METHODS AND APPARATUS FOR ESTIMATING THE POSITION AND ORIENTATION OF AN IMPLANT USING A MOBILE DEVICE |
摘要 |
Methods and apparatus for providing an overlay image of an implant during a surgical procedure using a mobile computing device are provided herein. The implant may include radio-opaque internal markers adjacent to and defining edges of the implant. The method may include: capturing an image of a imaging display device screen; estimating a pose of the implant based on the relationship between the 2-D positions of the radio-opaque internal markers and the 3-D positions of the radio-opaque internal markers; retrieving or generating a 3-D model image of the implant at the determined pose using the 3-D implant data; and overlaying the 3-D model image onto the image of the implant. The captured image may include the implant and at least two of the radio-opaque internal markers being visible as fiducial markers within the image. The fiducial markers may be 2-D positions of the radio-opaque internal markers in a 2-D plane. |
