　Abstract
　Magnetic Resonance Imaging (MRI) scanners are an important diagnostic
　tool for the medical practitioner. MRI provides a non-invasive means
　of imaging soft tissues and to obtain real-time images of the cardiovascular
　system and other dynamic changes in the human body. MRI scanners rely
　heavily on a number of topical areas of interest to Electrical Engineers:
　image processing, high speed computing and RF (radio frequency) systems
　and components. This presentation will focus on some of the RF aspects
　of the MR process and MR scanners. A primer on the physical phenomenon
　behind magnetic resonance will start the presentation and include a
　discussion of the origin of the MR signal. The need for the high static
　magnetic field (B0), the use of gradient coils for MR signal location,
　simple RF pulse sequences and how they are used in image construction
　will be covered. This MR image construction process and the control
　of the various steps that manipulate the atomic nuclei to generate the
　final MR diagnostic image put demanding constraints on RF equipment
　capabilities and these will be discussed, along with a high-level overview
　of the various components making up conventional MRI systems.
　This high-level overview will include a look at various examples of
　transmit and receive RF systems and examples of transmit and receive
　coils that make up MR scanners and system diagrams for both the
　RF transmit and receive paths. The talk with then narrow in scope
　to look at how these RF coils are modeled and controlled in both
　transmit and receive states and how these components are used
　for transmit/receive switching and patient and equipment protection.
