Embodiment Construction

[0031] One or more specific embodiments are described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be understood that, as in any engineering or design project, in the development of any such actual implementation, numerous implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with systems that may vary from implementation to implementation Relevant and business-related constraints. Furthermore, it should be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0032] When introducing elements of various embodiments of the present invention, the articles "a," "an," "the," and "said" are intended to mean that there are one...

Abstract

The invention relates to a visually guided biopsy system and method for mammography. A mammography system is disclosed that includes a biopsy guide system that employs a simplified robotic arm support to enable previously unusable locations to be combined with a visual guidance and control system for mounting a biopsy device directly to a mammography system, such as on a compression paddle. The vision system operates to determine the position of the biopsy device and the biopsy needle tip, and to control movement / operation of the biopsy guide system, such as to a terminal-most position or pre-firing position of the biopsy device to perform a biopsy procedure. The vision system utilizes one or more cameras to visually determine the position of the biopsy device relative to the biopsy region of interest within the desired tolerances of the biopsy procedure without the need to provide precise position information to the mammography system by the biopsy guidance system.

Description

technical field [0001] The present disclosure relates generally to mammography systems and devices, and more particularly to guidance systems for use with mammography devices. Background technique [0002] Embodiments of the present invention relate generally to X-ray medical imaging, and more particularly to systems and methods for performing a biopsy guided by stereotaxic mammography or digital breast tomosynthesis (DBT). Spectral mammography (SM) can also be used to guide the biopsy in 2D (CESM-guided biopsy) or 3D (CEDBT-guided biopsy), with or without contrast injection. [0003] Mammography (MG) is an X-ray imaging modality used to scan the breast for screening, diagnostic and / or interventional examinations. The effectiveness of X-ray mammography is affected by many factors, one of which is the two-dimensional (2D) rendering of the images obtained. [0004] Alternative systems to 2D X-ray mammography are also known for breast imaging. For example, a digital breast t...
