Course Description
This course is designed to provide a theoretical and practical guide to RF coil design for both animal and human systems. Simple tools for electrical circuit analysis will be introduced, followed by practical design of simple geometries such as surface coils. The participants will then design and construct a coil with their chosen dimensions and frequency of operation. In the second stage, the design of volume coils will be introduced from a theoretical basis, software for modelling these coils discussed, and again the participants can choose which type of coil to design during the practical session. Finally, advanced topics such as multi-tuned coils and phased arrays will be introduced, designed and tested.
In addition to the large degree of practical work, the course will also include a substantial amount of time that will be spent on exercises, which are intended to enhance the understanding of basic and advanced topics and will be performed in small participant groups under guidance of the lecturers.
Since participants will construct their own coil, this course is limited to maximal 20 participants.
