Abstract: Examples of the present disclosure describe systems and methods for personalized breast imaging. In aspects, a first set of patient attributes may be collected. The first set of patient attributes may relate to, or be used to determine, for example, breast size, breast thickness, and/or three-dimensional (3D) breast shape. The first set of patient attributes may be used to customize image acquisition parameters for the patient. A second set of patient attributes may also be collected. The second set of patient attributes may relate to, or be used to determine, for example, breast elasticity and breast density. The second set of patient attributes may be used to customize breast compression parameters for the patient. The customized image acquisition parameters and breast compression parameters may then be used to perform one or more procedures (e.g., an imaging procedure, a biopsy procedure, etc.) on the patient's breast.

Abstract: A biopsy site marker configured to expand upon deployment into a biopsy cavity, and visible under several different imaging modalities, comprises a superabsorbent hydrogel component and a radiopaque element. The hydrogel is in a compressed, dehydrated state prior to deployment to facilitate placement of the marker within the biopsy site, and thereafter expands upon deployment in the biopsy site. Such expansion limits migration of the site marker.

Abstract: Examples of the present disclosure describe systems and methods for the long-term, real-time active monitoring of a wireless implant. In aspects, a wireless biosensor may be implanted in a breast biopsy cavity. The biosensor may detect biochemical parameter data of the breast biopsy cavity and the human body. The biosensor may transmit the detected biochemical parameter data in real-time to a surveillance system wirelessly coupled to the biosensor. The surveillance system may then facilitate the evaluation of the biochemical parameter data. In examples, the evaluation may comprise detecting trends in a tumors microenvironment, monitoring the progress of a treatment, or adjusting a treatment to tailor a personalized treatment.

Abstract: For a biopsy guided by contrast-enhanced x-ray imaging, a breast imaging system may image a patient's breast subsequent to injection of contrast agent to locate a site for biopsy and/or position a biopsy device relative to the site. Once a tissue specimen is removed from the site for diagnostic evaluation, a confirmation that the specimen was removed from an intended area of interest for biopsy is performed using the systems and methods described herein. For example, the breast imaging system and/or a separate specimen imaging system may capture high and low energy images of the specimen, subtract the low energy image from the high energy image to generate a subtracted image of the specimen, and determine, based on the subtracted image, that the contrast agent is present within the specimen to confirm the site from which the specimen was removed is the intended site for biopsy.

Abstract: A method of determining performance characteristics of a breast compression paddle utilized in a breast imaging system includes receiving a force application signal, wherein the force application signal is associated with an application of a compressive force by the breast imaging system with the breast compression paddle to a breast of a patient. The method applies the force application signal to an algorithm to obtain a reduction value. The reduction value is subtracted from a known paddle performance value for the breast compression paddle to obtain an updated paddle performance value for the breast compression paddle.
