Ultrasound Beam shaping We are developing optically-inspired ultrasonic techniques to manipulate the emitted acoustic field in order to produce images with improved resolution and contrast. By controlling the phase and apodization of each individual element within the transducer array, the direction and shape of the ultrasound beam can be controlled and designed to create a desired pattern. Examples include the development of acoustical structured illumination for super resolution imaging, point spread function engineering, extended depth of focus, and frequency multiplexing for enhanced imaging.
