Image Guided Surgery (IGS) – Definition?
• General term used for any surgical procedure where surgeons employs tracked surgical instruments in conjunction with preoperative or intraoperative images in order to indirectly guide the procedure
• IGS was originally developed for treatment of brain tumors
• Various applications of navigations for neurosurgery have been widely used for almost two decades

Intraoperative pulmonary nodule tracking with CBCT and deformable image registration
• Pilot clinical study to acquire cone-beam CT images during VATS
• Lung deflation for VATS decreased CT image contrast, so nodules cannot be distinguished directly
• Image registration methods help determine the correspondence of regions between CT images
• Registering the cone-beam CT images of the inflated lung to the deflated lung helps “project” the known nodule location to the deflated lung
