NON INVASIVE ASSESSMENT OF LIVER FAT BY CRAWLING WAVE DISPERSION

摘要

Using a modified ultrasound device crawling waves are applied to the liver over a range of shear wave frequencies. Dispersion measurements are obtained that reflect tissue viscosity and these correlate with the degree of steatosis. A device for the process has an actuator on either side of the ultrasound transducer to apply shear waves which interfere to produce the crawling waves.
