Abstract
Description
Technical Field
[0001] The present application relates to the field of transcranial ultrasonic vortex control, and in particular to a transcranial acoustic vortex dynamic control method, equipment, medium and product. Background Art
[0002] With the continuous advancement of neuromodulation, brain disease intervention, and basic research on brain function, people have placed higher demands on the precise manipulation of ultrasound in the brain. In recent years, acoustic vortexes, as a form of sound field with a unique rotating wavefront and angular momentum, have shown great potential in particle capture, thrombus manipulation, targeted drug delivery in the brain, and neural circuit regulation. However, due to the complex structure, high acoustic impedance, and uneven thickness of the human skull, it causes significant scattering, reflection, and distortion of sound waves, severely limiting the accurate formation of vortex sound fields in the skull.
[0003] Currently, researchers mainly use two types of schemes to achieve the generation of transcranial vortex sound fields: one is a multi-element phased array system, which achieves dynamic wavefront synthesis by adjusting the phase difference between the elements; the other is an acoustic holographic lens, which uses multi-layer structural materials or phase encoding technology to form a fixed-shape three-dimensional sound field. Although these methods have achieved vortex sound fields or intracranial focusing to varying degrees, they still have significant limitations. For example, the phased array system equipment is complex, expensive, and highly dependent on the drive and control system, making it difficult to apply on a large scale in basic research or clinical scenarios. While the existing static acoustic lens can correct skull distortion once, once the design is completed, its focal position and sound field shape are fixed, lacking flexibility and adjustability.
[0004] Based on the above, although the current acoustic vortex generation schemes based on phased arrays or holographic lenses have achieved the goal of transcranial sound field control in principle, multiple studies and practical applications have found that these methods have major defects in engineering feasibility, cost control and structural flexibility. First, the complex multi-channel phased array structure requires a high-precision electronic control system, which not only increases the hardware threshold and maintenance costs, but also limits the system's integration and portability. Second, although traditional gradient phase lenses or holographic structures can achieve partial sound field control under experimental conditions, they cannot adapt to the flexible adjustment of the target focus in three-dimensional space, and cannot meet the use requirements of multiple target areas and variable focus in clinical or research.
[0005] Furthermore, existing technologies rarely consider the coupling relationship between acoustic field morphology (such as vortices) and frequency response, resulting in significant performance degradation in multi-frequency applications. For example, the vortex focus can shift or even become defocused at different frequencies, affecting application stability under varying acoustic conditions. This drawback stems from the lack of frequency-adaptive properties in conventional lens structures, making it impossible to automatically adjust the acoustic field morphology based on sound wave propagation conditions.
[0006] Therefore, there is an urgent need for a new solution with a simple structure, controllable cost, easy manufacturing, and the ability to perform skull compensation, vortex synthesis, and focus control, to provide a more flexible and practical technical platform for brain science research and neurointervention applications.
