Claim 0:
1. A computer-based system for image-guided implant placement, as a function of changes in patient position during a surgical procedure, the system comprising:
at least one computing device configured by executing code stored in non-transitory processor readable media to:
access an image captured at a first time and presenting a two-dimensional (“2-D”) antero-posterior (“AP”) view of a pelvis;
automatically identify 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 measure, 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;
access an image captured at a second time and presenting a 2-D lateral view of the pelvis;
automatically identify 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 measure, 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 determine, as a function of at least 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 determine, 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;
access during a surgical procedure, an image captured at a third time and presenting a 2-D AP view of the pelvis;
automatically identify during the surgical procedure, 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 measure during the surgical procedure, 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 determine during the surgical procedure, at least as a function of 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 determine during the surgical procedure, 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 determine during the surgical procedure, 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 second 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
provide automatically determine during the surgical procedure, via a graphical user interface, information associated with the determined adjustment of the position of the implant.
