Medical Physics
Medical Physics (pronounced: med-i-cal phy-sics) is a branch of applied physics that uses physics principles, methods, and techniques in the practice and research of medicine.
Etymology
The term "Medical Physics" is derived from the Greek words "medicus" which means "pertaining to medicine" and "physica" which means "natural science".
Definition
Medical Physics is a field of science that applies the principles of physics to the diagnosis and treatment of human diseases. It involves the use of physics concepts and methods in the creation and implementation of medical technologies and treatments.
