Great progress has been made recently in high frequency ultrasound imaging. In particular, several works have shown the interest of echographic exploration for frequencies ranging from 20 to 100 MHz, in dermatology and ophthalmology. These results are extending the field cf application of tissue characterization. The measurement of acoustic attenuation tissues has received much interest in the field of ultrasound tissue characterization. Indeed, several clinical applications have shown a correlation between attenuation values and pathological states.
