Threatening the big devil? How is that possible?

The big devil has been scared since he was a child and it is impossible for him to be scared.

As for Demon King Shen, he seemed to be a little trembling.

Doctor Jin, who was standing shoulder to shoulder with him, also had his shoulders trembling.

I just saw Dr. Xie in front waving to the two of them: Come up.

Asking you to take a look first does not mean that you are not allowed to do it. Otherwise, I will just ask you to get out of the operating room.

Why would someone who can't work stay in the operating room?

Dr. Xie is actually often so domineering that people only realize it after a while.

Doctor Shen and Doctor Jin were muttering in their hearts: Why does this junior sister like to keep a low profile on weekdays?

...

...

After all, they are the big bosses, how can they show fear in front of a bunch of useless young juniors (don’t forget that Rabbit Li is there watching them), and walk forward.

"The intubation procedure is the same." Dr. Xie Wanying said the first sentence.

The boss would never say a word of waste, and this is especially true for Boss Xie.

Boss Xie continued, “Electric field positioning, magnetic field positioning, you have all come into contact with them.”

Today's machines are just a combination of the two. What changes can be made? At least the basic principles of physics cannot be changed.

Dr. Shen and Dr. Jin were like two elementary school students, trying hard to digest every word of Teacher Xie's on-site instructions.

The scene in front of them first made the young doctors stare in amazement.

A young doctor training a big boss? Only Dr. Xie can do that.

"Positioning film, magnetic patch--" The two good students immediately responded to the teacher's instructions, and Dr. Shen spoke first.

"Everything is there. I've applied them to the patient," said Dr. Xie Wanying.

Magnetic field positioning requires environmental equipment like MRI, which is: the coil in the positioning piece generates a magnetic field, and the magnetic patch attached to the patient's back forms a corresponding signal with the positioning piece, which can be used as the starting point of the system positioning reference.

It was their negligence that they didn't notice what Boss Xie did from the beginning.

The big devil Zhang snorted secretly and became sullen. He thought he had caught classmate Xie off guard, but it seemed that he was counterattacked by Deputy Leader Xie, which made him panic.

"Are there electrical sensors and magnetic sensors in front of the catheter?" It was "Student Jin"'s turn to ask Teacher Xie.

The two students were very smart. Teacher Xie nodded and said: I don’t need to give any more lectures next.

Generally speaking, this technological upgrade has little to do with the doctor's manual operation. The intubation process is the same from two-dimensional positioning to three-dimensional positioning. The only difference is the software and hardware upgrade of the catheter device, adding various sensors to the catheter head.

The electric sensor added for electric field positioning, the magnetic sensor added for magnetic field positioning, and the sensors added for electromagnetic dual positioning include the above two types.

When it comes to the three-dimensional construction software stage, the electric field positioning system relies on electric positioning, the magnetic field positioning system relies on magnetic field positioning, and the electromagnetic dual positioning system relies on electric field positioning plus magnetic field positioning, which means that the two are calibrated with each other for greater accuracy.

Electromagnetic fusion positioning is necessary because electric field positioning or magnetic field positioning alone has its defects and inaccuracies. For example, electric field positioning is prone to produce electrical signal deformation, which is caused by the different impedances of various tissue structures in the human body.

Doctors Jin and Shen continued to stare at the machine, knowing that designing this thing might not be easy.

The conversion of magnetic field transmission signals and electric field transmission signals into three-dimensional image points requires computer programming. How to develop a more reliable calculation method that can be applied to all patients as much as possible is equivalent to pursuing an axiom.

Unlike other industries, this kind of software design involves human life and so various clinical experiments must be conducted. The intervention of clinicians can play a vital role in corrective guidance.

The machine used today is obviously different from the robotic arm calibration that Sister Xie has demonstrated before. Compared with the high degree of spatial freedom of the robotic arm's automated calibration outside the human body, this is a positioning calibration inside narrow and complex organs with low degrees of freedom and higher calibration accuracy requirements.

Considering this, Dr. Shen put his hands on his hips and thought carefully.

Doctor Jin turned around and went out to wash his hands again, ready to go on stage at any time.
