Embodiment 1
[0041] Such as figure 1 As shown, it is an augmented reality-based navigation method for spinal minimally invasive surgery in Embodiment 1 of the present invention. The method includes the following steps:
[0042] S1. Reconstructing a virtual three-dimensional image of the patient's spine.
[0043] It specifically includes: reconstructing a virtual three-dimensional image of the patient's spine based on a set of CT images.
[0044] S2. Registering the virtual three-dimensional image with the patient space to obtain the position of the virtual lesion point in the virtual three-dimensional image in the patient space.
[0045] Wherein, registering the virtual 3D image with the patient space specifically includes: respectively setting 4 non-coplanar marker points in the virtual 3D image and the patient space, and aligning the 4 marker points in the virtual 3D image with the 4 marker points in the patient space. The two marker points coincide respectively, that is, the registrat...
Embodiment 2
[0052] A navigation system for spinal minimally invasive surgery based on augmented reality, which includes:
[0053] The image reconstruction module is used to reconstruct the virtual three-dimensional image of the patient's spine;
[0054] It specifically includes: reconstructing a virtual three-dimensional image of the patient's spine based on a set of CT images.
[0055] The first registration module is used to register the virtual three-dimensional image with the patient space to obtain the position of the virtual lesion point in the virtual three-dimensional image in the patient space;
[0056] Wherein, registering the virtual 3D image with the patient space specifically includes: respectively setting 4 non-coplanar marker points in the virtual 3D image and the patient space, and aligning the 4 marker points in the virtual 3D image with the 4 marker points in the patient space. The two marker points coincide respectively, that is, the registration is realized.
