Abstract
A system for quantitative computer graphic determination of positions on a patient's anatomy and positions on associated equipment located near the patient's anatomy in relation to anatomical data, as from CT or MR scanning. A first camera produces a quantitative electronic readout of its field-of-view which provides a determination of relative spacial coordinates of uniquely identifiable points in its field-of-view. A second camera produces a quantitative electronic readout of its field-of-view which provides a determination of relative spacial coordinates of uniquely identifiable points in its field-of-view. The two cameras are located with respect to the patient's anatomy and the associated equipment so that the fields-of-view of the cameras include both the patient's anatomy and the equipment, but are taken from different directions. A body marker is positioned with respect to the patient's anatomy at a known position relative to said patient anatomy. The body marker has known coordinates in a stereotactic coordinate system that is established relative to the patient's anatomy so that the coordinates of all identifiable points in the fields of view of the two cameras can be determined relative to the stereotactic coordinate system and related to imaging data.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
