摘要： The invention relates to a device for localizing tracking bodies (10), comprising at least one tracking body which is placed inside a physiological structure, and a means which is situated outside of the structure and which consists of sensor clusters (20) in a sensor cluster arrangement (55) as well as a method for localizing and influencing the tracking body. The tracking body is provided in the form of a body which is characterized by a finite remanent magnetization with a variable magnetic dipole moment and an anisotropic magnetic dipole field resulting therefrom. The sensor clusters (20) are provided in the form of a plurality of gradiometer sensors (30) with a specific measuring geometry. Optionally, physical/chemical properties and/or a trajectory of the tracking body may be altered in a specific manner by an externally acting magnetic field (H) and/or physiological processes in the environment of the at least one tracking body. In addition, it is possible to detect the location of a variable, in particular, a displaceable portion (57) which is associated with an expanded imaging means (60) of the sensor cluster arrangement (55) by means of a fixed portion (56) of the sensor cluster arrangement and to use the variable portion of the sensor cluster arrangement as a site marking in the expanded imaging arrangement.

摘要： An optical transmitting/receiving module including a support plate with passive reflectors, one or several optical fibers, a transmitter and a receiver. The support plate has a specular coating and therefore has an opaque surface. The surface of the support plate is structured by means of embossment or stamping. A surface emitting laser diode with a vertical resonator (VCSEL) may be particularly suitable as an optical transmitter in conjunction with a photodiode which serves as the receiver. The transmitting/receiving fibers may include multimode optical fibers.
