摘要：
Ultrasound devices configured to perform high-intensity focused ultrasound (HIFU) are described. An ultrasound device may include HIFU units configured to emit high acoustic intensities. Multiple ultrasound devices may be disposed on a substrate, which may be configured to be flexed so that the direction of emission of the ultrasound devices can be mechanically controlled. Additionally, or alternatively, the ultrasound beams produced by different ultrasound devices may be electronically oriented by adjusting the phases of the signals with which each element of a device is driven. For example, multiple phased arrays of ultrasound devices may be used to concentrate ultrasound energy into a desired location. In some embodiments, the time at which different ultrasound signals are emitted may be controlled, for example to ensure that the combined signal has at least a desired intensity.
