Development of an Estimation Instrument of Acoustic Lens Properties for Medical Ultrasound Transducers

Figure 7

Measurement results of the (a) velocity and (b) attenuation coefficient. Acoustic lens 1, 2, 3, and 4 represent the calculated attenuation coefficient of the receiving ultrasound signal four times (acoustic lens 1, 2, 3, and 4 are represented by red solid, green dashed, purple solid, and blue dashed-dot lines, resp.).
