1. A method for presenting breast ultrasound information, comprising: generating a first thick-slice image representing a sonographic property within a first slab subvolume of a chestwardly compressed first breast of a patient by (i) imaging the chestwardly compressed first breast with an ultrasound imaging apparatus to thereby derive a first plurality of thin-slice images and (ii) computer-processing said first plurality of thin-slice images to thereby generate said first thick-slice image; generating a second thick-slice image representing said sonographic property within a second slab subvolume of a chestwardly compressed second breast of the patient by (i) imaging the chestwardly compressed second breast to thereby derive a second plurality of thin-slice images and (ii) computer-processing said second plurality of thin-slice images to thereby generate said second thick-slice image, said first and second slab subvolumes occupying generally similar positions within the first and second breasts, respectively, said first and second slab subvolumes each being substantially parallel to a coronal plane of the patient; and displaying said first and second thick-slice image adjacent each other for comparison of the first and second breasts relative to said sonographic property.
