ABSTRACT:
Devices for applying an oscillatory stress to an object positioned in a polarizing magnetic field of an NMR imaging system are used to perform MR elastography. The devices employ electrically energized coils which are connected to drive members and drive plates in a manner to provide various oscillatory forces to an object being imaged. The different oscillatory forces enable different body organs to be imaged using MR elastography methods.
