    摘要： An apparatus and related methods for ultrasonically scanning a tissue volume are described, the apparatus being particularly advantageous in the context of freehand ultrasound assisted biopsy of the breast although readily applied to non-biopsy contexts and other body parts. The apparatus comprises a casing configured and dimensioned for single-handed manipulation relative to a surface of the tissue, and a texturably couplant-porous material sheet extending across an opening of the casing. The texturably couplant-porous material sheet has an outer side and an inner side relative to the casing, the outer side for compressively contacting the tissue surface. The apparatus further comprises an ultrasound transducer positioned against the inner side of the texturably couplant-porous material sheet and being mechanically translatable thereacross for volumetrically scanning the tissue volume therethrough.

    摘要： Versatile ultrasound scanning of a breast is described using an apparatus (1202) including a hand-manipulable compression/scanning assembly (1208). The compression/scanning assembly (1208) comprises an ultrasound transducer (1304) and a compressive member comprising an at least partially conformable membrane (1218) in a substantially taut state, the membrane (1218) having a first surface compressing the breast in a generally chestward direction and a second surface opposite the first surface. The compression/scanning assembly (1208) further comprises a transducer translation mechanism coupled to the ultrasound transducer (1304) and configured to sweep the ultrasound transducer across the second surface of the membrane to scan the breast while compressed in the generally chestward direction. Systemized and/or standardized ultrasonic scanning of a breast based on hand-manipulable scanners (1208, 1508) having substantially planar scanning surfaces is also described.

    摘要： Displaying breast ultrasound information on an interactive user interface is described, the user interface being useful in adjunctive ultrasound mammography environments and/or ultrasound-only mammography environments. Bilateral comparison is facilitated by a pairwise display of thick-slice images corresponding to analogous slab-like subvolumes in the left and right breasts. Coronal thick-slice imaging and convenient navigation on and among coronal thick-slice images is described. In one preferred embodiment, a nipple marker is displayed the coronal thick-slice image representing a projection of a nipple location thereupon. A convenient breast icon is also displayed including a cursor position indicator variably disposed thereon in a manner that reflects a relative position between the cursor and the nipple marker. Preferably, the breast icon is configured to at least roughly resemble a clock face, the center of the clock face representing the nipple marker location. Bookmark-centric and CAD-marker-centric navigation within and among thick-slice images is also described.
