Abstract

The invention relates to a catheter for brachytherapy having a radiation source for generating beta or gamma rays. So that the catheter can be positioned as precisely as possible it is inventively proposed to provide an NMR device in the area of a free end of the catheter for generating and detecting NMR signals created through magnetic resonance of the atomic nucleus.

Description

technical field

[0001] The present invention relates to a catheter. The invention also relates to a catheter device, and an imaging diagnostic device comprising the catheter or the catheter device. Background technique

[0002] One such catheter is disclosed in WO 97 / 25102A1. In practice, the problem arises when using known catheters that the radiation source is often not positioned with the required accuracy in the blood vessel to be treated.

[0003] In order to eliminate this disadvantage, known catheters are combined with imaging devices. In this case, for example, there are devices which generate images on the basis of ultrasound signals. Such a device is known for example from EP0885594.

[0004] US 6,377,048 B1 and US 6,704,594 B1 describe a catheter with an NMR device for generating and acquiring NMR signals induced by magnetic resonance of atomic nuclei. The NMR device makes it possible to create two-dimensional or three-dimensional images of the tissue surroun...
