Medical physics is a branch of applied physics using concepts and methods of physics to help diagnose and treat human disease. The fusion of medicine, physics, technology, and basic sciences makes Medical Physics one of the most fascinating sub-specialties of physical sciences A medical physicist is an expert in radiation physics. He practices medical physics, interacts directly with the radiation oncology team, and is responsible for radiation treatment planning. The medical physicist guarantees the accurate measurements of the radiation beam. His goal is to compute the correct radiation dose that can best destroy malignant tumors while minimizing damage to normal tissue. In addition, he also plays a major role in the radiation protection, safety, and functioning of radiotherapy units, radiation sources, and radiation detection equipment Employment for a Medical Physicist is wide and possible in institutions such as hospitals, cancer centers, nuclear power plants, radiopharmaceutical production facilities and the academia and foreign opportunities are many. The foremost pathway to becoming a medical physicist requires a postgraduate degree such as a master’s (MSc) or a doctorate (Ph.D.) in medical physics. In addition, clinical practice under the supervision of a Medical Physicist is also required. Want to know more about medical physics?
