1. A method of imaging a specular object and a target anatomy in a tissue using ultrasound, the method comprising:
a tissue imaging step comprising:
transmitting first sound waves into a volumetric region of the tissue, the volumetric region including the target anatomy located in a target plane;
receiving echoes of said first sound waves from the target plane; and
processing said received echoes to produce a two-dimensional tissue image;
a specular object imaging step comprising:
selecting elevations for imaging the specular object based on an elevation of the target plane used for imaging the target anatomy in the tissue imaging step;
transmitting second sound waves into said volumetric region of the tissue based on the selected elevations, the volumetric region including the specular object;
receiving echoes of said second sound waves from a plurality of image planes, said plurality of image planes each corresponding to one of the selected elevations; and
processing the echoes received from the plurality of image planes to produce a set of two-dimensional specular object images, wherein the method further comprises:
performing a first combination of the set of two-dimensional specular object images into a first combined two-dimensional specular object image, wherein performing the first combination of the set of two-dimensional specular object images includes coding each of the two-dimensional specular object images based on an elevation position of the two-dimensional specular object image relative to the target plane such that the first combined two-dimensional specular object image indicates a portion of the specular object that is in front of the target plane and a portion of the specular object that is behind the target plane;
performing a second combination of the two-dimensional tissue image and the first combined two-dimensional specular object image to generate a second combined two-dimensional image; and
displaying the second combined two-dimensional image.
