MedPCFM: Improving Medical Point Cloud Completion by Integrating Point Transformers and Flow Matching
arXiv:2606.24433v1 Announce Type: cross Abstract: Medical point cloud completion is important for anatomical reconstruction and downstream clinical workflows, yet generative modeling in this setting remains insufficiently studied. We investigate completion through continuous-time generative modeling and introduce PCFM, a PTv3-backed flow matching approach for medical point cloud completion. We evaluate on SkullFix and SkullBreak, and additionally on the more recent Mandibular Defect dataset. We build strong baselines by adapting PTv3 to a deterministic encoder-decoder completion model and by i
The rapid advancement of generative AI models, especially in transformer architectures and flow matching, is enabling new applications in complex data domains like medical imaging.
Improving medical point cloud completion is critical for developing more accurate anatomical reconstructions, which can significantly enhance diagnostic capabilities and guide clinical procedures.
The introduction of PCFM demonstrates a more robust approach to 3D medical data reconstruction for generative modeling, potentially leading to higher fidelity virtual anatomy.
