Everyone filed into the control room and gathered in front of the machine screen.
As written in a science fiction , the coolest thing about technology is that rows of complex digital graphics control screens float around on the screen, as if the mathematical soul is flying.
"The operation interface seems to be very complicated." Dr. Ou Feng stood behind, took a glance at it on tiptoe and said.
Follow on NovᴇlEnglish.nᴇtI 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 accurate the calculated results must be, and the premise must be more accurate in the input data.
How to ensure the accuracy 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 the latest 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 accurate 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 artifacts compared to CT. The same is to obtain accurate data and eliminate interference.
The third step of dosimetry can be called the patient's Gamma Knife treatment plan. 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 plan from the doctor and input into the machine in advance. The reference is the last positioning film after putting on the patient positioning head frame. Therefore, after the head frame is put on later, the patient needs to enter the MRI room for the last scan positioning.historical
A group of doctors stood here, exploring the machine program, comparing 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 can complete these tumors in one go for her."
Follow on Novᴇl-Onlinᴇ.cᴏmIt 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 thalamus 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 accidentally injure the surrounding or other parts. Therefore, for tumors located in tricky deep places 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 stimulate 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 to complete the treatment at one time, and to wait until the next tumor grows before doing the second time or directly adding the whole brain.
