Skull-Conforming Acoustic Holographic Lenses for Transcranial Targeting
Ceren Cengiz, Mihir Pewekar, Hrishikesh Kulkarni +6
Transcranial focused ultrasound (tFUS) offers noninvasive access to deep brain circuits but remains limited by skull-induced phase aberration, acoustic impedance mismatch, and poor…
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…
Holographic Thermal Mapping Using Acoustic Lenses
Ceren Cengiz, Shima Shahab
Acoustic holographic lenses (AHLs) show great potential for sound manipulation. These lenses store the phase and amplitude profile of the desired wavefront when illuminated by a si…
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…
