A 32 element receiver array was designed and integrated into an existing 1372 element transcranial therapy array to introduce real-time treatment monitoring capabilities. A semi-randomized array layout allowed signals from a narrowband source to be detected and localized within the array field of view. The combined array was used to sonicate microbubbles and detect their emissions both directly and...
A hemispherical-focused, ultrasound phased array was designed and fabricated using 1372 cylindrical piezoelectric transducers that utilize lateral coupling for noninvasive transcranial therapy. The cylindrical transducers allowed the electrical impedance to be reduced by at least an order of magnitude, such that effective operation could be achieved without electronic matching circuits. In addition,...
