Systems, methods, and related computer program products for ultrasonic examination of a tissue volume, such as a human breast, are described. A handheld volumetric ultrasound scanning probe, which is characterized by a two-dimensional scan area with a substantially rigid cap extending across the two-dimensional scan area, is provided with a texturably couplant-porous material sheet covering the substantially rigid cap over at least a portion of the two-dimensional scan area. The texturably couplant-porous material sheet facilitates positional stability of the handheld volumetric ultrasound scanning probe while positioned against a skin surface of the tissue volume. Advantageously, while the texturably couplant-porous material sheet brings about a more stable physical interface at the skin surface, the texturably couplant-porous material sheet brings about little or no degradation in acquired image quality. Also described are systems and related methods for elastography imaging using the handheld volumetric ultrasound scanning probe.
