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 method of imaging a breast compressed with a paddle including a foam compressive element. The method emits an x-ray energy from an x-ray source towards the breast and the foam compressive element and a marker disposed adjacent the foam compressive element. The x-ray energy is emitted over a predetermined time period. The marker includes a physical characteristic. The x-ray energy is detected at a detector disposed opposite the breast from the x-ray source. An image of the compressed breast and the marker is generated based on the detected x-ray energy. The marker in the generated image includes an image characteristic associated with the physical characteristic. The image characteristic is compared to the physical characteristic. A signal is sent when the image characteristic deviates from the physical characteristic by a threshold.

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: Examples of the present disclosure describe systems and methods for using machine learning (ML) to predict optimal exposure technique for acquiring mammographic images. In aspects, training data may be collected from one or more data sources. The training data may comprise sample data of patient attribute data and sample image attribute data, image metadata, image pixel data, and/or exposure technique parameters. The training data may be used to train an ML model to determine the optimal exposure technique parameters for acquiring mammographic images of a patient. After the ML model has been trained, patient data that is collected from a patient during a patient visit may be provided as input to the ML model. The ML model may output optimal exposure technique parameters for the patient in real-time. The real-time output of the ML model may be used to generate one or more mammographic images of the patient.

Abstract: A method of imaging a breast of a patient with a breast imaging system includes supporting the breast on a breast support platform. A compressive force is applied to the breast with a breast immobilization element including a rigid substrate, a foam compressive element secured below the rigid substrate, and a force sensor. The foam compressive element is in contact with the breast during application of the compressive force. A force signal is detected at the force sensor based on the applied compressive force. A compressed thickness of the breast proximate the force sensor is determined based at least in part on the detected force signal at the force sensor. An automatic exposure control is set based at least in part on the determined thickness of the breast proximate the force sensor.
