Applications of Medical Physics: Radiation Therapy, Nuclear Medicine
Medical physics is the application of physics to medicine. It plays a very important role in
diagnosing and treating diseases, especially in the fields of radiation therapy and nuclear
medicine.
1. Radiation Therapy: This is a type of cancer treatment that uses high doses of radiation to kill
cancer cells or shrink tumors. Radiation can destroy the DNA inside the cancer cells, which
stops them from growing and multiplying. Special machines like linear accelerators are used to
deliver this radiation to specific parts of the body without damaging the surrounding healthy
tissue.
Example: A patient with a brain tumor may receive radi...
