Ultrasonic transducer device and method |
| abstract |
An ultrasonic transducer may include: a plurality of capacitive ultrasonic transducer elements; and a base having a maximum size, the size and shape of which is adjusted to be disposed within the external auditory canal, wherein the plurality of capacitive ultrasonic transducers are mounted on the pedestal. Each capacitive ultrasonic transducer element and ultrasonic transducer is specially constructed to achieve selected desired performance characteristics. The ultrasound transducer may have an angular beam propagating through the gaseous medium greater than 15 degrees and an attenuation loss through the gaseous medium of greater than 10 dB measured at distances of 12.5mm to 25mm along the main transmission axis of the ultrasound transducer. Ultrasound transducers may be particularly useful for characterizing the fluid behind the ear drum to diagnose otitis media. |
