Application Number: JP,2025-124625
Category (FI): A61B6/51,500,A61B6/12,A61B6/03,560@J,A61B6/40,530@C,A61B6/03,550@R
Stage: PROBLEM TO BE SOLVED: To correct a metal artifact.SOLUTION: The metal artifact correction includes projecting X-rays to scan a volumetric region of an object, the projecting generating corresponding cone beam computed tomography (CBCT) image data, reconstructing from the CBCT image data an extended CBCT volume representing the volumetric region and a volume outside the volumetric region, generating from the extended CBCT volume and a projection geometry a maximum intensity projection on a virtual plane, detecting attenuation image areas in the maximum intensity projection corresponding to metal, matching the detected attenuation image areas corresponding to metal to the CBCT image data, and reconstructing a final CBCT volume using the CBCT image data by suppression of areas of the CBCT image data corresponding to the detected attenuation image areas of the maximum intensity projection.SELECTED DRAWING: Figure 1 (Grant)
