  • Publication number: 20160022364
    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.

  • Publication number: 20150313674
    Abstract: A breast biopsy lateral arm system includes a removable gun mount which attaches to a carriage that traverses along an X-axis defined by a lateral arm in order to position a biopsy needle relative to a patient. The carriage rides along the lateral arm on self-adjusting rollers which are loaded against the lateral arm by spring members. A cam-actuated carriage slide lock can be used to secure the carriage in a desired position relative to the lateral arm. A cam-actuated removable gun mount lock allows the gun mount to be quickly changed and offset orthogonally with respect to the X-axis. An X-axis stop can be used to establish a position to which the carriage can be returned with accuracy.

  • Publication number: 20140301529
    Abstract: A method and an apparatus for estimating a geometric thickness of a breast in mammography/tomosynthesis or in other x-ray procedures, by imaging markers that are in the path of x-rays passing through the imaged object. The markings can be selected to be visible or to be invisible when the composite markings/breast image is viewed in clinical settings. If desired, the contribution of the markers to the image can be removed through further processing. The resulting information can be used determining the geometric thickness of the body being x-rayed and thus setting imaging parameters that are thickness-related, and for other purposes. The method and apparatus also have application in other types of x-ray imaging.

  • Publication number: 20140257135
    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: 20140058286
    Abstract: The table for performing breast biopsies is characterized by features that enhance patient comfort and facilitate performance of the biopsy. An opening in the table allowing the breast to extend below the table top is formed in a removable insert. An area of the insert includes padding. An alternate insert having a different diameter opening may be selected based on patient breast size. Another insert having an asymmetrical opening may accommodate the patient's arm when it is desirable to position both the arm and breast of the patient below the table top. The table top is contoured such that symmetrical distal end sections are elevated relative to a central section to support the patient in multiple positions. A removable pad may be placed over the insert. An end portion for padding the hip of the patient is thicker than an end portion for padding the head/neck of the patient.

  • Patent number: 8559595
    Abstract: A mammographic imaging system is optimized for use with a single fixed size flat panel digital image receptor. It accommodates compression devices (paddles) of varying sizes, and positions them properly in the field of view of the image receptor. When a compression paddle with size smaller than the field of view of the image receptor is used, the compression paddle can be shifted laterally in the direction parallel to the chest wall, so as to facilitate different views of different size breasts, and permit the image receptor to image as much of the desired tissue as possible. An automatic x-ray collimator restricts the x-ray illumination of the breast in accordance with compression paddle size and location in the field of view. An anti-scatter grid, mounted inside the image receptor enclosure, just below the top cover of the enclosure, can be retracted out of the field of view of the image receptor for use in magnification imaging.

  • Patent number: 8452379
    Abstract: A method and system for producing tomosynthetic images of a patient's breast. An x-ray source that delivers x-rays through a breast immobilized and compressed between a compression paddle and a breast platform and form an image at a digital x-ray receptor panel. Multiple x-ray images are taken as the x-ray source and the receptor move relative to the immobilized breast. In one preferred embodiment, the x-ray source travels from ?15° to +15°. The source can travel in an arc around the breast while the receptor travels linearly while remaining parallel and at the same distance from the breast platform. The sets of x-ray image data taken at different angles are combined to form tomosynthetic images that can be viewed in different formats, alone or as an adjunct to conventional mammograms.

  • Publication number: 20130072816
    Abstract: A biopsy device includes a lateral member; a gun mount configured to support a biopsy gun, the gun mount being connected to the lateral member and movable along a first axis with respect to the lateral member, and a sensor which detects a position of the gun mount along the first axis with respect to the lateral member and generates positional data which is provided to an interface module. The gun mount can also be reconfigured in orientations which are offset in a dimension which is orthogonal to the first axis, orientations rotationally offset about the first axis or an axis parallel to the first axis. The lateral member can be in right hand and left hand orientations. Various sensors detect these reconfigurations and provide corresponding data to the interface module for additional calculations and display.

  • Publication number: 20120250969
    Abstract: An integrated tomosynthesis/molecular breast imaging device having improved sensitivity includes tomosynthesis imaging components and molecular breast imaging components. The imaging components may be used individually or in combination to provide a system with improved sensitivity and specificity. Molecular imaging components may be smoothly advanced or withdrawn depending upon the desired imaging mode. The system supports both PET and SPECT imaging and enables SPECT collimation to be modified in accordance with image capture requirements.

  • Publication number: 20120150034
    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.
