Estimating the term…
A method includes transmitting a focused ultrasound wave into a medium to form (i) an ultrasound intensity well within the medium that exhibits a first range of acoustic pressure and (ii) a surrounding region of the medium that surrounds the ultrasound intensity well and exhibits a second range of acoustic pressure that exceeds the first range of acoustic pressure. The method further includes confining an object within the ultrasound intensity well. Additionally, an acoustic lens is configured to be acoustically coupled to an acoustic transducer. The acoustic lens has a varying longitudinal thickness that increases proportionally with respect to increasing azimuth angle of the acoustic lens. Another acoustic lens is configured to be acoustically coupled to an acoustic that increases proportionally with respect to increasing azimuth angle of the segment.
A method comprising:
An acoustic lens configured to be acoustically coupled to an acoustic transducer, the acoustic lens having a varying longitudinal thickness that increases proportionally with respect to increasing azimuth angle of the acoustic lens.
An acoustic lens configured to be acoustically coupled to an acoustic transducer, the acoustic lens comprising a plurality of segments, each of the plurality of segments having a varying longitudinal thickness that increases proportionally with respect to increasing azimuth angle of the segment.
A device comprising:
