1. An imaging system comprising:
an immobilization structure configured to immobilize a breast of a patient;
an x-ray source movable along a path relative to the breast of the patient and configured to emit a plurality of x-ray exposures during movement of the x-ray source;
an x-ray detector; and
an anti-scatter grid disposed between the x-ray source and the x-ray detector, the anti-scatter grid including a plurality of septa oriented substantially parallel to a coronal plane of the patient,
wherein the x-ray detector and the anti-scatter grid are rotatable around a fixed axis within the imaging system so as to maintain orientation with the x-ray source, and
wherein the anti-scatter grid is movable relative to at least one of the x-ray source and the x-ray detector during emission of the plurality of x-ray exposures from the x-ray source.
 
9. A multi-modal imaging system comprising:
an immobilization structure configured to immobilize a breast of a patient, the immobilization structure including a support platform;
an x-ray source operable in at least a first imaging mode and a second imaging mode;
an x-ray detector disposed on a side of the support platform that is opposite of the x-ray source; and
a retractable anti-scatter grid disposed between the x-ray detector and the support platform,
wherein in the first imaging mode, the x-ray source is configured to emit a plurality of first x-ray exposures during movement of the x-ray source while the anti-scatter grid is disposed between the x-ray detector and the support platform, and
wherein in the second imaging mode, the x-ray source is configured to emit at least one second x-ray exposure while the anti-scatter grid is retracted from between the x-ray detector and the support platform.
