Radiographic medical imaging system using robot mounted source and sensor for dynamic image capture and tomography
First Claim
1. A radiographic imaging system, comprising:
- a penetrating radiation source including a first translating device, said first translating device comprising a first controller for positioning said radiation source;
a radiation image detector including a second translating device positioned on a side of a subject to be imaged opposite said radiation source, said second translating device comprising a second controller for positioning said detector, wherein radiation from said radiation source passes through said region of said subject to said detector; and
a motion capture device communicably connected to both said first and second controllers, said motion capture device tracking a position of said region of said subject and providing position information to both said first controller and second controllers for dynamically coordinating positions of said radiation source and said radiation detector for obtaining an image of said regionwherein said system provides unrestricted motion of said source relative to said detector;
wherein said system provides cone-beam computed tomography using imaging paths including paths other than a center of rotation located midway between said the source and said detector.

Abstract
A radiographic imaging system includes (100) a penetrating radiation source (110) including a first translating device (115), the first translating device (115) comprising a first controller (116) for positioning the radiation source. A radiation detector (120) includes second translating device (125) comprising a second controller for positioning the detector (120). A motion capture device (140) is communicably connected to both the first and second controllers. The motion capture device (140) tracks a position of the subject being imaged and provides position information to both the first controller (116) and second controllers (126) for dynamically coordinating trajectories for both the radiation source (110) and the radiation detector(120). The first and second translating devices preferably comprise robotic arms.
