Focal volume, steering, and aberration correction in transcranial focused ultrasound: reconsidering the tradeoffs between single-element transducers, phased arrays, and acoustic holograms [PDF]
Frontiers in NeuroscienceTransducer architecture is an increasingly important design consideration in transcranial focused ultrasound, where focal precision, electronic steering, skull-aberration correction, workflow complexity, and cost must be balanced. Under matched aperture,

Investigating the thermal stability of 1-3 piezoelectric composite transducers by varying the thermal conductivity and glass transition temperature of the polymeric filler material [PDF]
, 2002 The thermal behaviour of a number of 1-3 piezoelectric composite transducers is discussed. In particular, devices manufactured from a polymer filler with a relatively high glass to rubber transition temperature (T-g), and from polymer systems with ...
