Vibro-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 ...
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 کاملApplication of image restoration algorithms in vibro-acoustography images
Vibro-acoustography (VA) is an imaging modality that produces an image of the mechanical response of an object to a localized dynamic radiation force of an ultrasound field. This technique has been studied and used in clinical applications as to image calcification in breast tissue and arteries. This paper presents the application of restoration algorithms to VA images.
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 کاملIntegration of Vibro-Acoustography Imaging Modality with the Traditional Mammography
Vibro-acoustography (VA) is a new imaging modality that has been applied to both medical and industrial imaging. Integrating unique diagnostic information of VA with other medical imaging is one of our research interests. In this work, we establish correspondence between the VA images and traditional X-ray mammogram by adopting a flexible control-point selection technique for image registration...
