A 3 MHz ultrasound transducer transmits a 3-cycle long pulse into a soft tissue at normal incidence to fat and liver interface. The axial resolution (mm) and the amplitude reflection coefficient at fat-liver interface, respectively, are _______.
Use Ctissue = 1500 m/s, Cfat = 1450 m/s, Cliver = 1570 m/s, ρfat = 920 kg/m³, ρliver = 1060 kg/m³
Use Ctissue = 1500 m/s, Cfat = 1450 m/s, Cliver = 1570 m/s, ρfat = 920 kg/m³, ρliver = 1060 kg/m³
Correct : d
