Ardalan Kahak, Moustafa Sayed Ahmed, Nahid Kalantaryardebily +4
Morphing surfaces provide a versatile tool to advance the functionalities of high-performance aircraft, soft robots, biomedical devices, and human-machine interfaces. However, achi…
A Roadmap to Holographic Focused Ultrasound Approaches to Generate Thermal Patterns
Ceren Cengiz, Zekeriya Ender Eger, Pinar Acar +2
In therapeutic focused ultrasound (FUS), such as thermal ablation and hyperthermia, effective acousto-thermal manipulation requires precise targeting of complex geometries, sound w…
Gradient descent optimization of acoustic holograms for transcranial focused ultrasound
Ahmed Sallam, Ceren Cengiz, Mihir Pewekar +4
Acoustic holographic lenses, also known as acoustic holograms, can change the phase of a transmitted wavefront in order to shape and construct complex ultrasound pressure fields, o…
