Claim 10:
11. A computer-based method for image-guided implant placement, as a function of changes in patient position during a surgical procedure, the method comprising:
accessing, by at least one computing device configured by executing code stored in non-transitory processor readable media, an image captured at a first time and presenting a two-dimensional (“2-D”) antero-posterior (“AP”) view of a pelvis;
automatically identifying, by the at least one computing device, in the image captured at the first time and presenting the 2-D AP view of the pelvis, via a pixel-based artificial intelligence image recognition model, anatomical landmarks;
automatically measuring, by the at least one computing device, using the identified anatomical landmarks in the image captured at the first time and presenting the 2-D AP view of the pelvis, first distances and angles;
accessing, by the at least one computing device, an image captured at a second time and presenting a 2-D lateral view of the pelvis;
automatically identifying, by the at least one computing device, in the image captured at the second time and presenting the 2-D lateral view of the pelvis, via the pixel-based artificial intelligence image recognition model, the anatomical landmarks identified in the image captured at the first time and presenting the 2-D AP view of the pelvis;
automatically measuring, by the at least one computing device, using the identified anatomical landmarks in the image captured at the second time and presenting the 2-D lateral view of the pelvis, second distances and angles;
automatically determining, by the at least one computing device, at least as a function of the measured first distances and angles and the measured second distances and angles, absolute axial rotation of the pelvis in the image captured at the first time and presenting the 2-D AP view of the pelvis;
automatically determining, by the at least one computing device, as a function of the measured second distances and angles, sagittal tilt of the pelvis in the image captured at the second time and presenting the 2-D lateral view of the pelvis;
accessing during a surgical procedure, by the at least one computing device, an image captured at a third time and presenting a 2-D AP view of the pelvis;
automatically identifying during the surgical procedure, by the at least one computing device, in the image captured at the third time and presenting the 2-D AP view of the pelvis, via the pixel-based artificial intelligence image recognition model, the anatomical landmarks identified in the image captured at the first time and presenting the 2-D AP view of the pelvis;
automatically measuring during the surgical procedure, by the at least one computing device, using the identified anatomical landmarks in the image captured at the third time and presenting the 2-D AP view of the pelvis, third distances and angles;
automatically determining during the surgical procedure, by the at least one computing device, as a function of at least the measured second distances and angles and the measured third distances and angles, absolute axial rotation of the pelvis in the image captured at the third time and presenting the 2-D AP view of the pelvis;
automatically determining during the surgical procedure, by the at least one computing device, as a function of the measured first distances and angles, the measured second distances and angles, and the measured third distances and angles, a change in position of the pelvis in three-dimensional (“3-D”) space, including a change in sagittal tilt of the pelvis, from the image captured at the first time and presenting the 2-D AP view of the pelvis to the image captured at the third time and presenting the 2-D AP view of the pelvis;
automatically determining during the surgical procedure, by the at least one computing device, as a function of at least one of the determined absolute axial rotation of the pelvis in the image captured at the first time and presenting the 2-D AP view of the pelvis, the determined sagittal tilt of the pelvis in the image captured at the second time and presenting the 2-D lateral view of the pelvis, the determined absolute axial rotation of the pelvis in the image captured at the third time and presenting the 2-D AP view of the pelvis, and the determined change in sagittal tilt of the pelvis, an adjustment to a position of an implant; and
providing during the surgical procedure, by the at least one computing device, via a graphical user interface, information associated with the determined adjustment of the position of the implant.
