ABSTRACT:
Devices for producing an oscillatory shear stress within an object positioned in a polarizing magnetic field of an NMR imaging system are used to perform MR elastography. In one embodiment shear stress is produced within the brain by vibrating the entire skull with a transducer that is gripped by the patient's teeth.
