OG exemplary drawing
 
1. An apparatus comprising:
a base;
an equipment support platform linearly positionable relative to the base;
a tomosynthesis imaging system rotatably secured to the equipment support platform for imaging a breast of a patient, wherein the tomosynthesis imaging system is rotatable about an imaging system rotation axis, wherein the tomosynthesis imaging system comprises an x-ray source and a receptor;
a stage arm assembly rotatably secured to the equipment support platform, wherein the stage arm assembly comprises a biopsy needle configured to obtain a tissue sample from the breast of the patient, wherein the stage arm assembly is rotatable about a stage arm assembly rotation axis; and
a breast support assembly linearly positionable along the equipment support platform, wherein the breast support assembly is configured to immobilize the breast of the patient during an image-guided biopsy procedure, wherein the breast support assembly comprises a breast support platform and a compression paddle, the breast support platform integral with a protective cover enclosing the receptor.
 
20. A method of performing an image-guided biopsy procedure, the method comprising:
extending a breast of a patient through an opening of a patient support table when the patient is in a prone position;
compressing the breast of the patient with a breast support assembly, wherein the breast support assembly is linearly positionable relative to an equipment support platform disposed below the table, wherein the breast support assembly includes a breast support platform and a compression paddle that the breast of the patient is compressed between;
rotatably positioning a tomosynthesis imaging system about an imaging system rotation axis, wherein the tomosynthesis imaging system is rotatably secured to the equipment support platform for imaging the breast of the patient, wherein the tomosynthesis imaging system is positionable independent of the breast support assembly, wherein the tomosynthesis imaging system includes an x-ray source and a receptor, the receptor enclosed within the breast support platform that is integral with a protective cover; and
rotatably positioning a stage arm assembly relative to the breast support assembly, wherein the stage arm assembly is positionable independent of the breast support assembly, and wherein the stage arm assembly comprises a biopsy needle configured to obtain a tissue sample from the breast of the patient, wherein the stage arm assembly is rotatable about a stage arm assembly rotation axis and positionable along a Z-axis, the Z-axis being oriented in a same direction as at least one of the imaging system rotation axis and the stage arm assembly rotation axis.
