Abstract

Vibro-acoustography is an imaging method based on the vibro-acoustic response of the object to a low-frequency radiation force of ultrasound. Here, we present the results of a study on detection mass lesions by vibroacoustography. Experiments were conducted on excised human liver tissues that included focal mass lesions which were a few mm to a few cm in diameter. The 3 MHz transducer used for this purpose provided a 0.7 mm lateral resolution. The focal length of the transducer was long enough to cover the entire 5 mm thickness of the specimen. Several scans of each sample were obtained. Resulting images distinctively showed the normal liver tissue and the mass lesions. Masses appeared with enhanced boundary and rough textures in VA which allowed us to delineate the masses from the surrounded tissue. These results suggest that vibro-acoustography may be a clinically useful imaging modality for detection of mass lesions in soft tissue.
