Visualization of stereoscopic anatomic models of the paranasal sinuses and cervical vertebrae from the surgical and procedural perspective

Recent improvements in three‐dimensional (3D) virtual modeling software allows anatomists to generate high‐resolution, visually appealing, colored, anatomical 3D models from computed tomography (CT) images. In this study, high‐resolution CT images of a cadaver were used to develop clinically relevan...

Description
Summary:Recent improvements in three‐dimensional (3D) virtual modeling software allows anatomists to generate high‐resolution, visually appealing, colored, anatomical 3D models from computed tomography (CT) images. In this study, high‐resolution CT images of a cadaver were used to develop clinically relevant anatomic models including facial skull, nasal cavity, septum, turbinates, paranasal sinuses, optic nerve, pituitary gland, carotid artery, cervical vertebrae, atlanto‐axial joint, cervical spinal cord, cervical nerve root, and vertebral artery that can be used to teach clinical trainees (students, residents, and fellows) approaches for trans‐sphenoidal pituitary surgery and cervical spine injection procedure. Volume, surface rendering and a new rendering technique, semi‐auto‐combined, were applied in the study. These models enable visualization, manipulation, and interaction on a computer and can be presented in a stereoscopic 3D virtual environment, which makes users feel as if they are inside the model.
