[EN] Focused ultrasound has acquired great importance in
the treatment of neurological diseases due to its ability to
generate therapeutic effects in a in precise, non-invasive,
and non-ionizing way. However, focusing ...
[EN] When a surface vibrates compressing the medium on its front, it generates acoustic waves. This is the case of loudspeakers, which generate acoustic waves at audible frequencies by means of a moving surface. In this ...
[EN] Single-element focused ultrasound devices have demonstrated its ability to non-invasively open the Blood Brain Barrier. However, skull irregularities and absorption produce strong aberrations in the ultrasound focus. ...
[EN] Acoustic holograms can encode complex wavefronts to compensate the aberrations of a therapeutical ultrasound beam propagating through heterogeneous tissues such as the skull, and simultaneously, they can generate ...

[EN] Holograms can shape wavefronts to produce arbitrary acoustic images. In this work, we experimentally demonstrate how acoustic holograms can produce controlled thermal patterns in absorbing media at ultrasonic frequencies. ...
[EN] In this work we numerically and experimentally
study the performance of large-volume hyperthermia induced
by acoustic holographic-modulated high-intensity focused ultrasound
(AHmHIFU) in gelatin phantoms. Excellent ...
