Image-guided surgery: preliminary feasibility studies of frameless stereotactic liver surgery.
BACKGROUND Liver surgery can be difficult because there are few external landmarks defining hepatic anatomy and because the liver has significant vascularity. Although preoperative tomographic imaging (computed tomography or magnetic resonance imaging) provides essential anatomical information for operative planning, at present it cannot be used actively for precise localization during surgery....
متن کاملHealth technology assessment of image-guided radiotherapy (IGRT): A systematic review of current evidence
Background: Image-guided radiotherapy used multiple imaging during the radiation therapy course to improve the precision and accuracy of health care provider's treatment. Objectives: This study aims to assess the safety, effectiveness and economic aspects of image-guided radiation therapy for decision-making about this technology in Iran. Methods: In this study, the most important med...
متن کاملInteractive navigation-guided ophthalmic plastic surgery: the utility of 3D CT-DCG-guided dacryolocalization in secondary acquired lacrimal duct obstructions
AIM The aim of this study was to report the preliminary experience with the techniques and utility of navigation-guided, 3D, computed tomography-dacryocystography (CT-DCG) in the management of secondary acquired lacrimal drainage obstructions. METHODS Stereotactic surgeries using CT-DCG as the intraoperative image-guiding tool were performed in 3 patients. One patient had nasolacrimal duct ob...
متن کاملSafety margins in robotic bone milling: from registration uncertainty to statistically safe surgeries.
BACKGROUND When robots mill bone near critical structures, safety margins are used to reduce the risk of accidental damage due to inaccurate registration. These margins are typically set heuristically with uniform thickness, which does not reflect the anisotropy and spatial variance of registration error. METHODS A method is described to generate spatially varying safety margins around vital ...
متن کاملImage-guided surgery and craniofacial applications: mastering the unseen.
Image-guided surgery potentially enhances intraoperative safety and outcomes in a variety of craniomaxillofacial procedures. We explore the efficiency of one intraoperative navigation system in a single complex craniofacial case, review the initial and recurring costs, and estimate the added cost (e.g., additional setup time, registration). We discuss the potential challenges and benefits of ut...
