An imaging system includes an x-ray tube head, a support arm, and a compression system coupled to the support arm. The compression system is independently rotatable relative to the x-ray tube head and includes a compression paddle, a support platform, and an x-ray receptor. The imaging system also includes a light assembly coupled to the support arm and disposed above the compression paddle. The light assembly is configured to direct one or more beams of light towards the support platform.

While performing a tomosynthesis procedure, the breast of a patient is compressed between two compression elements to create an imaging condition. Foam is secured to the rigid substrate of a one of the compression elements. The patient's chest wall is aligned with the leading edge surface of the foam. The inner side of the breast is disposed proximate the lateral edge surface of the foam and the outer side of the breast is disposed proximate the outer lateral edge surface of the foam. A mid-plane is disposed between the inner and outer lateral edge surfaces of the foam. An interface connects a leading edge surface of the foam and compressive surfaces. A portion of the leading edge surface which is aligned with the mid-plane is incompletely compressed.

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.

A tissue holder cap for covering a tissue holder includes a cover having a perimeter, the cover having an outer surface and an inner surface opposite from the outer surface. The cover includes a central portion having an opening configured for receiving a central post of the tissue holder, a first latch extending from the perimeter of the cover, and a second latch extending from the perimeter of the cover, circumferentially spaced apart from the first latch. The cover also includes a first protrusion configured to engage the post of the tissue holder. When the first protrusion engages with the post, each of the first latch and the second latch automatically aligns with one or more of a plurality of tabs on located on a circumferential sidewall of the tissue holder to thereby securely fasten the tissue holder cap onto the tissue holder.
