price of one thousand words and one hundred, thinking it was high enough, but later he found out that if Yang Yifeng wrote more novels of his own, the price would be much higher than one thousand words and one hundred.
It's a pity that Zhou Cheng himself doesn't know much about this.
"It's enough for you to pay my friend some hard-earned money. After all, they used to major in medicine. Although they didn't take this step in the end, they actually hope that this industry will develop better and better."
"Okay, I won't say much more. I also called some people to conduct internal testing. They will give me some feedback when the time comes."
"But Brother Zhou Cheng, one opinion I have received is that in this game, it is best not to make things difficult just for the sake of making things difficult. It is best to set up a simple professional official forum and release some strategies or documents in due course."
“Facilitates communication among colleagues.”
"In addition, another thing is that you have to prepare Brother Quan. I think the next person to ask him to develop a similar game may be a cardiology department. Someone in this field has already asked me."
"What I think is that if the module of cardiology is added, it will be very troublesome, and the treatment principles, professionalism, different skill levels, etc. of different disciplines have to be set by their specialists. If you want to set
I don’t know how long it will take to perfect, and I don’t know if it will be successful.”
"So I think it's better to let them fiddle with it on their own, otherwise it will affect the quality of our game." Yang Yifeng said with some loss.
"Well, okay, we are just doing our orthopedics department, we can't control other departments." Zhou Cheng replied with a smile.
I don’t know how long it will take? I don’t know if it can be successful.
It is almost certain that Zhou Cheng will have a hard time succeeding, because as long as different skills are placed in different professors, they will have different understandings. As for the classification of levels, it requires people who have a very high level of skill mastery to be able to clarify the levels inside.
Unless there are people like me in other departments who can perfect or even redefine perfection in all skills of common diseases, otherwise, this project will definitely not be able to be replicated.
Zhou Cheng can know the workload.
Just by dividing different levels of different skills and re-setting the levels of clinical diseases, there are tens of thousands of entries. The workload and complexity are just kidding...
Yang Yifeng then said: "Brother Zhou Cheng, can I ask you a question? You don't have a deep and thorough understanding of all the common diseases in orthopedics and spine, right?"
"What do you think?" Zhou Cheng asked without answering.
"That's awesome! I'm convinced."
"No more nonsense, I have a call from here." When Zhou Cheng saw Chen Tingye calling, he quickly hung up.
"Professor Chen?"
"Xiao Zhou, can you take the time to come to the operating room in half an hour? We will transfer a patient to our hospital who has undergone amputation. Can you see if we can perform a limb-sparing operation on him...
"Chen Tingye opened his mouth with a request, without any politeness.
