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

摘要

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 a line of the surgical plan directly onto an affected part through a line projection module which generates a laser. 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.
