Abstract
Improved systems and related methods for x-ray assisted breast biopsy and ultrasound-assisted breast biopsy are described. In one preferred embodiment, for example, an apparatus for facilitating both x-ray assisted and ultrasound assisted breast biopsy is provided, comprising a biopsy table for supporting a patient in a prone position between first and second opposing ends thereof, the biopsy table having first and second openings, respectively, toward each of the first and second ends, through which the patient'"'"'s breast may project depending on the patient'"'"'s orientation on the biopsy table. The apparatus further comprises an ultrasound-assisted biopsy system positioned beneath the first opening, and an x-ray-assisted biopsy system positioned beneath the second opening. In other preferred embodiments, the ultrasound-assisted biopsy system and x-ray assisted biopsy system are mechanically interchangeable beneath a single opening. In other preferred embodiments, novel integrations between specified components of the ultrasound-assisted and x-ray-assisted biopsy systems are provided.

4. An apparatus for facilitating image-guided breast biopsy procedures, comprising:
-
a biopsy table for supporting a patient in a prone position between first and second opposing ends of the biopsy table, the biopsy table having a first opening through which the prone patient'"'"'s breast may project when the patient is in a first orientation relative to said first and second ends of the biopsy table, the biopsy table having a second opening through the prone patient'"'"'s breast may project when the patient is in a second orientation relative to said first and second ends of the biopsy table; an ultrasound-assisted biopsy system positioned beneath said first opening, the ultrasound-assisted biopsy system comprising an ultrasound probe, a first biopsy instrument insertion platform, and first and second compressive members for compressing the breast along a first plane generally perpendicular to said biopsy table; an x-ray-assisted biopsy system positioned beneath said second opening, the x-ray-assisted biopsy system comprising an x-ray source, an x-ray detector, a second biopsy instrument insertion platform, and third and fourth compressive members for compressing the breast along a second plane generally perpendicular to said biopsy table; and a display system coupled to each of said ultrasound-assisted biopsy system and said x-ray-assisted biopsy system for displaying medical image information generated thereby. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. An apparatus for facilitating image-guided breast biopsy procedures, comprising:
-
a biopsy table for supporting a patient in a prone position, the biopsy table having an opening through which a breast of the prone patient projects; an ultrasound-assisted biopsy platform comprising an ultrasound probe, a first biopsy guide, a first biopsy instrument, and first and second compressive surfaces, the first and second compressive surfaces for compressing the breast along a first plane generally perpendicular to said biopsy table; an x-ray-assisted biopsy platform comprising an x-ray source, an x-ray detector, a second biopsy guide, a second biopsy instrument, and third and fourth compressive surfaces for compressing the breast along a second plane generally perpendicular to said biopsy table; and a display system coupled to receive medical images derived from said ultrasound probe and said x-ray detector and to display said medical image information; wherein said ultrasound-assisted biopsy platform and said x-ray-assisted biopsy platform are movably interchangeable relative to the opening such that ultrasound assisted biopsy and x-ray-assisted biopsy of the breast can be provided at different times. - View Dependent Claims (14, 15, 16, 17, 18)

19. An apparatus for facilitating image-guided breast biopsy procedures, comprising:
-
a biopsy table for supporting a patient in a prone position, the biopsy table having a first opening through which the prone patient'"'"'s breast projects; an ultrasound-assisted biopsy system comprising an ultrasound probe, a first biopsy guide, a first biopsy instrument, and first and second compressive members, the first and second compressive members for compressing the breast along a compression plane generally perpendicular to said biopsy table; an x-ray-assisted biopsy platform comprising an x-ray source, an x-ray detector, a second biopsy guide, a second biopsy instrument, and third and fourth compressive members for compressing the breast along said compression plane; a display system coupled to each of said ultrasound-assisted biopsy system and said x-ray-assisted biopsy system for displaying medical image information generated thereby; wherein said first and third compressive members are substantially adjacent, jointly movable along a direction substantially parallel to said compression plane, and coplanar along respective surfaces thereof that contact a first side of the breast; wherein said second and fourth compressive surfaces are substantially adjacent, jointly movable along the direction substantially parallel to said compression plane, and coplanar along respective surfaces thereof that contact a second side of the breast opposite the first side; wherein said apparatus is configured to be slidably switched between an ultrasound-assisted biopsy mode and an x-ray assisted biopsy mode, the breast remaining substantially motionless as said first and third compressive members are slidably interchanged beneath said first opening and as said second and fourth compressive members are slidably interchanged beneath said first opening. - View Dependent Claims (20, 21, 22, 23)
