Automatic fluoroscopic Image Calibration for Traumatology Intervention Guidance

摘要

Fluoroscopic images are often used in surgery but they are difficult to exploit in computer aided medical intervention because of their numerous disadvantages. A simple method, compatible with surgical use, is presented and applied to a common operation in traumatology: the distal targeting during intra-medullary nailing. We will also show how calibrated data from fluoroscopy imaging system combined to virtual reality techniques can guide the surgeon in such difficult tasks.
