A portable medical imaging system and method, of which the system includes a movable station having a movable C-arm, an imaging signal transmitter attached to the movable C-arm, and an imaging sensor positioned generally opposite to the imaging signal transmitter and attached to the movable c-arm. The imaging sensor is configured to rotate relative to a point approximately on a center axis of the movable C-arm independently of the imaging signal transmitter, so as to change an angle of incidence for a signal transmitted from the imaging signal transmitter to the imaging sensor, and provide a field-of-view that is larger than the field-of-view of the imaging sensor at a single position.
