Medical physics

Medical physics is a special kind of science that helps doctors use machines and other tools to diagnose and treat problems in our bodies.

Doctors use different types of equipment and machines to look inside our body and find any kind of problems like a broken bone or a tumor. They use X-rays, CAT scans, MRI (magnetic resonance imaging) and other types of machines.

Medical physicists help to make sure these machines are working properly and safely. They use physics to understand how these machines work and what kind of effects they can have on our body. They also help doctors in selecting the best machine and techniques for a specific type of problem.

Medical physicists also help with radiation therapy, which is when doctors use radiation to treat cancer. They make sure that the radiation is being given safely so that it only affects the area that needs treatment and doesn't harm healthy areas of the body.

In summary, Medical physics is a science that helps doctors make sure they are using machines and other tools safely and effectively to diagnose and treat problems in our bodies.
