There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

The acoustic holograms designed by the UPV and CSIC researchers allow for a more controlled opening of the blood brain barrier than which is achieved by exclusively making use of ultrasound.

The system can provide real-time acoustic simulations at the rate of 5 Hz depending on the position of the ultrasound transducer, and succeeded in predicting the position of the ultrasound energy ...

“This is an exciting proof of concept; it’s the first biodegradable transducer made of common and safe medical materials,” says Nguyen. He says the team still needs to work out how to optimize the ...

The researchers found that for transvaginal and transrectal sonographic examinations, the most common method for decontamination of the transducer was barrier protection during the procedure and ...
