Abstract: An ultrasound transducer may include: a plurality of capacitive ultrasound transducer elements; and a base having a largest dimension sized and shaped to be disposed with an external ear canal, wherein the plurality of capacitive ultrasound transducers is mounted on the base. Each capacitive ultrasound transducer element and the ultrasound transducer are specifically constructed to achieve select desired performance characteristics. The ultrasound transducer may have an angular beam spread through a gaseous medium of greater than 15 degrees and an attenuation loss through the gaseous medium of greater than 10 dB measured at a distance 12.5 mm to 25 mm along a primary transmission axis of the ultrasound transducer. The ultrasound transducer may be particularly useful for characterizing fluid behind an ear drum to diagnose otitis media.

Abstract: Ultrasound transducer element arrays using acoustic ensonification drive patterns via a patient interface for sonosensitizer activation in sonodynamic therapy. Incoherent acoustic field generation varying phase, frequencies, and/or amplitude via controlled delivery of low intensity planar acoustic waves. Method includes generating a first and a second signal to generate respective acoustic ensonification drive patterns with phase, frequency, and amplitude and generating at least one relative phase, frequency or amplitude difference to generate a third incoherent acoustic ensonification pattern to activate a sonosensitizer. Calibration and complementary therapy procedures to improve cell susceptibility of cells to sonodynamic therapy are disclosed.

Abstract: A non-Hermitian complementary metamaterial (NHCMM). Acoustic transmission systems including an acoustic wave generator configured to generate an acoustic wave and propagate the acoustic wave through a tissue of a specimen, and the NHCMM, which is configured to add a first amount of energy amplification coherently to the acoustic wave to account for energy loss in the acoustic wave as a result of the wave propagating through the tissue of the specimen. The acoustic wave generator can be an ultrasound generator, and the tissue can be a cranium.
