An Active Dynamic Vibration Absorber for a Hand-Held Vibro-Elastography Probe

  title={An Active Dynamic Vibration Absorber for a Hand-Held Vibro-Elastography Probe},
  author={Robert Rohling},
Vibro-elastography is a new medical imaging method that identifies the mechanical properties of tissue by measuring tissue motion in response to a multi-frequency external vibration source. Previous research on vibro-elastography used ultrasound to measure the tissue motion and system identification techniques to identify the tissue properties. This paper describes a hand-held probe with a combined vibration source and ultrasound transducer to implement the new method as a practical device. The… CONTINUE READING
