The next day I came to Fangze and met Dr. Sun, only to find out that he was a female boss in the radiology department.
"Dr. Xie Wanying." Many female teachers in clinical practice are very outgoing people. When he saw her, Dr. Sun directly held her hand, like an aunt looking at her daughter and talking about everyday things, getting close to her.
This scene made all the other male doctors at the scene want to blame them. They never knew that female teachers had such an advantage.
"Do you know what the machines in our hospital are like? Tell us what you have heard about." Dr. Sun encouraged.
Since she had to help Teacher Sun work next, Xie Wanying communicated and negotiated academic issues with her teacher seriously: "I have only seen some relevant reports from some medical journals."
No matter how the Gamma Knife changes, you must first know that the essence of the Gamma Knife remains unchanged. It uses gamma rays. Gamma rays are not mysterious, they are Y-rays emitted by cobalt-60.
Who invented Y-rays? It was the famous two-time Nobel Prize winner Marie Curie.
Therefore, Xie Wanying's classmates were more concerned about understanding the knowledge of the Gamma Knife before her rebirth, because the Gamma Knife was an extension of the story of Marie Curie.
It is really difficult for a woman to get a seat in the Nobel Prize. Marie Curie won two prizes and she can definitely be regarded as a rare female leader in the scientific world. She has admired her since she was a child. She once thought that she could not be a doctor and would be like Marie Curie.
Studying physical chemistry can also benefit the world.
Here’s another piece of trivia: the founder of Gamma Knife is a neurosurgeon, and he is also the founder of the company that now provides Fang Ze with Gamma Knife.
The advantage of doctors as inventors is that the medical tools they create will be more realistic because the doctors themselves know the clinical status better.
The history of the Gamma Knife is said to be exactly like this. Neurosurgeons of that era 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.
"The fourth generation of Gamma Knife uses 201 cobalt-60 radioactive sources."
As I said, the founder is a neurosurgeon who has a very good understanding of clinical practice and knows that the characteristic of treating the brain is not to damage the functional area and to kill the tumor as much as possible to avoid leaving the patient with postoperative sequelae that would be worse than death. So Ga
The upgrade of Gamma Knife mainly focuses on the technological transformation of the "knife" whose radioactive source is called Gamma Knife.
The radioactive source can be regarded as the flying knife in Xiao Li's flying knives. Shooting out from the machine is equivalent to flying out of Xiao Li's hand. Use such a "knife" to hit the tumor and destroy it.
A major feature of the "flying knife" is that it has to 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 very terrible. Under such a premise, the founder of the neurosurgeon can think of
To improve the safety of flying knives, you can make the flying knives smaller. It is better to have multiple flying knives like flying needles. Theoretically speaking, the energy effect of multiple needles will not be much worse than the energy value of one knife.
, and can be more precise.
How to use a precise method to reduce the killing energy value of flying needles next to normal tissues, so as to minimize the damage to normal healthy tissues. For the middle part of the tumor, gather more flying needles to amplify the killing energy and completely eliminate it.
"Another feature of the fourth generation Gamma Knife should be that it has an advanced computer control system APS." Xie Wanying continued to add.
