Medical radiation therapy tungsten needles usually refer to a special type of tungsten needle used in tumor treatment. These tungsten needles are designed to carry radioactive isotopes, which are used to deliver radiation therapy by introducing the radioactive isotopes into the tissue that has the tumor.
Here are some relevant features and applications:
1. Material characteristics: Radiation therapy tungsten needles are usually made of tungsten or tungsten alloy. Tungsten has a high density and high atomic number, which makes it ideal for carrying radioactive isotopes.
2. Isotope carrying: A radioactive isotope, such as tungsten-188, may be attached to or injected into the tungsten needle, allowing the needle to treat tumor tissue through its radioactivity.
3. High precision: These tungsten needles usually need to be manufactured very precisely to ensure that the radioactive isotope can be accurately released into the target tissue during treatment, minimizing damage to surrounding healthy tissue.
4. Minimally invasive surgery: Medical radiation therapy tungsten needles may be designed as minimally invasive surgical tools that can be guided to the target area through small incisions or catheters.
5. Tumor treatment: The main application of these tungsten needles is in tumor treatment. By introducing radioactive isotopes into tumor tissue, tumor cells can be reduced or killed to achieve therapeutic purposes.
The specific design and use of tungsten needles for medical radiation therapy may vary depending on the treatment method, tumor type and patient condition. Treatment planning and application must be determined by a medical professional.
