What is Medical Physics?

Medical physics involves the application of physics concepts, theories, and methods to medicine and healthcare. It plays a crucial role in the diagnosis and treatment of diseases.

Non-Ionising Instrumentation Techniques

These techniques use non-ionising radiation, such as ultrasound and magnetic resonance imaging (MRI), to visualize and diagnose medical conditions without causing ionization of atoms.

Ionising Instrumentation Techniques

Ionising radiation-based techniques, like X-rays and computed tomography (CT), are used to create detailed images of the internal structures of the body.
