摘要:
Methods, systems, and related computer program products for the non-invasive spectrophotometric monitoring of a biological volume having multiple tissue layers are described. Aggregate absorption and scattering properties are measured for each of a plurality of predetermined source-detector separation distances along a surface of the biological volume, the measurement being based on a model of the biological volume as a single-layer, semi-infinite, homogeneous volume. A predetermined multi-layer tissue model is retrieved that characterizes a mathematical relationship among (a) absorption and scattering properties of each layer of a multi-layer tissue structure, and (b) aggregate absorption and scattering properties of the multi-layer tissue structure as would be measured at selected source-detector separation distances along a surface thereof. The measured aggregate absorption and scattering properties are processed in conjunction with the predetermined multi-layer tissue model to compute therefrom a deep-layer-specific absorption property corresponding to the relatively deep tissue layer.

A modular, flexible architecture for offering full-field breast ultrasound (FFBU) functionality and general-purpose ultrasound functionality in a single system is described. A conventional, general-purpose ultrasound system (202) is modified with an FFBU toolkit to create a dual-capability ultrasound system (200), the dual-capability ultrasound system (200) being able to accommodate both general-purpose ultrasound functionality and FFBU functionality, using a single ultrasound engine (112). Among other advantages, real-world clinical environments may enjoy cost savings for initial system procurement, space savings on clinic floors, easier and less expensive system upgrades, and the ability to use a single system and user interface for both FFBU screening and for follow-up diagnosis, biopsy, etc. Among other advantages from an ultrasound manufacturer's perspective are the ability to quickly and/or more easily come to market with an FFBU-related offering by modifying their existing general-purpose ultrasound systems (202) with FFBU toolkits to quickly create dual-capability ultrasound systems (200).
摘要:
Navigation among breast ultrasound volumes derived from different volumetric ultrasonic scans of a same breast is described. On a display of a breast ultrasound workstation, a first image derived from a first ultrasonic volume is displayed. A user election of a source region of interest (ROI) in the first image is received. A destination ROI within a second ultrasonic volume is identified that at least roughly corresponds to a same locality of tissue in the breast as the source ROI. A second image derived from the second ultrasonic volume and including the destination ROI is displayed, the destination ROI being highlighted.

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.

摘要:
An apparatus and related methods for scanning a breast are described, the apparatus comprising a frame defining an orifice shaped to allow the breast to be received therein, a compressive member secured to the frame across the orifice that compresses the received breast toward the patient's chest wall, and a transducer positioned in acoustic communication with the compressive member for imaging the breast therethrough. The frame holds a reservoir of acoustically conductive fluid that maintains the transducer in acoustic communication with the compressive member. In different preferred embodiments having different advantages, the compressive member comprises a flexible elastic membrane, a flexible inelastic membrane, or a rigid sonolucent plastic preformed into the shape of a chestwardly-compressed breast. Where the transducer comprises one or more linear array probes, various probe orientations and trajectories are described for generating a three-dimensional volumetric representation of the breast having reduced nipple shadow effects.
