Abstract: A system for providing contrast enhanced ultrasound (CEUS) images is described. The CEUS system includes an ultrasound probe adapted to provide the ultrasound images; a processor configured to determine out-of-plane frames of the ultrasound images, and remove the out-of-plane frames from the ultrasound images based on a criterion to provide an optimized set of frames; and a display in communication with the processor and configured to display the optimized set of frames.

Abstract: A dipole antenna includes a substrate, a first radiation element, a second radiation element. The first radiation element disposed on the substrate includes a first bent portion and a second bent portion. The second radiation element disposed on the substrate includes a third bent portion and a fourth bent portion. A first feed-in point is disposed between the first bent portion and the second bent portion and a second feed-in point is disposed between the third bent portion and the fourth bent portion. The first radiation element and the second radiation element are spaced apart by a gap and have reflection symmetry with respect to a symmetrical axis.
