The purpose of this research was to develop a novel mechanical wave driver device for Magnetic Resonance Elastography of the Breast. The design goal was to develop a driver can be used with any breast RF coil, including multichannel designs. The driver is entirely passiv, non-metallic, and consists of an array of elastic tubes Experimental testing with a breast phantom demonstrates that the driver provides uniform shear wave illumination, and other favorable characteristics, making it an attractive alternative to a special combined driver/RF coil for breast MRE.
