Embodiment Construction

[0048] figure 1 A perspective view of a magnetic resonance tomography system 7 with an object support 11 and a patient tunnel 8 is shown. A signal processing unit 5 is inter alia arranged within the housing of the magnetic resonance tomograph 7 . Signals pass from the magnetic resonance local coil 3 to the signal processing unit 5 . This is achieved by the contact system 1 according to the invention, which has the following elements:

[0049] Inductively based coil coupler elements 9 a , 9 b , 9 c , 9 d are arranged within an insertion guide element 10 arranged on the object support device 11 . Correspondingly, device coupler elements 13 a , 13 b , 13 c , 13 d are arranged in the region of guide groove 12 on bottom surface 6 of inductive-based magnetic resonance tomography device 7 . The coil coupler elements 9 a , 9 b , 9 c , 9 d are in electrical contact with the magnetic resonance local coil 3 via connection lines 27 via a row of plugs (not shown) integrated in the suppo...

Abstract

The present invention relates to a contacting system for contacting magnetic resonance local coils (3) with an unit for additional signal processing of a magnetic resonance blatt filming apparatus (7). The system is provided with a plurality of coil coupler elements (9, 9a, 9a', 9b, 9b', 9c, 9d) connected with the magnetic resonance local coils electrically, and apparatus coupler elements (13a; 13b; 13c) connected with the unit for additional signal processing electrically. The coil coupler elements and the apparatus coupler elements are fashioned so that, given a movement of the local coils along a movement path in the magnetic resonance data acquisition unit, a successive contacting of at least a portion of the coil coupler elements with apparatus coupler elements ensues at least over a specific path segment of the movement. In addition, the invention also relates to a method for contacting the magnetic resonance local coils (3) with an unit for additional signal processing, and a magnetic resonance blatt filming apparatus containing the contacting system.

Description

technical field [0001] The invention relates to a contact system and a method for contacting a magnetic resonance local coil with a signal processing unit of a magnetic resonance tomograph, and to a magnetic resonance tomograph with such a contact system. Background technique [0002] For examining human body parts, it is known to introduce the body part to be examined into a homogeneous magnetic field, the so-called fundamental field. The magnetic field causes an alignment of the nuclear spins of the nuclei in the body part, especially those of the hydrogen nuclei (protons) associated with water. These nuclei are excited into a precessional motion by means of high-frequency excitation pulses. After the excitation pulse has ended, the nuclei precess at a frequency that depends on the strength of the fundamental field and then return to the preferred direction of magnetization prescribed by the fundamental field after a predetermined relaxation time due to their spin. In th...
