Abstract
Proposed is a medical imaging system including: a C-arm including an X-ray source and a detector; a first plate installed on an X-ray path between the X-ray source and the detector, and including a first transmissive surface provided with a plurality of first ball markers blocking an X-ray, and a first optical marker; a second plate installed on the X-ray path between the X-ray source and the detector, and including a second transmissive surface provided with a plurality of second ball markers blocking the X-ray, and a second optical marker; a reference optical marker configured to provide a 3D reference coordinate system; an optical tracking device configured to recognize locations of the first and second optical markers and the reference optical marker; and a matcher configured to calculate a matching relationship between coordinates on a 3D reference coordinate system and locations on first and second captured images.
