 Hi, Myself Dr. Ramakrishna, in this video, we will try to find out how the medicines are related to radiation in this video. This radiation treatment is used to cure many patients. In some patients, we also find out that radiation is very helpful. Coming to techniques of radiation treatment. We will try to answer the questions that are related to radiation in this video. In this cancer, if we look at the techniques once, we can see that we have two-dimensional, three-dimensional radiotherapy, IMRT, IGRT, V-MAT, stereotactic radiotherapy, or stereotactic body radiotherapy. In this, we can divide it into groups. In this method, if we look at it once, this 2D technique is present, outdated. Before this, a treatment of 30-40 years has taken place in these 2D methods. Due to this, there is not a lot of radiation due to the lack of oxygen. There is a lot of side effects. Before this, if you look at it, the part of the patient that has been done has gone bad, the part of the patient that has lost all his weight, and to see it a little bit, there are some patients who have some problems. Due to this 2D technique, due to the lack of treatment that cannot be done precisely, patients have all these problems. So, due to these patients, there are many patients who have this radiation treatment, if they do not have it, there are many other problems. But due to the lack of time, there are so many new methods for us. So, due to this 2D technique, the three-dimensional conformal radiotherapy is present. Otherwise, it is called IMRT. It is called V-MAT. It is called image-guided radiotherapy. And in some tumours, in some facilities, we use this radiotherapy only. So, broadly, we can think of it in two ways. One is simple therapy. Two is advanced. We have open surgery, laparoscopic, and robotic surgery. In radiation too, we have simple radiation techniques called advanced radiation techniques. We have these techniques. These simple radiation techniques are called 3DCRT. And in advanced radiation, we have this IMRT, V-MAT, IGRT, this radiotherapy, these methods are called 3DCRT. So, what is 3DCRT? What is 3DCRT? If we look at it once, it is called 3-dimensional conformal radiation. So, we can think of it as 3DCRT for some cancer. So, to briefly explain this, if we think of it as cancer, we can think of it as normal structures, critical structures too. So, in terms of 3DCRT, in terms of 3DCRT, we do not have this tumor alone. These surrounding areas also have some dosa. It goes for some time. So, in these structures, the structure here can be very sensitive. It can be very sensitive. It can be moderately affected by radiation. It can be affected by the actual effect. So, in these situations, it is not a problem. But, there is a very sensitive radio structure here. It can also be used as a dosa for this tumor. So, it is a function that can be used. So, because of this, it can be affected by our patient. Similarly, due to radiation in our body, there is some tolerance. It can be limited due to radiation. So, some organs can be affected. Some organs can be affected. So, due to these IMRT structures, if we are here for cancer, only this part needs radiation dosa. For other parts of the body, we can choose this radiation dosa. So, when it comes to advanced techniques, mainly IMRT V-MAT IGRT So, it is also called rapid arc. In IMRT structures, in V-MAT structures, mainly, we need to treat it in a precise way. For other parts of the body, for healthy tissues, we need very less radiation dosa. This happens only. For other parts of the body, in advanced techniques, we call it inverse technique. It is a command for our computer. So, if we give a command that a limit dosa should not go, we will generate a treatment planning system. If we do not have acceptable levels, we will see oncologists, for the parts we want, within limits, for radiation dosa, and if we see more cancer, we will get more dosa in these areas. So, for cancer, we will get more dosa. For other parts of the body, we will get less dosa. We will get treatment. Due to this, patients will get more dosa. So, in these areas, if we look at the difference, in IMRT, generally, we will get treatment from 12 to 15 minutes. We will get treatment from 2 to 3 minutes. So, in IMRT, in advanced, advanced, so, for this image-guided radiotherapy, the main difference is for this IMRT, for VMAID, we will get treatment 1 minute before, we will get X-ray and in the patient's correct position, we will get treatment if it is not in the correct position, we will get X-ray or 2-dimensional verification. So, by doing this, we can correctly deliver the treatment or we can decide. In the same image-guidance techniques, we can scan a CT and in 3-dimensional verification, in the patient's correct position, we can plan the treatment or we can in the IGRT technique, we can verify it in 3-dimensional and adjust it if it is not in the correct position, we can get treatment. So, even if it is not in the correct position, even if it is not in the correct position, we can miss the target. So, this image-guidance technique is a very precise treatment. In the IMRT, with this image-guidance, we can get treatment. We can also get treatment with this image-guidance. So, in this way, we can get treatment smoothly. Because of that, patients have less problems. We can finish the treatment in a short time. Then, the patient recovery time is much better. And, we can get treatment with this image-guidance. We can get treatment with this image-guidance. We can get treatment with this image-guidance.
