Wide bandwidth for an air-coupled piezoelectric micromachined transducer (PMUT) is important to achieve short pulse transmission and reception in pulse-echo imaging with high axial resolution. Here, ...

Multifunctional Injectable Microspheres Containing “Naturally-Derived” Photothermal Transducer for Synergistic Physical and Chemical Treating of Acute Osteomyelitis through Sequential Immunomodulation ...

The influence of the transducer lens on image reconstruction is often overlooked. Lenses usually exhibit a lower sound speed than soft biological tissues. In academic research, the exact lens sound ...
