Embodiment 1
[0149] Two sets of CT and MRI images of "fourth lumbar vertebrae / fifth lumbar vertebral right lateral recess stenosis combined with fifth lumbar upper endplate vertebral posterior edge disconnection" were used to construct a 3D model, and then registered and fused into a 3D model Designing the surgical approach for percutaneous transforaminal discectomy.
[0150] In this embodiment, in the three-dimensional model of the lumbar spine that is registered and constructed by the method of the present invention, the three-dimensional model of the lumbar intervertebral disc, dural sac and nerve root is consistent with the three-dimensional model of the lumbar intervertebral disc, dural sac and nerve root established using computer tomography data. It has the advantages of accurate spatial position, clear and smooth outline, and clear adjacency relationship.
[0151] see Figure 1-1 to Figure 1-21 As shown, the present embodiment a kind of method for registration fusion CT and MRI si...
Embodiment 2
[0273] Two sets of CT and MRI two-dimensional images of "third lumbar vertebra / fourth lumbar disc herniation combined with third lumbar lower endplate vertebral body disconnection" were used to construct a three-dimensional model, and then registered and fused into a three-dimensional model. Design the surgical approach, 3D print the physical model, and compare and analyze the preoperative and postoperative results of transforaminal endoscopic discectomy.
[0274] In this embodiment, the three-dimensional model of the lumbar intervertebral disc registered and constructed by this method has a higher spatial resolution than the lumbar intervertebral disc model established based on the routine examination sequence (T1WI sequence, T2WI sequence, T2FS sequence) data of magnetic resonance imaging. It has the advantages of accurate spatial position, clear and smooth outline, and clear adjacency relationship.
[0275] see Figure 2-1 to Figure 2-25 As shown, a method of registering a...
