This video demonstrates using augmented reality (AR) for tumor resection, where a 3D-scanned tumor specimen is visualized as a hologram on a head-mounted display. Surgeons can manipulate and lock the hologram in place to ensure precise tumor removal.

Protocol

All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines.

NOTE: A schematic detailing the protocol workflow can be seen in Figure 1.

1. 3D Scanning

1. Obtain a 3D Scan of an oncologic resection specimen per the previously described 3D scanning protocol7.
   1. Set up the commercially available desktop 3D scanner in proximity to the pathology lab where specimens are typically taken.
   2. Gently rinse, and pat dry the resected specimen. Then, take 2D photographs of its anterior and posteri....
