  "Dr. Xie Wanying." Many female teachers in the clinic are very forthright people. Seeing her, Dr. Sun took her hand directly, like an aunt looking at her daughter and talking homely, and getting close to her.

   This scene made all the other on-site male doctors want to smash it. Never knew female teachers had this advantage.

   "Do you know what the machines in our hospital are like? What have you heard? Let me tell you all about it." Dr. Sun encouraged.

  Because she will help Teacher Sun with her work, Xie Wanying and the teacher carefully communicated and negotiated academic issues: "I just read some related reports from some medical journals."

  No matter how the Gamma Knife changes, you must first know that the Gamma Knife is essentially unchanged, and it uses Gamma rays. Gamma rays are not mysterious, they are gamma rays emitted by cobalt-60.

  Y-ray who invented it? It is Madame Curie, the famous two-time Nobel Prize winner.

   Therefore, Xie Wanying was more concerned about learning about Gamma Knife before she was reborn, because Gamma Knife is an extension of Madame Curie\'s story.

  It is difficult for women to occupy a seat in the Nobel Prize. Marie Curie has won two awards and she can definitely be regarded as a rare female boss in the scientific world, and she has been admired since she was a child. She once thought that if she could not be a doctor, studying physical chemistry like Madame Curie could also benefit the world.

  Here comes the cold knowledge. The founder of Gamma Knife is a neurosurgeon, and he is also the founder of the company that provides Fang Ze Gamma Knife.

  The advantage of a doctor as an inventor is that the created medical tools will be more realistic, because the doctor himself has a better understanding of the clinical situation.

  The history created by Gamma Knife is said to be exactly like this. Neurosurgeons at that time found that the death rate of neurosurgery with craniotomy was a bit high, so they considered using a method without craniotomy to eliminate tumors in the brain.

   "The fourth-generation Gamma Knife uses 201 cobalt-60 radioactive sources."

   As I said, the founder is a neurosurgeon who knows the clinic very well, and knows that the characteristics of brain treatment are that it is best not to damage the functional area and kill the tumor as much as possible, so as to avoid leaving postoperative sequelae that would make life worse for patients. Therefore, the upgrade of the Gamma Knife mainly revolves around the technical transformation of the "knife" whose radioactive source is called the Gamma Knife.

  The radioactive source can be regarded as the flying knife in Xiao Li\'s flying knife. When it is shot from the machine, it is equivalent to flying out of Xiao Li\'s hand. Using such a "knife" to shoot the tumor to destroy it.

   One of the characteristics of "Flying Knife" is that it needs to fly. If it is to fly, it is much more difficult to make it precise than to operate it directly at close range. The consequences of flying inaccurately are dire. Under such a premise, the neurosurgeon founder can think of improving the safety of flying knives by making the flying knives smaller, and would rather shoot more flying knives like flying needles. Theoretically speaking, the energy effect gathered by multiple needles will not be much worse than the energy value of a knife, and it can be more precise.

  How to use the precise method, the flying needle next to the normal tissue, lowering its killing energy value, can minimize damage to normal healthy tissue. For the middle part 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 should be that it has an advanced computer control system APS." Xie Wanying continued to add.

   Thank you for your support! ! good night dears~
