Magneto-Acoustic Technology
MRI imaging is expensive and carries some risk of tissue damage from the radiation it relies upon. Engineers at Stanford have been developing magneto-acoustic imaging as an alternative. “In MA imaging, the tissue is placed in a constant, roughly uniform magnetic field. Lower frequency RF currents are introduced in the tissue, roughly perpendicular to the magnetic field. The currents and field interact to produce oscillatory Lorentz forces in the tissues. Ultrasound waves are then generated at tissue conductivity boundaries and can be detected at millimeter resolution.” MORE
