Classification: CPC A | IPC A

Claim 7:
8. A portable medical imaging system comprising:
a movable station comprising a double telescoping C-gantry, the C-gantry including movable first and second C-arms;
an imaging signal transmitter attached to the movable first C-arm; and
an imaging sensor positioned opposite to the imaging signal transmitter and attached to the movable first C-arm, wherein the imaging sensor defines an angle of incidence with respect to a signal emitted from the imaging signal transmitter,
wherein, at an initial position the imaging sensor and the imaging signal transmitter define a central axis, the central axis being between the imaging sensor and the imaging signal transmitter and being the central axis of the gantry, and an isocenter located at the central axis and being equidistant between the imaging signal transmitter and the imaging sensor,
wherein the angle of incidence is defined as a first line from a focal point of the imaging signal transmitter to a middle of the imaging sensor and a second line normal from the imaging sensor to the isocenter,
wherein the angle of incidence is zero at the initial position, wherein the imaging sensor is configured to rotate about the isocenter and relative to a point approximately on a central axis of the movable first 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 while the second line remains normal from the imaging sensor to the isocenter, and provide a field-of-view that is larger than the field-of-view of the imaging sensor at a single position,
wherein the C-gantry is moved to minimize a zone of collision, the zone of collision being an annular area defined by an extent of possible positions for the imaging sensor.
