I will go over the basic interactions between the MRI system and the implantable medical devices focusing on the RF heating.

MRI has three kinds of fields: static field B0, gradient fields, and radiofrequency (RF) fields. Individual field or combined fields can interact with the implanted devices and might cause tissue damage from heating, unwanted nerve stimulation, and image distortion.

Similar to the heart, there is electrical activity in the gastrointestinal tract that is the basis of gastrointestinal contractions. Gastrointestinal electrical stimulation (GIES) is able to modify electrical activity of the gut and therefore altering the functions of smooth muscles of the gut. Depending on stimulation parameters and configurations, GIES may enhance or inhibit gastrointestinal contractions or tone and therefore may have therapeutic potentials for the treatment of gastrointestinal motility disorders and eating disorders, such as obesity.

Boundary integral equations are an efficient approach for the scattering of acoustic and electromagnetic waves from periodic arrays (gratings) of obstacles. The standard way to periodize is to replace the free-space Green's function kernel with its quasi-periodic cousin.
