Acoustic Holograms for Bilateral Blood-Brain Barrier Opening in a Mouse Model

Jiménez-Gambín, Sergio; Jimenez, Noe; Pouliopoulos, Antonios N.; Benlloch Baviera, Jose María; Konofagou, Elisa E.; Camarena Femenia, Francisco (Institute of Electrical and Electronics Engineers, 2022-04)

[EN] Transcranial focused ultrasound (FUS) in conjunction with circulating microbubbles injection is the sole non-invasive technique that temporally and locally opens the blood-brain barrier (BBB), allowing targeted drug ...
Acoustic Holograms for Hyperthermia and Transcranial Ultrasound

Andrés Bautista, Diana (Universitat Politècnica de València, 2024-07-04)

[ES] Los ultrasonidos se han empleado desde los años 90 para el tratamiento de múltiples patologías gracias a su carácter no invasivo y no ionizante, desde el tratamiento localizado del cáncer hasta terapias neurológicas. ...
Generating Bessel beams with broad depth-of-field by using phase-only acoustic holograms

Jiménez-Gambín, Sergio; Jimenez, Noe; Benlloch Baviera, Jose María; Camarena Femenia, Francisco (Nature Publishing Group, 2019-12-27)

[EN] We report zero-th and high-order acoustic Bessel beams with broad depth-of-field generated using acoustic holograms. While the transverse field distribution of Bessel beams generated using traditional passive methods ...
Holographic Focused Ultrasound Hyperthermia System for Uniform Simultaneous Thermal Exposure of Multiple Tumor Spheroids

Andrés, Diana; Rivens, Ian; Mouratidis, Petros; Jimenez, Noe; Camarena Femenia, Francisco; Ter Haar, Gail (MDPI AG, 2023-04-28)

[EN] Hyperthermia is currently used to treat cancer due to its ability to radio- and chemo-sensitize and to stimulate the immune response. While ultrasound is non-ionizing and can induce hyperthermia deep within the body ...
Multifocal acoustic holograms for deep-brain neuromodulation and BBB opening

Andrés, Diana; Jiménez-Gambín, Sergio; Jimenez, Noe; Camarena Femenia, Francisco (IEEE, 2020-09-11)

[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. ...
Numerical Study of Acoustic Holograms for Deep-Brain Targeting through the Temporal Bone Window

Andrés, Diana; Jimenez, Noe; Benlloch Baviera, Jose María; Camarena Femenia, Francisco (Elsevier, 2022-05)

[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 ...
Ultrasonic Holograms to Enhance Hyperthermia Volumes

Andrés, Diana; Vappou, Jonathan; Jimenez, Noe; Camarena Femenia, Francisco (IEEE, 2021-09-16)

[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 ...
