A method apparatus and computer product for imaging a human breast to map the breast ductal tree is disclosed. First, a breast is diffusion tensor imaged with high spatial resolution. Then the breast ductal tree is tracked using a protocol for breast based on echo-planar imaging (EPI) diffusion designed for optimizing diffusion weightings (b values), number of non-collinear directions for tensor calculations, diffusion, echo and repetition times, spatial resolution, signal to noise, scanning time and a sequence for fat suppression. The diffusion tensor is calculated by a non-linear best fit algorithm and then diagonalized with principal component analysis to three eigen vectors and their corresponding eigen values. A vector field map is obtained for tracking of breast ducts of the ductal trees along the direction of the 1st eigenvector v1 and the ductal tree is displayed on a voxel by voxel basis in parametric images using color coding and vector pointing.

An apparatus and method for imaging a breast is provided. The apparatus for imaging a breast includes a first X-ray emission unit configured to emit an X-ray of a first dose to a breast, a second X-ray emission unit configured to emit one or more X-rays of a second dose to the breast, the first dose being greater than the second dose, an X-ray detection unit configured to detect the X-ray of the first dose or the one or more X-rays of the second dose to thereby generate one or more image frames regarding the breast, and an image generation unit configured to generate image data regarding the breast based on the generated one or more image frames.

A subject information acquisition unit of a mammary gland amount calculation unit acquires the thickness and the mammary gland amount of the breast based on a low voltage image. An absorption coefficient acquisition unit acquires an absorption coefficient of fat and an absorption coefficient of mammary gland with reference to the relationship between the thickness of the breast and the X-ray absorption coefficient, which is calculated in advance according to the energy distribution and the substance forming the breast. A calculation unit calculates a new thickness and a new mammary gland amount of the breast based on the low voltage image, a high voltage image, a tube voltage at the time of imaging, the absorption coefficient of fat, and the absorption coefficient of mammary gland.

A first detection unit detects a breast region and a skin line from a breast image, and a first index value calculation unit calculates a first index value indicating the single composition degree of the breast region. A second detection unit detects a boundary between the adipose tissue and the mammary gland tissue in a predetermined range from the skin line toward the inside of the breast region in the breast image. A second index value acquisition unit acquires a second index value indicating the degree of clogging of mammary glands with respect to the breast region based on at least one of the strength of the boundary or the distance from the skin line. An identification unit identifies the type of the breast based on the first and second index values.

A hardness deriving device includes: an acquisition section configured to acquire plural ultrasound images obtained by ultrasound imaging a breast in a state in which the breast is pressed by a pressing member at a plurality of different pressures; and a deriving section configured to find an amount of change at corresponding points between the plural ultrasound images acquired by the acquisition section, and to derive information indicating a hardness of tissue of the breast based on the amount of change at the corresponding points.

The invention provides a method for dividing a breast three-dimensional image and a device thereof. The method for dividing a breast three-dimensional image comprises a step of inputting the breast three-dimensional image and converting the breast three-dimensional image into a two-dimensional image, a step of obtaining the object boundary line of two-dimensional image by a dynamic programming method, and a step of reconstructing the division result of a breast based on the object boundary line of two-dimensional image, wherein the boundary line is the position of the breast in the two-dimensional image after the outer surface of the breast is converted. According to the scheme, the gray, gradient and shape features of the breast three-dimensional image are combined, and the automatic three-dimensional division is accurately and effectively realized.

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.

A method for defining a region of interest in a radiation image of a breast based on the result of shape analysis applied to a skin line estimate determined in the radiation image.

The invention relates to the technical field of bras, in particular to a breast support, a preparation method thereof, a bra using the support and a preparation method for the bra. The breast support comprises a breast base and two bearing cups, wherein the breast base comprises two breast base bodies which are connected through a fixed supporting surface; the fixed supporting surface extends respectively along the bottom of the two breast base bodies to form a lower clinging edge; the two bearing cups are respectively arranged above the breast base body and are respectively provided with a plurality of air holes; the breast support is a TPU (thermoplastic polyurethanes) breast support. The breast support has the advantages of good breathability and high supporting force, the generation of breast cancer and liver channel extrusion can be reduced, and an effect on gathering can be achieved. The bra which applies the breast support is softer than a wire bra and is more stylish and lighter than a common wireless bra, the bra has the advantages of good comfort level, breathability and supporting force, and meanwhile, the technical problems that a cup shape made of vertical cotton is retracted after the bra is washed with water for a long time in the field can be solved.

A mammography apparatus includes a support plate for supporting a breast of a patient, a compression plate movable toward and away from the support plate for compressing the breast against the support plate, and a controller configured to control movement of the compression plate toward and away from the support plate. The controller is configured to adjust at least one of a rate of compression and a pressure applied to the breast based on a measurement of at least one of a diastolic pressure and a systolic pressure of the patient taken during at least one of a compression phase and a clamping phase of the mammography apparatus.
