Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A compression assembly is coupled to the gantry of an ultrasound breast imaging system. The compression assembly includes a pair of compression paddles mounted on a positioning track. Each compression paddle houses a transducer and has a compression material surface for patient contact. A motor moves the compression paddles along the positioning track to immobilize the breast for ultrasound imaging.

Abstract: 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.

Abstract: A curved compression element, such as a breast compression paddle, and imaging systems and methods for use with curved compression elements. A system may include a radiation source, a detector, and a curved compression element. Operations are performed that include receiving image data from the detector; accessing a correction map for the at least one compression paddle; correcting the image data based on the correction map to generate a corrected image data; and generating an image of the breast based on the corrected image data. The breast compression element generally has no sharp edges, but rather has smooth edges and transitions between surfaces. The breast compression paddle also includes a flexible material that spans a portion of a curved bottom surface of the breast compression paddle to define a gap. The flexible material may be a thin-film material such as a shrink wrap.
