12. The medical imaging device of claim 9 , wherein the locking device is automatically engageable during a movement of the x-ray source.
13. A medical imaging device, comprising:
an arm including a first end, a second end, an arc-shaped curvature between the first end of the arm and the second end of the arm, and a track extending along at least a portion of the arc-shaped curvature of the arm and terminating at the first end;
an x-ray detector fixed to the second end of the arm;
an x-ray source slidably coupled along a length of the track so that when the x-ray source is positioned at a maximum distance away from the x-ray detector and at the first end of the arm, the x-ray source and the x-ray detector are aligned along an imaging axis, and when aligned the x-ray source is configured to be at a predetermined constant source-to-image receptor distance (SID) from the x-ray detector, and
wherein the x-ray source being slidable to a position away from the first end of the arm and toward the x-ray detector; and
a controller associated with the x-ray source, the controller configured to automatically position the x-ray source along the length of the track.
14. The medical imaging device of claim 13 , wherein the x-ray source is coupled to the track by one of interlocking projections and a tongue and groove configuration.
15. The medical imaging device of claim 13 , wherein the controller is configured to automatically position the x-ray source to a pre-programmed position along the length of the track.
16. The medical imaging device of claim 13 , further comprising a user-interface, wherein the controller is operatively connected to the user-interface to enable a user to enter a desired position of the x-ray source along the length of the track, the user interface being selected from one of a computer, a keyboard, a mouse, a touchscreen, a tablet, a mobile phone, a foot pedal, and voice-assisted controls including a microphone and voice activation software controls configured to receive oral commands from the user to position the x-ray source along the length of the track.
17. The medical imaging device of claim 13 , further comprising a locking device to secure a position of the x-ray source along the length of the track.
18. A medical imaging device, comprising:
an arm including a first end, a second end, and an arc-shaped curvature between the first end of the arm and the second end of the arm, and
wherein the arm includes a track having a termination at the first end of the arm;
an x-ray detector fixed to the second end of the arm;
an x-ray source slidably coupled to the track,
wherein the track limits a sliding range of the x-ray source along the arc-shaped curvature from a first position proximate the x-ray detector to a second position located a maximum distance along the arc-shaped curvature away from the x-ray detector,
wherein the second position is defined by the termination of the track at the first end of the arm,
