New APCReg framework improves CBCT-IOS registration for surgical planning

By PulseAugur Editorial · [1 sources] ·

Researchers have developed APCReg, a novel framework for registering cone-beam computed tomography (CBCT) with intraoral scans (IOS). This method addresses challenges posed by disparate imaging modalities and potential pose offsets, which often lead to unreliable automated registration in clinical settings. APCReg employs a coarse-to-fine approach, utilizing multi-view anatomical coarse registration (MACR) for initial alignment and overlap-aware residual registration (OARR) for refinement, achieving a submillimeter mean Chamfer distance on test data.

    APCReg: Anatomical-Prior-Guided Coarse-to-Fine CBCT--IOS Registration via Multi-View Projection and Reliability-Controlled Residual Correction

    arXiv:2608.09993v1 Announce Type: cross Abstract: Registration between cone-beam computed tomography (CBCT) and intraoral scans (IOS) is essential for patient-specific surgical planning. However, disparate imaging modalities, limited overlap, and large pose offsets make automated…
