APPARATUS AND METHOD FOR THE MANIPULATION OF OBJECTS USING ULTRASOUND

摘要

A method and apparatus for manipulating particles. The apparatus comprising an ultrasound source for providing a variable ultrasound signal within a region of interest, and a controller connected to the ultrasound source such that it provides a control signal to the ultrasound source. The variable ultrasound signal creates a pressure field within the region of interest, the shape and/or position of which can be altered by changing the control signal input to the ultrasound source such that a particle within the region of interest will move in response to changes in the pressure field.
