A SYSTEM FOR MEASURING THE TRUE DIMENSIONS AND ORIENTATION OF OBJECTS IN A TWO DIMENSIONAL IMAGE

摘要

The surgical navigation system comprises:
a surgical tool designed to perform a surgical process and including a set of markers visible in medical images and having known spatial relationships between them;
a receiving circuitry adapted to receive a given medical image, which given medical image includes the surgical tool and an organ of a subject;
and an image processing circuitry adapted to identify said markers in the given medical image, to determine a location and orientation of the surgical tool based on the location of the identified markers in the image; and to generate and render an overlay on the image derived from the determined location and orientation.
