Temperature Simulations for MRI

Simulations of Temperature for MRI

In Magnetic Resonance Imaging (MRI) a variety of magnetic fields are applied to the human body to manipulate the hydrogen nuclei throughout the body. These fields interact with the body in a variety of ways, producing both the desired signal and favorable image contrast, but also side effects including image distortions and heating of tissues.

We develop a variety of numerical methods and tools considering anatomical models of the human body in the MRI environment and use them to characterize electromagnetic field behavior, image appearance, and temperature increase due to field/tissue interactions in MRI. Such tools are increasingly becoming an integral part of engineering and safety assurance in MRI.

Temperature

In order to predict the real implications of RF-induced heating (SAR) in MRI, we have implemented a bioheat equation in some three-dimensional models of the human head and forearm 1-4. Our methods have allowed us to compare experimental and simulated results in vivo 1 and also make some predictions of Temperature changes due to physiological activity 5.
