The main questions it aims to answer are:\n\n• AR based neuronavigation system can achieve accuracy that is not inferior to conventional intraoperative navigation system.\n\nParticipants will participate the study after informed consent. When participants undergo surgery for their brain tumor, we will set up 2 types of neuronavigation, conventional navigation system and developed AR based neuronavigation system. Surgeon will plan and conduct surgery based on only conventional navigation system, but 3D errors at several selected points between two types of navigation will be measured and analyzed.', 'detailedDescription': 'Being developed AR navigation were reported in our following papers:\n\n1.

(doi.org/10.3171/2021.5.FOCUS21184)\n\nThis study aims to evaluate the accuracy of anatomical localization of a newly developed augmented reality-based neurosurgery navigation. After 3-dimensional (3D) modeling of the brain of a patient with brain tumor or cerebral vascular disease through 3D image segmentation extraction and modeling, the Augmented Reality (AR)-based navigation developed by this research team can be used with a commercially available visualization device, such as iPad, iPhone, and Hololens2, to evaluate the accuracy.\n\nThe AR-based navigation obtained approval from the Ministry of Food and Drug Safety of Republic of Korea (class 2 medical device) in February 2022. Through this clinical tria that compare accuracy with existing conventional intraoperative neuronavigation system, we will evaluate whether it shows equivalent performance to replace the existing navigation.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Adult patients aged 18 years or older who underwent MRI or CT scan due to brain tumor or cerebrovascular disease\n* Adult patients aged 18 years or older who need surgical treatment using navigation for brain tumor or cerebrovascular disease\n\nExclusion Criteria:\n\n* Cases where application of navigation is not necessary according to the judgment of the researcher or surgeon\n* When the patient or guardian does not agree\n* Patients with anatomical deformation due to previous surgery or requiring emergency surgery'}, 'identificationModule': {'nctId': 'NCT05776706', 'briefTitle': 'Clinical Trial for the Validation of AR Based Neuronavigation System', 'organization': {'class': 'OTHER', 'fullName': 'Seoul National University Hospital'}, 'officialTitle': 'Clinical Trial for the Evaluation of the Accuracy of Augmented Reality Based Neuronavigation System', 'orgStudyIdInfo': {'id': 'SNUH-AR001'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Single arm', 'description': "We will set up 2 navigation systems, newly developed AR-based navigation and conventional navigation system, to surgeries of all participants.\n\nSurgeons will perform all surgical planning and operations with reference to the conventional navigation system.
