Abstract
An imaging system can be configured to merge a three-dimensional (“3D”) mesh based on a magnetic resonance imaging (“MRI”) image of an anatomical feature to a fluoroscopy image of the anatomical feature. The imaging system can include a computer platform configured to perform operations. The operations can include obtaining the 3D mesh based on the MRI image. The operations can further include obtaining the fluoroscopy image. The operations can further include determining a registration seed. The operations can further include registering the 3D mesh based on the MRI image to the fluoroscopy image using the registration seed.

An imaging system configured to merge a three-dimensional (“3D”) mesh based on a magnetic resonance imaging (“MRI”) image of an anatomical feature to a fluoroscopy image of the anatomical feature, the imaging system comprising a computer platform configured to perform operations comprising:
- obtaining the 3D mesh based on the MRI image;
- obtaining the fluoroscopy image;
- determining a registration seed;
- and
- registering the 3D mesh based on the MRI image to the fluoroscopy image using the registration seed,
- wherein determining the registration seed comprises:
- determining an estimated 3D model based on the fluoroscopy image;
- and
- determining the registration seed by registering the 3D mesh based on the MRI with the estimated 3D model based on the fluoroscopy image.
A method of operating an imaging system to merge a three-dimensional (“3D”) mesh based on a magnetic resonance imaging (“MRI”) image of an anatomical feature to a fluoroscopy image of the anatomical feature, the method comprising:
- obtaining the 3D mesh based on the MRI image;
- obtaining the fluoroscopy image;
- determining a registration seed;
- and
- registering the 3D mesh based on the MRI image to the fluoroscopy image using the registration seed,
- wherein registering the 3D mesh based on the MRI image to the fluoroscopy image comprises:
- determining a digitally reconstructed radiograph based on the 3D mesh based on the MRI image;
- and
- registering the digitally reconstructed radiograph to the fluoroscopy image.
A computer program product comprising:
- a non-transitory computer readable medium storing instructions executable by a computer platform of an imaging system to merge a three-dimensional (“3D”) mesh based on a magnetic resonance imaging (“MRI”) image of an anatomical feature to a fluoroscopy image of the anatomical feature, the computer platform when executing the instructions causes the imaging system to perform operations comprising:
- obtaining the 3D mesh based on the MRI image;
- obtaining the fluoroscopy image;
- determining a registration seed;
- and
- registering the 3D mesh based on the MRI image to the fluoroscopy image using the registration seed,
- wherein obtaining the 3D mesh based on the MRI image comprises:
- receiving an MRI image of the anatomical feature;
- obtaining a nearest neighbor computerized topography (“CT”) template relative to the MRI image;
- and
- generating the 3D mesh of the anatomical feature based on the MRI image and the nearest neighbor CT template.
