Chapter 3547 【3547】Various Considerations

Everyone filed into the control room and gathered in front of the machine screen.

As written in science fiction, the coolest thing about technology lies in the fact that rows of complex digital graphics control screens float around on the screen, as if the soul of mathematics, physics and chemistry is flying.

"The operation interface seems to be very complicated." Dr. Ou Feng stood behind, took a glance at it on tiptoe and said.

It feels like if you 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 shaves 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 there are as many as seven tumors in this patient's brain, and the latest machine is used to treat it. 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.

If you shave your hair, it will grow back in no time. 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.

A group of doctors stood here, groping for the machine program, and comparing it with the patient's previous MRI, and then carefully examining whether the treatment can be done properly, so as not to give the patient a headache and then be unable to repent.

Dr. Sun said truthfully: "I can't be 100% sure that I can treat all these tumors for her in one go."

It means that the tumor lesions caught 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 small ants-like dots are tumors.

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 are no consequences, it will not only damage the normal functional areas like neurosurgery, but may even stimulate the surrounding free cancer cells to make them grow rapidly, causing the consequences of 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, but to wait until the next tumor grows and then do the second treatment or directly add whole-brain radiotherapy.
