    Abstract: A mammography apparatus including an x-ray source having an x-ray tube with one or more focal spots, a controller for controlling one or more parameters of the x-ray exposure, a digital image receptor configured to generate an x-ray image from objects positioned between the x-ray source and the digital image receptor, a specimen tray configured to receive samples from a biopsy, a positioning arm for positioning the specimen tray between the x-ray source and the digital image receptor, and a detector configured to detect the presence of the specimen tray when it is positioned. The controller is configured to adjust, select or configure one or more parameters of the x-ray exposure in reaction to the detection of the presence of the specimen tray in such a way that the one or more parameters are adapted to the specific needs of imaging biopsy specimens.

    Abstract: A method of continuous motion digital tomosynthesis includes exposing an object to a programed intensity x-ray beam as an x-ray source travels a pre-determined path, accumulating a signal charge from the x-ray beam, recording the accumulated signal charge into a digital frame image representing raw baseline data, acquiring information on the source's and the detector's position when the recording occurs, compressing the raw baseline data into compressed views, where each respective compressed view is formed by combining the raw data readouts of the respective compressed view, and reconstructing a volumetric breast image by processing each respective compressed view with a reconstruction process function that incorporates the acquired position information and a spatial sampling corresponding to the compressed views. A system configured to implement the method and a computer-readable medium are also disclosed.

    Abstract: A method and system for performing a biopsy guided by a 3D image of the object obtained from digital tomosynthesis is performed. The method includes applying a compression paddle to an object; performing a tomosynthesis scan; reconstructing at least a portion of the scan; locating a lesion using a displayed or reprojected marker to determine a location of the lesion; correlating the location of the lesion in the scan to a marker on the compression paddle or tool holder; and proposing a needle entry point of a biopsy tool based off of the correlation so that a needle or penetration device will effectively reach the lesion or target if it is inserted at the proposed entry point. A system for performing a biopsy is further disclosed. In one embodiment, the system comprises: a tomosynthesis imaging apparatus for performing a tomosynthesis scan comprising an x-ray source and an x-ray detector; at least one marker; a compression paddle; a controller; and a display screen for displaying at least a portion of a reproduction of a tomosynthesis scan generated by the imaging apparatus, wherein (i) the at least one marker is displayed on the reproduction, the marker being used to determine a lesion location or target, and (ii) the controller correlates the lesion location or target with the at least one marker and generates a proposed needle entry point based on the correlation so that a needle or penetration device will effectively reach the lesion or target if it is inserted at the proposed entry point.

    Abstract: A process for deploying an anti-scattering grid in a mammograph is provided. The mammograph comprises a radiation source configured to emit radiation for taking mammographic images of a patient, a radiation detector comprising a network of sensors arranged periodically with a first pitch, and an anti-scattering grid arranged between the source and the detector, the anti-scattering grid comprising radiation adsorbing strips arranged parallel to each other and distributed periodically with a second pitch. The process comprises: displacing the anti-scattering grid relative to the detector or displacing the detector relative to the anti-scattering grid during emission of radiation; adapting the second pitch to the first pitch, wherein displacement is perpendicular to the direction of the strips of the anti-scattering grid, the strips being arranged parallel to a side of the anti-scattering grid positioned against the patient, and altering the positions of the return points between successive periods of the displacement motion.
