Gradient‐induced vibrations and motion‐induced Lenz effects on conductive nonmagnetic orthopedic implants in MRI

Purpose To quantify the extent of gradient‐induced vibrations, and the magnitude of motion‐induced displacement forces (“Lenz effect”), in conductive nonmagnetic orthopedic prostheses. Methods The investigation is carried out through numerical simulations, for a 3 T scanner. For gradient‐induced tor...
