ÜBERSETZUNG DER PATENTANSPRÜCHE DER EUROPÄISCHEN PATENTANMELDUNG 85 304 000.4 (0 165 742)
1. Kombination aus einem Magnetresonanz-Abbildungssystem zum Darstellen der räumlichen Verteilung eines einen ausgewählten magnetischen Parameter charakterisierenden Gewebebestandteils eines Subjektes und einem Katheter zum Einsetzen in dieses Subjekt, wobei der Katheter ausgebildet ist, um steuerbar das Magnetfeld im Bereich eines lokalen Teils des Katheters zu stören.
2. Kathetervorrichtung, gekennzeichnet durch eine hohle Hülse, die einen flexiblen, länglichen Isolator enthält;
ein Paar leitfähiger Streifen, die in dem Isolator eingebettet sind und sich im wesentlichen über dessen Länge erstrecken;
eine in die Hülse eingebettete, leitfähige Schleifenanordnung, die in der Nähe eines Endes der Hülse angeordnet ist und die leitfähigen Streifen gegenseitig miteinander verbindet;

eine Erregereinrichtung zum Zuführen eines Stromes durch die leitfähigen Streifen und somit durch die Schleife, wodurch ein steuerbares Dipolmagnetfeld in deren Nähe erzeugt wird.
3. Verfahren zum Ermitteln der räumlichen Beziehung eines Katheters in einem Körper gegenüber Organen des Körpers, gekennzeichnet durch
Einsetzen des Katheters in den Körper, Erzeugen eines schwachen Magnetfeldes am Ende des Katheters, wodurch die magnetische Abbildung lokal gestört wird, und
Erzeugung einer Magnetresonanz-Abbildung des Körpers.
