In this one-day course, the principles of RF coils used to detect and excite the MR signals will be discussed, beginning with the transmission lines that interconnect the coils to the MR system, and extending to single surface and volume coils and finally RF coil arrays for both transmit and receive. A discussion of the RF modeling tools used to analyze these coils and coil arrays, and their interaction with the patient and the environment will lead into the interaction of RF fields with other devices that may be found in the MR environment, including such devices as implantable devices and EEG leads. The course will conclude with a live demonstration (or by video and live commentary) of the construction and tuning of RF coils for humans and animals.
Upon completion of this course participants should be able to:
Describe the basic theory, design and construction of single and multi-tuned RF coils and their feed networks;
Explain the principles of operation and basic applications of receive and transmit RF coil arrays;
Describe the major methods of RF modeling commonly in use and the relative advantages and disadvantages of each; and
Discuss the interaction of the RF signals used for MRI with other devices that may be used in the MR environment, such as implantable devices, EEG and EEG devices, PET detectors and NIR sensors.
This course is designed for MR technicians, scientists and engineers with an interest in understanding physical principles behind MR safety issues related to RF fields, and/or the construction, design or use of RF coils and RF coil arrays.
