Chapter 3547 [3547] Various considerations
Everyone filed into the control room and gathered in front of the machine screen.
As written in a science fiction novel, the coolest thing about technology is that rows ofplex digital graphics control screens float around on the screen, as if the mathematical soul is flying.
"The operation interface seems to be veryplicated." Dr. Ou Feng stood behind, took a nce at it on tiptoe and said.
I feel that if I haven’t learned it before, seeing it for the first time is definitely like reading a bible.
The more intelligent the machine, the more urate the calcted results must be, and the premise must be more urate in the input data.
How to ensure the uracy of the input data, refer to the previous membrane lung verification link, the best way to obtain each number is to eliminate interference, and it is best to have multiple verification methods to verify.
To do this, for example, the first step is whether the patient should shave their hair or not. In fact, the Gamma Knife does not need to shave the hair, and it is better to cut the long hair short. The obvious advantage of shaving and cutting hair is that it can eliminate interference and help doctors and machines to locate more precisely.
Considering that this patient has as many as seven tumors in his brain, and thetest machine is used for treatment. Anyway, there is a possibility of hair loss after radiotherapy. The patient''s appeal is definitely that it is best to wipe out the tumor at one time, and it is better to simply shave the hair for the most urate positioning.
It is not afraid to shave your hair, the hair will grow back soon. Clinically, the most feared thing is that it will not grow out, such as hair loss and baldness, there is really a possibility that there is no cure.
The second step is positioning scanning, including repeated imaging examinations before treatment. Doctors prefer to use MRI instead of CT because MRI does not produce metal artifactspared to CT. The same is to obtain urate data and eliminate interference.
The third step of dosimetry can be called the patient''s Gamma Knife treatment n. I just introduced the principle of the Gamma Knife, such as where the flying needle of the flying knife should be shot on the tumor, and the intensity density distribution map of the flying needle, all of which require a detailed n from the doctor and input into the machine in advance. The reference is thest positioning film after putting on the patient positioning head frame. Therefore, after the head frame is put onter, the patient needs to enter the MRI room for thest scan positioning.
A group of doctors stood here, exploring the machine program,paring the patient''s previous MRI, and carefully examining whether the treatment can be done properly, lest the patient be unable to repent after putting a head on the head.
Dr. Sun said frankly: "I can''t be 100% sure that I canplete these tumors in one go for her."
It means that the tumor lesions captured by Dr. Song''s superhuman eyes are a bit too small. In the eyes of the radiotherapy doctor, it is hard to say whether these ants-like dots are tumors or not.
On the other hand, some small tumors are located next to important parts of the brain, such as the thmus we mentioned earlier, which is close to the brainstem. Radiotherapy is certainly not a real scalpel, but like a knife killing a tumor, it may identally injure the surrounding or other parts. Therefore, for tumors located in tricky deep ces in the brain, such as neurosurgery, Gamma Knife doctors pay special attention to the cautious area.
If there is no consequence, not only neurosurgery will damage the normal functional area, but it may even stimte the surrounding free cancer cells to make them grow rapidly, resulting in putting the cart before the horse.
Teacher Sun''s concerns are justified.
In view of the current situation of the patient, it may be considered not toplete the treatment at one time, and to wait until the next tumor grows before doing the second time or directly adding the whole brain.
