Abstract
A station for tomotactic-guided biopsy in prone includes a table with an aperture, and a tomosynthesis imaging system. A biopsy gun can be mounted on a stage arm assembly disposed below the table. The imaging system and stage arm assembly can be independently rotated and linearly repositioned in one or more dimensions, thereby allowing the tomotactic scan axis to be located relative to a breast being imaged.
Claims19
An apparatus comprising:
- a table comprising a base for supporting a patient in a prone position, wherein the table extends substantially along an X-dimension and a Y-dimension, and the base extends substantially along a Z-dimension, each dimension being substantially orthogonal to one another;
- an equipment support platform coupled to the base by one or more slide assemblies, wherein the equipment support platform extends from the base and is disposed below the table, and wherein the equipment support platform is configured to slide relative to the base along the X-dimension, the Y-dimension, and the Z-dimension;
- a tomosynthesis imaging system for imaging a breast of the patient, the tomosynthesis imaging system comprising an imaging support platform pivotally connected to the equipment support platform and supporting an x-ray source and a receptor, wherein the tomosynthesis imaging system is rotatable about a rotation axis parallel to the Z-dimension and defined between the x-ray source and the receptor;
- a stage arm assembly for obtaining a tissue sample from the breast of the patient imaged by the tomosynthesis imaging system, the stage arm assembly comprising a stage arm support platform connected to the equipment support platform and configured to support a biopsy needle;
- and
- a breast support assembly for compressing the breast of the patient, the breast support assembly comprising a breast support platform connected to the equipment support platform and supporting a compression paddle and a breast platform.

A method comprising:
- positioning a patient on a table in a prone position, the table including a base having an equipment support platform extending therefrom and disposed below the table, wherein the table extends substantially along an X-dimension and a Y-dimension, and the base extends substantially along a Z-dimension, each dimension being substantially orthogonal to one another;
- aligning the equipment support platform with a breast of the patient, wherein the equipment support platform is coupled to the base by one or more slide assemblies and is configured to slide relative to the base in the X-dimension, the Y-dimension, and the Z-dimension;
- compressing the breast of the patient between a compression paddle and a breast platform of a breast support assembly, wherein the breast support assembly includes a breast support platform connected to the equipment support platform and supporting the compression paddle and the breast platform;
- imaging the breast of the patient with a tomosynthesis imaging system, wherein the tomosynthesis imaging system includes an imaging support platform pivotally connected to the equipment support platform and supporting an x-ray source and a receptor, and wherein the tomosynthesis imaging system is rotatable about a rotation axis defined between the x-ray source and the receptor;
- positioning a biopsy needle by configuring a stage arm assembly using information from the tomosynthesis imaging system, wherein the stage arm assembly includes a stage arm support platform configured to support the biopsy needle;
- and
- obtaining a tissue sample from the breast of the patient imaged by the tomosynthesis imaging system.
