Optical imaging and phototherapy in deep tissues face notable challenges due to light scattering. We use encoded acoustic holograms generate three-dimensional fields within the target medium, enabling instantaneous robust modulation of volumetric refractive index, thereby noninvasively controlling trajectory light. Through this approach, we achieved a remarkable 24.3% increase tissue heating rate vitro photothermal effect tests on porcine skin. In vivo photoacoustic mouse brain vasculature...
Three-dimensional (3D) cell culture has revolutionized life sciences, particularly in organoid technologies. Traditional bioscaffold materials, however, complicate the detachment of tumor organoids and hamper routine use organoid–immune cocultures. Here, we show an acoustic virtual 3D scaffold (AV-Scaf) method to achieve culture, enabling a direct-interacting coculture system. The self-organization process cells is facilitated by vortex field, which enables bioassembly ion channel...
Focused high-frequency acoustic waves are utilized in industrial non-destructive testing (NDT) on account of their exceptional spatial resolution and high sensitivity. However, the majority focusing methods currently adopted for transducers mechanical pressure lens focusing, which may inflict damage piezoelectric elements give rise to low transmission efficiency. In this paper, an efficient approach achieving self-focusing at frequency is proposed. This accomplished by utilizing half-concave...
The high-frequency ultrasonic transducers with larger bandwidths yield excellent imaging performance in the biomedical field. However, achieving perfect acoustic impedance matching from piezo-element to target medium operating frequency spectrum is still a challenge. Conventional layers are mostly fabricated by only one or two uniform materials which limited their property. We propose novel composite layer gradient based on 1-3 structure and multilevel theory. proposed gradient-composite...
Acoustic holography technology is widely used in the field of ultrasound due to its capability achieve complex acoustic fields. The traditional method based on single-phase holograms limited inability complete control with high dynamics and accuracy. Here, we propose a for constructing an holographic model, introducing ultrasonic array provide dynamic amplitude degrees freedom, combining dynamically controllable high-precision hologram highest accuracy range. This simulation has been proven...
