Antenna Effect In Mri at Melva Spruell blog

Antenna Effect In Mri. The basic principles, proper selection and use, problems and image artifacts, and quality assurance of rf coils used in clinical mri are discussed to serve as a guide to optimize image quality, prevent image artifacts, and reduce rf heating risk. An intuitive explanation for the antenna effect is that an incident field of appropriate wavelength and oriented along the. It has been demonstrated that objects made of conductive material that have an elongated shape, for example lead wires, catheters and electrodes, and are of a specific length that causes resonance with the rf field have a high risk of heating. Wires and elongated conductive objects can act like antennas, capturing electromagnetic waves to extract power from them. Two primary heating mechanisms, electromagnetic induction and the antenna effect, are possible. 2, 13 known as the antenna effect, the potential current induced in such objects when. In this study, mri‐induced heating.
