The laser surgical guidance system may generate a particular laser pattern from the line projection module, transmit the particular laser pattern outputted from the line projection module through a calibration tool including a collimator having a particular orientation, calculate an extrinsic parameter of the calibration tool in a projection image having passed through the calibration tool, and convert coordinates of the C-arm image into the line projection module coordinates using the extrinsic parameter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for calibration of laser targeting projector and C-arm image, recording medium for performing the same and laser surgical guidance system including calibration tool","description":"Provided is a laser surgical guidance system including a C-arm fluoroscopy (hereinafter, C-arm) to identify a patient's condition and support a surgical plan and a laser targeting projector to project","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11517394","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
