Combined 3D Electromagnetic and Spin Response Simulation of MRI Systems

Modern MRI systems are highly complex devices, and the interaction between the body and MRI coils introduces additional challenges into the design process. The body, with its complicated heterogeneous interior, causes major disturbance to the homogeneity of the magnetic fields, while energy absorbed by the body can cause harmful heating. Experimental measurement of these effects is often impossible, but simulation with 3D body models can help the engineer identify risks to the patient and suggest ways to reduce them.
