A device for determining the position of a medical instrument that is introduced into an object to be examined is also used for imaging the vicinity of the medical instrument. In order to enable the acquisition of instantaneous position information and image information from the vicinity of the medical instrument for all kinds of medical instruments, a localization device that is arranged in the end zone of the medical instrument that is to be introduced determines the position of the medical instrument within the object to be examined; at the same time image information is acquired in the vicinity of the medical instrument by an image acquisition device that is arranged on the medical instrument and on the basis of the position thus determined the position of the medical instrument ( ) is reproduced in a survey image of the object to be examined and images of the vicinity of the object to be examined are displayed on the basis of the image information acquired.

Method and apparatus for intravascular localization and imaging without X-rays

The invention relates to a fiber-optical sensor, comprising a light transmitter device (6) which couples transmitted light into at least one first ligthwave conductor (3,4) and also comprising a light receiver device (7) which receives light from the first lightwave conductor and at least one second lightwave conductor (4,3). The lightwave conductors (3,4) comprise adjacently situated portions (1) which can contact one another in a light-transferring manner at given areas and which are accommodated together in an envelope (5) at this area, a force or a pressure being applied to the lightwave conductor via said envelope. The light transmitter device (6) also couples a first transmitted light into the first lightwave conductor (3,4) and a second transmitted light into the second lightwave conductor (4,3).
