Polar coordinate coherent passive acoustic beamforming for the modifiable improvement of image quality and field of view

Passive acoustic mapping (PAM) has been implemented for cavitation localization, quantification and detection in therapeutic ultrasound research. Having both imaging and therapy transducers coaxial would help move this purely laboratory technique close towards clinical use. In this study, a phased-array transducer was co-aligned in the middle of a single element HIFU transducer. Due to the limited...
