Abstract

Some of the major problems in magnetic resonance imaging are related to static artifacts generated through interactions with the main magnetic field. The artifacts caused by biomedical implants such as orthopedic braces, prostheses or other fixation device implants distort the information contained in the image and impair the process of clinical investigation. In this paper we present preliminary results of a non-linear adjustive method for partial reduction of such type of distortion.
