Low E-Field and Low Acoustic Birdcage Coil Design

Saikat Saha¹

This abstract presents a novel design of a low E-field and low acoustic Birdcage type of coil. In this coil, wider rungs with cutouts and or slits have been implemented at the highest eddy current (from the gradient coil interaction) locations to minimize the acoustic vibrations. The wide nature of the rungs reduces the patient loss and hence the SAR and the strategic placement of the cutouts control the bore noise to a great extent.
