The next day, I came to Fangze and met Dr. Sun, only to find out that she was a female boss in the radiology department.
"Doctor Xie Wanying." Many female teachers in the hospital are very generous. When they saw her, Doctor Sun directly took her hand as if she was an aunt talking to her own daughter, and they became very close.
This scene made the other male doctors at the scene want to smash the pot. They never knew that female teachers had such advantages.
"Do you know what the machines in our hospital are like? Tell me what you have heard about them," Dr. Sun encouraged.
Since she would be helping Professor Sun with his work, Xie Wanying discussed academic issues with him seriously: "I have only seen some relevant reports in some medical journals."
No matter how the Gamma Knife changes, we must first know that the Gamma Knife has one thing in essence that remains unchanged: it uses gamma rays. Gamma rays are not mysterious, they are the "y" (gamma if you can't type the letter) rays emitted by cobalt 60.
Who invented gamma rays? It was Marie Curie, the famous two-time Nobel Prize winner.
Therefore, the reason why Xie Wanying was more interested in learning about the Gamma Knife before her rebirth was because the Gamma Knife was an extension of the story of Marie Curie.
It was very difficult for women to win a Nobel Prize. Marie Curie won two awards, which made her a rare female leader in the scientific community. She had admired her since she was a child. She once thought that if she couldn't be a doctor, she could study physics and chemistry like Marie Curie, which would also benefit the world.

Here comes some cool trivia: the founder of the Gamma Knife was a neurosurgeon, and he is also the founder of the company that now provides Fang Ze with the Gamma Knife.
The advantage of having a doctor as an inventor is that the medical tools they create will be more practical because the doctor himself has a better understanding of the clinical status quo.
I heard that the history of the creation of the Gamma Knife is exactly like this. Neurosurgeons at that time found that the mortality rate of neurosurgery with craniotomy was a bit high, so they considered using a non-craniotomy method to eliminate tumors in the brain.
"In the fourth generation of gamma knife, 201 cobalt-60 radiation sources were used."
As mentioned above, the founder is a neurosurgeon who is very familiar with clinical practice and knows that the characteristics of brain treatment are to avoid harming the functional area and to kill the tumor as much as possible, so as to avoid leaving patients with postoperative sequelae that are worse than death. Therefore, the upgrade of the Gamma Knife is mainly centered around the technical transformation of the radiation source, which can be called the "knife" of the Gamma Knife.
The radiation source can be regarded as the flying knife in Xiao Li's Flying Dagger. It is shot out from the machine, which is equivalent to flying out from Xiao Li's hand. Use such a "knife" to shoot the tumor and eliminate it.
A major feature of the "flying knife" is that it must fly. If it flies, it is much more difficult to make it accurate than to operate it directly at close range. The consequences of inaccurate flying are terrible. Under this premise, the founder, a neurosurgeon, can think of making the flying knife smaller to improve its safety, and would rather use multiple flying knives to shoot like flying needles. In theory, the energy effect of multiple needles will not be much worse than the energy value of using a single knife, and it can be more accurate.
How to be precise? The flying needles close to normal tissues can reduce the killing energy value, which can minimize the damage to normal healthy tissues. For the center of the tumor, more flying needles are gathered to amplify the killing energy and completely eliminate it.
"Another feature of the fourth-generation gamma knife is that it has an advanced computer control system APS," Xie Wanying continued to add.
