1. A breast immobilization device for magnetic resonance imaging (MRI) assisted biopsy of a breast having a medial or lateral side of the breast extending along a biopsy grid extending along a plane and an opposite side of the breast extending along a flat plate extending parallel to the plane, the device comprising:
an expandable volume positioned between the biopsy grid and the flat plate, in a first unexpanded position, having a first thickness measured perpendicular to the plane, and in a second expanded position, having a second thickness measured perpendicular to the plane that is greater than the first thickness;
wherein the volume in the second expanded position exerts a force against the opposite side of the breast to press the medial or lateral side of the breast against the biopsy grid.
 
16. A method of breast immobilization for magnetic resonance imaging (MRI) assisted biopsy of a patient breast, the method comprising:
extending a medial or lateral side of the patient breast along a biopsy grid extending along a plane and an opposite side of the breast along a flat plate extending parallel to the plane;
positioning an expandable volume between the biopsy grid and the flat plate, wherein in a first unexpanded position, the volume has a first thickness measured perpendicular to the plane, and in a second expanded position, the volume has a second thickness measured perpendicular to the plane that is greater than the first thickness;
exerting a force against the opposite side of the breast to press the medial or lateral side of the breast against the biopsy grid in the second expanded position of the volume.
