Breast vibro-acoustography: initial experience in benign lesions
BACKGROUND Vibro-acoustography (VA) is a newly developed imaging technology that is based on low-frequency vibrations induced in the object by the radiation force of ultrasound. VA is sensitive to the dynamic characteristics of tissue. Here, we evaluate the performance of VA in identifying benign lesions and compare the results to those of mammography. METHODS An integrated mammography-VA sys...
متن کاملQuantitative Measurements in Vibro-acoustography
. Vibro-acoustography (VA) is an acoustic image modality based on the response of tissue under excitation of two ultrasound beams with different-frequencies. The aim of this paper is to provide a quantitative analysis with experimental measurements of the difference-frequency (DF) pressure generated in VA. This analysis considered the radiation force , the induced acoustic emission, and nonline...
متن کاملComb-Push Ultrasound Shear Elastography of Breast Masses: Initial Results Show Promise
PURPOSE OR OBJECTIVE To evaluate the performance of Comb-push Ultrasound Shear Elastography (CUSE) for classification of breast masses. MATERIALS AND METHODS CUSE is an ultrasound-based quantitative two-dimensional shear wave elasticity imaging technique, which utilizes multiple laterally distributed acoustic radiation force (ARF) beams to simultaneously excite the tissue and induce shear wav...
متن کاملApplications of Ultrasound Stimulated Vibro-acoustography
Vibro-acoustography is a method of imaging and measurement that uses ultrasound to produce radiation force to vibrate objects. The radiation force is concentrated laterally by focusing the ultrasound beam. The radiation force is limited in depth by intersecting two beams at different frequencies so that there is interference between the beams at the difference frequency only at their intersecti...
متن کاملVibro-acoustography and multifrequency image compounding.
Vibro-acoustography is an ultrasound based imaging modality that can visualize normal and abnormal soft tissue through mapping the acoustic response of the object to a harmonic radiation force at frequency Δf induced by focused ultrasound. In this method, the ultrasound energy is converted from high ultrasound frequencies to a low acoustic frequency (acoustic emission) that is often two orders ...
