PPT-Introduction to Magnetic Resonance

David J Keeble Magnetic Resonance Magnetic moments Magnetic What matters is matter with moments Matter Leptons and quarks The simplest fundamental particle is the lepton the electron. In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir Microwave Engineering .

Definition: when a force is applied to an object in repeated motion at exactly the natural frequency, an increase in amplitude occurs.. Important points: force applied AT the natural frequency!.

MRI(Magnetic Resonance Imaging). Radiation Safety (SEC). SUBJECT CODE – PHYS307TH. Magnetic Resonance Imaging (MRI). It is not possible to see the internal organs and structure of the human body directly to locate the infection or illness . Magnetic resonance imaging (MRI) is a spectroscopic imaging technique used in medical setting to produce image of the internal structure of the human body. The scan uses a strong magnetic field and radio waves to generate images of internal parts ( cells, tissues , organs ) of the body that can't be seen as well with X-rays , CT scans or ultrasounds . For example , it can help doctors to see inside joints , cartilage , ligaments , muscles and tendons , which make it helpful for detecting various sports injuries. It is also used to examine internal body structures and diagnose a variety of disorders , such as strokes, tumors , aneurysms , spinal cord injuries , multiple sclerosis and eye or inner ear problems. It is also widely used in research to measure brain structure and their function.. LL8 section 79. Permittivity . e. (. w. ) approaches unity at UV frequencies.. Permeability . m.
