The electrons are accelerated to a speed close to the light along with an evacuated tube and in order to generate an X-ray beam, the electrons are being deflected as a general rule to 90o via electromagnets to hit the target. The electrons quickly reduce their speed, giving up their energies to high-energy X-radiation because the electron energies involved are so greater compared to X-ray tube. A transmission target is used whereby X-rays are being produced from the long side of the target and directed into the patient. A computer-controlled gantry and treatment couch ensure any treatment position, whereas a dose monitor is used to measure the cumulative dose and to cut off the device at the appropriate …show more content…
During the treatment, a machine is used to place the radioactive material inside the applicator and once the treatment is over the machine takes back radioactive material and the applicators is removed. The brachytherapy could be given into two different treatments(high or low dose rate treatment). With the bothtreatments a same dose of radiotherapy is given, whereas for over a different time. High dose rate treatment is given for a short period of time, whereas low dose are given for longer period of time.
Small radioactive seeds of Iodine-125 could be inserted where the tumor is located and they are left inside to release their radioactivity slowly. This process sometimes is known as low-dose rate treatment. The seeds are not removed from the patient and eventually fades away for the time of six months. All of the radioactivity is absorbed by the prostate so therefore it's safe for the patient to stay next to other
