Title:
MULTIPLE SURFACES FOR PHYSICAL-TO-IMAGE/IMAGE-TO-PHYSICAL REGISTRATION AND IMAGE VERIFICATION
Document Type and Number:
WIPO Patent Application WO/2018/152742
Kind Code:
A1
Abstract:
This invention is about a novel image registration. This rigid registration is based on multiple surfaces arranged in a 3D relationship in the Cartesian coordinate system through a fiducial marker. In comparison to surface-based registration, this registration process provides more accurate registration or requires a smaller fiducial marker for the same level of registration accuracy. Moreover, this fiducial marker enables measuring coordinates in the physical domain; therefore the registration error can be measured by comparing coordinates of specific points in both physical and virtual domains. This has a potential application in comparing the imaging physical-to-image (PI) or printing image-to-physical (IP) modalities, for example, to compare the accuracies of the 3D model created by computed tomography and optical scanners. Other potential application also includes assisting a surgical navigation in a dental implant placement. The proposed fiducial marker therefore has potential development in the application of virtual reality.
