Patent ID: 7806589

Claim:
An apparatus for dynamic radiographical imaging of skeletal motion of a subject, comprising: a first overhead support structure comprising a first vertically and horizontally adjustable source arm having a first source arm upper guide configured with a first hollow portion, the source arm positions a first radiological imaging source at a first source position and comprising a first vertically and horizontally adjustable imaging arm having a first imaging arm upper guide configured with a second hollow portion, the imaging arm positions a first radiological imaging receiver at a first imaging position selected for radiological imaging on a first axis passing through a selected portion of the subject; a second overhead support structure comprising a second vertically and horizontally adjustable source arm that positions a second radiological imaging source at a second source position and comprising a second vertically and horizontally adjustable imaging arm that positions a second radiological imaging receiver at a second imaging position selected for radiological imaging along a second axis intersecting the first axis and passing through the selected portion of the subject, wherein opposing ends of the second overhead support structure slideably enter the first hollow portion or the second hollow portion to facilitate orientation of the first axis and the second axis; position references coupled between the first and second support structures that determine relative orientation between the first and second axes; and an imaging system that generates three-dimensional radiology image data that dynamically changes as the subject moves by processing bi-planar radiological imaging data received from the first and second imaging receivers.
