FUNDING: Supported by projects TEC2013–48251-C2–1-R, DTS14/00192, PI15/02121 (Ministerio de Economía y Competitividad, ISCIII), TOPUS-CM S2013/MIT-3024 (Comunidad de Madrid) and FEDER funds.Background: A difficulty in computer-assisted interventions is acquiring the patient's anatomy intraoperatively. Standard modalities have several limitations: low image quality (ultrasound), radiation exposure (computed tomography) or high costs (magnetic resonance imaging). An alternative approach uses a tracked pointer; however, the pointer causes tissue deformation and requires sterilizing. Recent proposals, utilizing a tracked conoscopic holography device, have shown promising results without the previously mentioned drawbacks. Methods: We have developed an open-source software system that enables real-time surface scanning using a conoscopic holography device and a wide variety of tracking systems, integrated into pre-existing and well-supported software solutions. Results: The mean target registration error of point measurements was 1.46 mm. For a quick guidance scan, surface reconstruction improved the surface registration error compared with point-set registration. Conclusions: We have presented a system enabling real-time surface scanning using a tracked conoscopic holography device. Results show that it can be useful for acquiring the patient's anatomy during surgery.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/3D scanningconoscopic holographysurgical surfacesinfo:eu-repo/semantics/article10.1002/rcs.1788info:eu-repo/semantics/embargoedAccess
