Visualization of Superficial Cerebral Lesions Using a Smartphone Application.

ABSTRACT

AIM: Accurate localizations of cerebral lesions ensure good surgical outcomes and minimize intraoperative complications. Currently, microscope-integrated neuronavigation systems compensate these requirements. Since these units are expensive and large, the need to create more practical and portable systems in this "smart" century has become apparent. MATERIAL AND METHODS: The See-Through Camera smartphone application (app) is a photography app that penetrates the existing background picture and merges this with a camera image on the smartphone display. This app was applied to neurosurgery for visualization of the projection of the tumors over head in 20 patients. App accuracy was tested according to neuronavigation system. RESULTS: Precision of the app was evaluated according to the superposition ratio of the tumor image drawn by the navigation system with the tumor picture on the smartphone display. This ratio was 40%-100% in 16 (80%) patients and below 40% as an unfavorable result in the rest of the patients. CONCLUSION: Basic rationality of this app can provide the basis of future pocket navigation systems in terms of its design and principles.
