Abstract: Provided are systems using compression devices for a mammography unit, and methods of using the same, for example, in conjunction with imaging of a patient's breast. The instant mammography units can comprise at least one x-ray transparent inflatable chamber for containing a fluid. When fluid is introduced into the chamber, at least one surface of the chamber expands, breast motion is limited, and the breast and its vasculature are compressed. Fluid may also be released from the chamber, and as the chamber deflates, blood flow to the breast is restored, producing Korotkoff sounds that may be detected by a sound detection device. The detected sounds may be used to assist a radiologist in identifying regions of interest on a mammogram, and additionally or alternatively may be used to a enhance a computer-assisted detection (CAD) process by contributing an additional data parameter.

Abstract: Mammography units, mammography unit compression devices, and compression paddles for use with mammography units are described. Methods for their use in reducing patient discomfort during mammography are also described.

Abstract: Compression devices and mammography units using the same, and methods of using the same during imaging of a patient's breast are provided. The devices compress the breast against a bucky without the need for a traditional mammography unit compression paddle. The devices comprise at least one x-ray transparent inflatable chamber for containing a fluid, for example, a pressurized gas. In use, at least one surface of the chamber expands in the direction of the bucky. The devices secure the breast to the bucky by wrapping over the tube-side surface of the breast. Compressed air, for example, can be introduced, manually or automatically, to inflate the chamber. As the chamber expands, breast motion is limited and the breast is compressed against the surface of the bucky.

Abstract: A mammography comfort device comprises a compressible bolster and a separate x-ray transparent compressible pad. The bolster, affixed to the sides of a bucky, retains the pad on the imaging surface. A radiopaque identifier permanently affixed to the pad imparts information about the pad onto a mammogram. The comfort device can be used with an x-ray transparent disposable cover. A kit comprising at least two disposable covers and a comfort device can be supplied. A separate stretchable retainer holds a breast on the bucky and serves as an exposure equalizer. A compression paddle adapted with a bolster and a light transparent panel facilitates proper placement of a breast for compression. When the bolster comprises sections having different identification force deflection values the panel angles to the approximate shape of a compressed breast to distribute compression force more evenly. A vented panel provides for passage of warm air for patient comfort.
