Abstract
The heating of orthopedic implants under MRI RF fields were investigated 1.5T and 3T systems. Modeling and experiments were performed on an orthopedic device at different sizes inside an ASTM phantom. It is observed that the induced energy deposition near the device is almost linearly related to the dimension of the orthopedic implants when the device is less than 10 cm in length. Higher temperature rises were found in 1.5T for both computational and experimental studies.
