title: Excite and receive solenoid radiofrequency coil for MRI-guided breast interventions.
abstract: A radiofrequency coil based on a solenoid design was developed and integrated with a novel device for MR-guided breast interventions using a circumferential approach. The transmit/receive tapered solenoid design conforms to the shape of the pendent breast, and provides open circumferential needle access to breast tissue under rotational symmetry. Phantom and in vivo studies using a healthy volunteer demonstrated a superior uniformity using the tapered solenoid coil compared with a commercial 8-channel diagnostic imaging coil. The solenoid coil design has important advantages due to localized transmit/receive such as B(1) -homogeneity and reduced specific absorption ratio (SAR) especially at high-field strengths. Because it provides open access and a rotationally symmetric local field, the tapered solenoid design can easily be adapted for bilateral imaging and 3D MR-guided breast interventions.
