摘要

A method for positional optimisation of images in the case of the neural navigation in the surgery with an operation microscope and at least one optoelectronic image receiver as well as a computer system, in which the from the at least one image receiver obtained data information about the position of markings of a operation instrument and contain from the respective position data continuously or discontinuously the actual position of the instrument in the x - and y - as well as in the z - the direction of a three-dimensional coordinate system is determined, which - marking in the vicinity of the instrument tip are arranged and the maximum distance from the instrument tip is selected in such a way that the markings in the case of use in the field of view of the microscope are located; furthermore, the coordinate system the microscope system - is, for the position in the z - the direction of a distance determination by means of a depth of focus - evaluation or stereoscopic image evaluation takes place and the or the optoelectronic image receiver directly on the microscope - .sub.min - beam path are connected, characterized in that the position of the surgical microscope in the space detected and this surgical microscope - positional data are fed to the computer system, so that the instruments - positional data in..
