  • Patent number: 12193886
    Abstract: A tilted needle biopsy assembly is provided for mounting on an x-ray system. Because the biopsy needle is angled relative to at least one of the detector and the x-ray source, x-ray imaging may be performed during the biopsy procedure without interference by the biopsy device. The angled biopsy needle additionally allows improved access to the axilla and chest wall of the patient. The stereotactic biopsy device of the present invention may be coupled to any x-ray system, whether upright or prone, including but not limited to mammography systems, tomosynthesis systems, and combination mammography/tomosynthesis systems. The system flexibly supports the use of any mode of image capture (i.e., scout, two dimensional mammogram, three-dimensional reconstructed volume) for either or both target visualization and target localization. With such an arrangement, a needle biopsy assembly having improved patient coverage is provided for use with a variety of different x-ray imaging platforms.

  • Patent number: 12196771
    Abstract: A system for analysis of biopsy samples includes a tissue sample transport mechanism linking a biopsy sample excision tool to a tissue sample holder disposed in a staging area of an analysis unit. The tissue sample is automatically transported from the excision tool to the specimen holder, where the tissue sample is analyzed in the staging area of the analysis unit. The transport mechanism may include tubing and a vacuum source. The tissue sample holder may be configured to slow or temporarily stop a tissue sample for individual analysis, or collect multiple tissue samples for analysis as a group. A tissue sample sorting mechanism may be employed that allows separation of specimens that can be correlated to the analysis.

  • Publication number: 20250009463
    Abstract: A station for tomotactic-guided biopsy in prone includes a table with an aperture, and a tomosynthesis imaging system. A biopsy gun can be mounted on a stage arm assembly disposed below the table. The imaging system and stage arm assembly can be independently rotated and linearly repositioned in one or more dimensions, thereby allowing the tomotactic scan axis to be located relative to a breast being imaged.

  • Patent number: 12161496
    Abstract: Systems and methods for reducing X-ray scatter during breast imaging, and more specifically during tomosynthesis imaging. In one embodiment, an anti-scatter grid having a plurality of septa may be configured to be positioned relative to an X-ray imaging device such that each septum of the plurality of septa extends along a direction substantially parallel to a coronal plane of a subject during imaging of the subject using the X-ray imaging device. The X-ray imaging device may be operable in a tomosynthesis mode for imaging of a breast of the subject and may include the anti-scatter grid disposed between a breast platform and the X-ray detector. The anti-scatter grid may be configured to move in a direction substantially parallel to a sagittal plane of the subject during tomosynthesis imaging.

  • Patent number: 12144668
    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.

  • Publication number: 20240245364
    Abstract: An x-ray breast imaging system comprising a compression paddle in which the compression paddle comprises a front wall and a bottom wall. The front wall is configured to be adjacent and face a chest wall of a patient during imaging and the bottom wall configured to be adjacent a length of a top of a compressed breast. The bottom wall extends away from the patient's chest wall, wherein the bottom wall comprises a first portion and a second portion such that the second portion is between the front wall and the first portion. The first portion is generally non-coplanar to the second portion, wherein the compression paddle is movable along a craniocaudal axis. The x-ray breast imaging system also comprises a non-rigid jacket releasably secured to the compression paddle, the non-rigid jacket positioned between the compression paddle and the patient.

  • Publication number: 20240164744
    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.

  • Publication number: 20230355203
    Abstract: A multi-modality cancer screening and diagnosis system is provided that allows cancer screening and diagnosis of a patient using at least two different and sequential three-dimensional imaging techniques without patient repositioning. The system includes a first three-dimensional image acquisition device, a second three-dimensional image acquisition device having a probe with a transmitter mounted thereon, and a positioning paddle for positioning and immobilizing an object to be imaged during the cancer screening and diagnosis procedure. The positioning paddle is designed to facilitate visualization of the breast in both three-dimensional modalities without movement of the patient, and preferably is designed to position the patient with comfort during a diagnosis procedure which uses both imaging modalities.
