Medical Physics :
Medical Physics is a branch of physics concerned with the application of the concepts and methods of physics to the diagnosis, management, and treatment of human disease. It is allied with medical electronics, bioengineering, and health physics. The main areas of application are treatment of cancer by ionizing radiation ( radiation oncology), imaging with x-rays, ultrasound, and magnetic resonance ( diagnostic radiology), imaging and treatment with radioisotopes ( nuclear medicine), and protection of occupational workers in radiation related industries ( health physics). Other areas of study include electroencephalography, electrocardiography, thermography, hyperthermia, optical imaging, and RF and laser surgery.
