Markerless automatic 2D C scan and preoperative 3D image fusion procedure for medical instrument use uses image based registration matrix generation

摘要

A marker less automatic 2D C scan and preoperative 3D image fusion procedure uses image based registration (S3) of a preoperative image E (S1) and an interoperative image D (S2) to give a registration matrix MED, registers a C frame tool plate using a navigation system (S4) and takes a C frame 2D fluorescence image C (S5) to create a projection matrix LDC (S6) for fusion (S7) of D with E using the matrix MED. Includes an INDEPENDENT CLAIM for a C scan unit using the procedure.
