Douglas-Gunn method applied to dosimetric assessment in magnetic resonance imaging

This work analyses the thermal effects produced by the time-varying magnetic fields of a Magnetic Resonance Imaging scanner in the patient’s body, also considering the case of a metallic implant. The computations are performed by the successive solution of an electromagnetic field and a thermal problem. In particular, the performances of a transient thermal solver, implemented according to the Douglas-Gunn scheme, are discussed and compared with other computational procedures. An example of application is finally presented.
