Abstract: A breast compression paddle includes a bracket, a rigid substrate, and a foam compressive element. The bracket removably secures the breast compression paddle to an imaging system. The rigid substrate is secured to the bracket and includes a first edge and a second edge disposed opposite the first edge. The foam compressive element is slidably secured to the rigid substrate.

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 a 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 the 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.

Abstract: A cryogen delivery system includes a probe configured to deliver a cryogenic fluid to a treatment location, a cryogen inlet configured to interface with a cryogenic fluid supply vessel to transfer cryogenic fluid from the cryogenic fluid supply vessel to the probe, a support structure configured to position the cryogenic fluid supply vessel relative to the cryogen inlet, and a sensor coupled to the support structure. The sensor is configured to generate a signal indicative of a weight of a cryogenic fluid contained in the cryogenic fluid supply vessel. Devices and methods relate to cryogen delivery systems.

Abstract: A method of imaging a breast of a patient using an imaging system includes applying, with a first component of the imaging system, a compressive force to the breast. A second component of the imaging system is positioned in a start position. The imaging system sends a first guidance signal to the patient. An imaging procedure of the breast is performed with the second component of the imaging system. Subsequent to performing the imaging procedure, a second guidance signal is sent to the patient.

Abstract: 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.

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: An apparatus for holding a breast compression paddle, includes a base, a lip connected to and extending substantially orthogonal from the base, an arm connected to and extending substantially orthogonal from the base and disposed substantially parallel to the lip, and a tine connected to and extending at an angle to the arm. The lip defines a lip plane, and the tine is oriented towards the lip plane. The apparatus is configured to hold and support a compression paddle.
