摘要:
The invention relates to a method for locating a medical instrument during an intervention performed on the human body using an X-ray image recording system and an electromagnetic locating system whose systems of coordinates have been or will be mutually registered, with a first item of positional information about the instrument being obtained continuously by means of the locating system and in each case two two-dimensional X-ray images positioned at an angle to each other being intermittently recorded by means of the X-ray image recording system, from which images a second item of positional information about the instrument is determined and compared with the first item of positional information, after which the first item of positional information will be corrected depending on the comparison result taking account of the second item of positional information obtained from the X-ray images.
