Abstract: 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.

Abstract: 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 and elasticity detectors configured to determine characteristics of the target area of a human body based on the elasticity of the target area. The elasticity detectors may determine, e.g., whether the target area is healthy, and if not, the type cell in need of treatment (e.g., the type of cancer cell present in the target area). In one example, the elasticity detectors may be configured to determine the stiffness of the target area, which may provide an indication as to the type of cell present in the area, by estimating the velocity of a shear wave propagating away from the target area. The shear wave may arise in response to the application of an ultrasound wave to the target area.
