Abstract
A catheter locatable with a non-ionizing field, such as an electromagnetic or acoustic field, has a transmitting or receiving antenna for the relevant field at its tip. Receiving or transmitting antennas for the non-ionizing field are attached to a patient in which the catheter is disposed. A receiver or transmitter is connected to these antennas, and converts the received field waves into electrical locating or image signals. The location of the catheter tip is then portrayed on a display combined with an image of the blood vessel structure acquired in a different manner, such as by x-ray imaging.
