Chapter 3547 [3547] Various considerations

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

    Just like what is written in science fiction novels, the cool thing about technology is that rows of complex digital chart control images are floating around on the screen, just like mathematical souls flying.

    ¡°The operation interface seems very complicated.¡± Dr. Ou Feng stood at the back and took a glance at it and said.

    If you haven¡¯t learned it before, the first time you see it it¡¯s like reading a book from heaven.

    The more intelligent the machine, the more accurate the calculated results must be, and the prerequisite must be more accurate in input data.

    How to achieve the accuracy of input data, refer to the previous membrane lung verification link. It is best to eliminate interference in the way of obtaining each number, 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 his or her hair.  In fact, you can use Gamma Knife without shaving your hair. Long hair is best cut short.  The obvious advantage of shaving your hair and cutting it short is that it can eliminate interference and help doctors and machines work more accurately.

    Precise positioning.  Considering that this patient has seven tumors in his brain, and the latest machines are used to treat them.  Anyway, hair loss may occur after radiotherapy. The patient¡¯s appeal must be that it is best to eliminate the tumor at once, and simply shave his hair for the best results.

    Precise positioning is better.

    Don¡¯t worry about shaving your hair, your hair will grow back soon.  What we are most afraid of clinically is the things that cannot grow back, such as hair loss and baldness, which may not be cured.  The second step is the positioning scan, which includes repeated imaging tests before treatment. Doctors prefer to use magnetic resonance instead of CT because magnetic resonance does not produce metal artifacts compared to CT.  The same is to obtain accurate data arrangement

    Get rid of distractions.  The third step of dosimetry can be called the patient¡¯s Gamma Knife treatment plan.  We have just introduced the principle of 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. These all require the doctor's detailed plan and input into the machine in advance.  The reference is the last positioning radiograph after the patient is positioned on the head frame.  Therefore, after the head frame is put on later, the patient needs to enter the MRI room for the last scan and positioning

    A group of doctors stood here, fumbling with the machine's program, comparing it with the patient's previous magnetic resonance imaging, and carefully examining whether the treatment could be done properly, lest the patient be put on a headband and unable to repent.

    Dr. Sun said honestly: "I can't guarantee 100% that I can treat her tumors in one go."

    ¡°It means that the tumor lesions caught by Dr. Song¡¯s superhuman eyes are a little too small. In the eyes of the radiotherapy doctor, it is difficult to say whether these small ant-like dots are tumors.  On the other hand, some small tumors are located close to important parts of the brain, such as the thalamus we talked about before, which is close to the brainstem.  Although radiotherapy is not a real scalpel, it is similar to a knife that kills tumors, and there is a fear of accidental injury.

    Around or other parts, so for tumors located in difficult and deep locations in the brain, such as neurosurgery, Gamma Knife doctors are particularly cautious about areas.

    There are consequences for not killing the patient properly. Not only will it damage normal functional areas like neurosurgery, but it may even stimulate the surrounding free cancer cells to cause them to grow rapidly and put the cart before the horse.

    Teacher Sun¡¯s concerns are justified.  In view of the patient's current condition, it may be possible to consider not completing the procedure at one time, but wait until the tumor grows larger before undergoing a second procedure or directly adding whole-brain radiotherapy.  (Remember the website address: www.hlnovel.com
