摘要： The housing for a breast imaging system contains an x-ray source and is configured to rotate relative to the breast. The housing for an x-ray receptor has a breast support platform and extends from an arm assembly which rotates independently from the x-ray source housing. A compression arm assembly connected to the arm assembly moves between a first linear position proximate the x-ray receptor housing and a second linear position distal the x-ray receptor housing. A pair of extension arms are pivotably connected to a strut which removably secures a compression paddle to the compression arm assembly substrate. The extension arms move between a first pivoted position substantially aligned with the strut and a second pivoted position disposed at an angle to the strut.

摘要： A method of imaging a breast compressed with a paddle including a foam compressive element. The method emits an x-ray energy from an x-ray source towards the breast and the foam compressive element and a marker disposed adjacent the foam compressive element. The x-ray energy is emitted over a predetermined time period. The marker includes a physical characteristic. The x-ray energy is detected at a detector disposed opposite the breast from the x-ray source. An image of the compressed breast and the marker is generated based on the detected x-ray energy. The marker in the generated image includes an image characteristic associated with the physical characteristic. The image characteristic is compared to the physical characteristic. A signal is sent when the image characteristic deviates from the physical characteristic by a threshold.

摘要： A method of imaging a breast compressed with a foam paddle includes emitting an x-ray energy from an x-ray source towards the breast and the foam paddle having a plurality of upper markers and a plurality of lower markers, wherein the plurality of lower markers are movable relative to the upper markers. The x-ray energy is detected at a detector disposed opposite the breast from the x-ray source. An image of the compressed breast is generated based on the detected x-ray energy. At least one of the plurality of upper markers and at least one of the plurality of lower markers is identified in the image. A thickness of the compressed breast at a plurality of thickness locations is determined, wherein each of the plurality of thickness locations corresponds to at least one of the plurality of lower markers.

摘要： Systems and methods for breast x-ray tomosynthesis that enhance spatial resolution in the direction in which the breast is flattened for examination. In addition to x-ray data acquisition of 2D projection tomosynthesis images ETp1 over a shorter source trajectory similar to known breast tomosynthesis, supplemental 2D images ETp2 are taken over a longer source trajectory and the two sets of projection images are processed into breast slice images ETr that exhibit enhanced spatial resolution, including in the thickness direction of the breast. Additional features include breast CT of an upright patient's flattened breast, multi-mode tomosynthesis, and shielding the patient from moving equipment.

摘要： A multi-mode system and method for imaging a patient's breast with x-rays in one or more of a CT mode, a narrow-angle tomosynthesis mode, a wide angle tomosynthesis mode, and a mammography mode, using essentially the same equipment, on one or more compressions or immobilizations of the breast.

摘要： Systems and methods for multi-modality (MMI) imaging of a specimen (136) are disclosed. A specimen may be imaged with a first modality at a first plurality of imaging angles and imaged with a second modality at a second plurality of imaging angles. The first modality may be associated with a different x-ray dose than the second modality. Additionally, one or more angles of the first plurality of imaging angles may be different from the second plurality of imaging angles. Image data obtained from imaging with each modality is used to compile reconstructed images of the specimen. A portion of the reconstructed images that includes a micro-calcification may be reconstructed based on image data from the modality associated with a higher dose.
