    • Apparatus and methods for focusing transcranial ultrasound. The systems described herein are advantageous for noninvasive neuromodulation and other transcranial ultrasound applications such as high intensity focused ultrasound (HIFU). In particular, described herein are compound acoustic lens apparatus having a short focal length for use with a transcranial ultrasound system, systems including methods of using them. These compound lens assemblies allow transcranial stimulation of even superficial cortical regions of the brain for ultrasound neuromodulation with a compact, single transducer element system at low (e.g., 0.2 to 1 MHz) frequencies with relatively large diameter (e.g., >15 mm) transducers applying 1 to 10 watts/cm2 of acoustic energy (spatial-peak, temporal-average intensity at the target brain region), and short focal length (e.g., between 15 and 35 mm).
    • 用于聚焦经颅超声的装置和方法。 本文描述的系统对于非侵入性神经调节和其它经颅超声应用如高强度聚焦超声(HIFU)是有利的。 特别地,这里描述了具有与经颅超声系统一起使用的短焦距的复合声透镜装置,包括使用它们的方法的系统。 这些复合透镜组件允许通过紧凑的单个换能器元件系统在低(例如,0.2至1MHz)的频率下使用相对大的直径(例如> 15mm)的换能器来进行超声神经调节的甚至脑表皮质区域的经颅刺激用于超声神经调节 1至10瓦特/平方厘米的声能(空间峰值,目标脑区域的时间平均强度)和短焦距(例如,15至35毫米)。
